Lithium Jump Starters

[SeanC]

A while back I bought a Micro-Start XP-10 Jump Starter.

I have used it on my Mazda 3 and it worked.

Today I was working on the D3 with the stereo on, but didn’t realise that the air-con fan was running. So dead battery. Wouldn’t turn over. I could have used the auxiliary battery but decided to try the jump starter.

Was sceptical but it worked. Didn’t kick over like a starting battery of course but did the job.

[trout1105]

When I first tried one of these out I was VERY Sceptical But I had No dramas at all starting a Hilux 4 cyl diesel. For their size these things pack quite a punch [thumbsupbig]

[donh54]

I bought a cheap one as a power pack for the phone etc. Was very pleasantly surprised when it jump started a Barina that could barely wind itself over!

Ain't modern electromagical stuff bloody marvelous! [thumbsupbig]

[Mike57]

My mate with a 2.7L D4 had a completely flat battery and the RACV guy needed to use two of these packs to get it started.

[rsp]

We are off to the snow for a week but the combined draw of the Traxide dual battery system and a Haltek performance chip is around 250ma until the Traxide timer reduces the draw from the smart switch.

I am not sure how long the battery will hold enough charge to crank especially as it will be parked in the open and I will not be able to charge it. Hence I was thinking of buying a battery Jump Starter pack as Insurance or use the Ctek MXS 15 in Supply mode if the battery does not crank the motor, as I should be able to plug in the Ctek to start the car. The alternative is a jump start pack, but it looks like I would need a pretty big one given the cold cranking amps required.

I usually charge the battery around every 3 or so days in the colder months as we do mostly short trips. We live in (cold) Goulburn!

A jump start pack could be useful outback but lugging one around all the time, plus the cost (over $300 from Super Cheap) are an issue.

[Eric SDV6SE]

About 2 years ago one of those lithium jump start packs could not crank over the 3.0L D4 despite being fully charged. I now carry a Black and Decker 350cca (Nominal) jump starter in the camper when we are out bush.

I believe these lithium jump starters are better now

[shanegtr]

My old man got on a while ago. Had to use it last year to start my Suburban which had a flat battery - it fired up the big block 454 perfectly.

[BradC]

Most of them (like all the ones I've looked at) work by putting a very fast surface charge on the battery. Works great for a good battery gone flat, but not so much for a genuinely dead starting battery (like dropped one or more cells/high internal resistance).

I do the same thing with a ryobi one+ 18V battery. Put it in series with a 55w headlamp bulb and onto the dead battery. The headlamp bulb provides enough resistance to stop the ryboi tripping out on overcurrent and quickly puts a surface charge on the car battery. I always have at least one ryobi battery in the car.

[Eevo]

ive found these jump starters dont last more than a year or 2

[SeanC]

I’ve used mine a number of times now. If you get in the vehicle and there is enough charge to just turn the engine over then it works fine. Try starting once if it fails connect the jump starter. I haven’t used it on a really flat battery but I don’t think it would work.

..... I do the same thing with a ryobi one+ 18V battery. Put it in series with a 55w headlamp bulb and onto the dead battery. The headlamp bulb provides enough resistance to stop the ryboi tripping out on overcurrent and quickly puts a surface charge on the car battery....
That’s a good option. So is that connected like the rough sketch attached?

Spot on. The light bulb is a non-ohmic resistance with a very high temperature coefficient, so it'll pass way more than 4A at low differential voltages while the filament is cold. If the car draws too much current the filament starts to heat up and its resistance rises limiting the current.
I've never bothered to try and characterize it. It's just the first time I needed to do it I happened to have a spare H4 in the tool box and it did the job.

One of my "get out of jail free" cards. A bit like the time I boosted my Volvo using 3 Duracell 6V lantern batteries in series. They have a relatively high internal resistance, so that was no worries. Just enough to put a surface charge on to get it going. Took about 20 minutes to put a sufficient charge in. The Ryobi does it in about 10. One of those things, the longer you wait the better the outcome is likely to be, and if you're in the middle of nowhere it's a good outcome you want!

Of course the second time I did it the results were not as good. Might have had something to do with me forgetting to turn the park lights off though.

My thanks to everyone who has responded to my query.

Brad I am almost a complete ignoramus when it comes to batteries so are you able to provide a bit more information as to exactly how you connect up the Ryobi battery to the cranking battery please? I assume that a 2.5Ah Ryobi battery would do the job, assuming that the cranking battery was not stuffed? Thanks

[LRD414]

.... bit more information as to exactly how you connect up the Ryobi battery to the cranking battery .....
It’s in the sketch I put a few posts up.

I have a Projecta lithium jump starter which cost about $200 and works just fine. Recently I used it to start a car whose battery was totally flat. I connected it, left it connected for about 10 minutes and then the car started. This was in Glen Innes in freezing cold weather. It also starts my Defender no problems.
I love it. It's compact, powerful and can charge phones and run LED lights. It lives in the drawer in the Defender. Great stuff! Buy one, you won't regret it.

[4bee]

This is another interesting & informative thread that while not having a need for a device has puzzled me how a stupidly small battery can start a car with a flat battery.
Minds eye I could only imagine an exploded battery & not having gone into this previously didn't realise it was only a surface charge that was being used & not the Lithium battery as the main cranking battery. Deeeeerr.[smilebigeye]

Thank you for this thread.

It also means I need not carry a 500 km extension lead back to my shed to use my normal battery charger.:Rolling:

BTW, this thread seems a hell of a lot easier to follow than Wiki wottsit.

Here's a picture of my Projecta lithium starter. I put the roll of tape there for a size comparison. They come in several sizes.

I got this one as a freebie when I bought an iTechWorld 5KVA generator last year. They’re about $200 as a stand-alone purchase. Incredibly versatile gadgets. Had an earlier version a couple of years ago which started my TDV8 4.4 L322 easily. This one will also run my 40l Engel for several hours. Amazing bit of kit.

Same unit as my old man has that I mentioned up in post #7

[DiscoMick]

Looks similar to mine, just different colours.

[BradC]

Aside from having a high energy density, lithium cells also have an extremely low internal resistance so they can supply lots of amps for a short period. They have an extremely low rate of self discharge, and I've only seen two go up in smoke. In both cases they were the switching MOSFETS rather than the cells themselves.

The problem with these units is they don't have any current limiting outside of the inherent resistance in the semis, the cables and battery clips. So if you really do have a duff battery and the stars align you can certainly let the smoke out. Admittedly it's hard to build a reliable current limiter for a couple of hundred amps that'll work more than once.

That said, if I was heading into the middle of nowhere, I'd have 2 of these in the box right next to the water bottle and EPIRB.

The projecta seems to be the answer. Beware as the local SCA outlet did not seem to know a lot about it so now I am off to Repco. Thanks again for all the help.

[DiscoMick]

They come in several sizes so make sure you get one that is big enough.

[BMKal]

I’ve had mine for more than 5 years now and had to use it recently for the first time in three or four years. Started a HiLux diesel that was struggling to turn over without a problem.

[4bee]

They come in several sizes so make sure you get one that is big enough.

So what would the recommended size be to start a 2Litre petrol? They seem to vary from 800 to 1200 from what I can see. A good size but not an overkill?

Guess who had a flattie yesterday but was close enough to a power Point & my 240v charger so no real drama? This time.[bigsad].

depends on petrol what.....

IVe had one not want to start a series III 2.25p but would wind over a newer td5 happily.

these things deliver the amps they advertise for just a few seconds and they shut down on low voltage.. its the delivery curve that makes them work they stay on a high voltage for a relatively long time and then drop off quick.. as opposed to a traditional lead acid type battery which has a comparatively linear drop off rate.

[4bee]

Thanks Dave. So the answer is..... The biggest you can afford, roight?

Reading on from my initial post they do seem to be the Dog's Danglies & work more often than not.[smilebigeye]

This is a larger size:
PROJECTA LITHIUM JUMPSTART BATTERY PACK 1200A 12 VOLT FOR DIESEL PETROL IS1200E (https://www.autoelec.com.au/projecta-lithium-jumpstart-battery-pack-1200a-12-v)

[Albert]

I have a SJS branded one. Have used it many times over the last 4 yrs.
Its size is 600A and claims to start 4.5L petrol and a 3.5L diesel.
I have started my 4BD1 county with a very flat battery and used it at least weekly for a year to start my dead flat tractor until i got a new battery for it.
I'm sure the newer one would be even smaller and better now.

[Kidbeen]

Do these jumpstart units get replenished with a 240 volt charge?

[matti4556]

Do these jumpstart units get replenished with a 240 volt charge?

The Projecta one has an included 5 V USB lead included for recharging. Any 2.5A-ish USB outlet will recharge the unit.
The work lamp function can also be set to flash SOS as well. Nifty feature if your trying to get someones attention that understands morse code!
Matti

[DiscoMick]

The Projecta one can be recharged by either 12v or 240v.
I notice Autobarn has a SJS 1200 amp lithium jump starter for $169 in its latest catalogue.

i had one of these. was great until it failed after 3 years. not worth the price for 3 years imho

nope,

the best quality one you can afford.

1200000000 amps is no good to you if it cant get past the 25 amp rated clips with the dodgy spring.

[4bee]

The weakest link eh.

I take your point, not much chop if the ****ty pressed clamps don't pass rhe current without distorting or even melting.

So no online purchase then, a visit to the retailer is a must.

not really, you can shop smart and get it cheap online and still get quality...

I have a 5KmAh qi charging battery bank that everyone laughed at me for buying because they were buying 20KmAh ones for the same price.. funnily, the both look almost identical mine weighs more and has a 6200mAh battery in it and theirs has a 4800mAh battery. Mine can charge a phone (via usb or Qi) while the unit is plugged in to charge at the slow 500mA rate and when the internal battery is charged switches up to the high rate as well as auto switching the internal battery to charge things if the charger cable comes out of the tank or the power dies. the 20K units cant charge while being charged, cant charge through USB or Qi while plugged in....

the simple rule applies, if its too good to be true it probably is...

f you're interested Costco have some good units and the aldi one that comes up does quiet nicely but it wont crank a heavy start engine from a dead (or missing) battery (as per the previous posts) It is a fantastic little bank for camp phone charging, works well with their small solar kit. The aldi one will start an Excel with no battery.



side tip.

for those who have glow plugged engines with delay start... The jump packs will sometimes give up on the glow plug cycle if you have a dead battery, if you disconnect all bar one glow plug (you'll get fault codes on a modern diesel but they typically dont inhibit engine performance too badly and limpings better than stopped) hold it pinned and give it a crack you'll usually get it to running.

[DiscoMick]

I thought $215 for the Projecta one I linked to above was reasonable and it's good quality.

[iannicki]

On sale at Aldi on Sat 28 Dec 19 for $80: Jump Start Powerbank - ALDI Australia (https://www.aldi.com.au/en/special-buys/special-buys-sat-28-december/saturday-detail-wk52/ps/p/jump-start-powerbank/?pk_campaign=au_product_newsletter&pk_kwd=2019-12-23_11-46)

Just in case you are new to this forum and have not seen the evidence provided by my previous posts, I don't know anything about anything. However, the Aldi option was mentioned by Dave in a previous post; and maybe someone who does know something will let people know whether the Aldi jump starter would be any good for the various D3/D4 engine options.

Ian

[PhilipA]

Aldi have them as special buys next weekend.
Would like to give more info but SWMBO chucked out catalogue.
Thye say it starts a 2.5 L diesel.
Regards PhilipA

For the cost of one of these lithium jump starters you can get a pretty decent 120w solar blanket that will charge a flat battery up enough to start the engine in 15-30 min depending on how much you are willing to spend on the blanket, They are also bloody usefull when camping as well.
Most of the blankets can fold away smaller than a charge pack in its case and there is little difference in weight as well.
I have bought a few of these starter packs over the years and all of them have struggled to start a V8 (Diesel or petrol) even when brand new and fully charged, After about 12-18 months the chargers are knackered but still can proove usefull to charge a phone or a camera.

I have a solar blanket but they don’t work at night or very well on heavily overcast days. Even if sunny you might not have the time to use the solar blanket if you need to say, catch a ferry at a particular time. I used my lithium jump starter this morning. My intermittent battery drain has raised it’s ugly head again. Vehicle would barely turn over. Out with the jump starter. Back in business. Getting on to 2 years old.

[DiscoMick]

Love my lithium jump starter.

[sharmy]

I used mine once on a 3.2 ltr bt50. it just started it so I was happy,I put it away under the front seat(in its plastic case) and when I went to use it a couple of months later it had swollen up and was useless. I am lucky it did not explode.

Mine lives in the driver’s door pocket. Days up to 45C parked in the sun. I may be lucky but is could be a quality issue. Mine costs between $250-$300.

This is an interesting report on how to maximise the life of lithium - ion batteries. It seems to require quite a different approach than for lead acid batteries.
I've been trying to get my head around this to figure out how to prolong the life of my mobile phone's battery, which is already 3 years old. I also have a Projecta lithium jump starter, which is great.
Some tips I've worked out are:

Don't deep discharge the battery as that shortens battery life.
Aiming for about a 70-80 % discharge down to about 30% seems to prolong battery life.
More frequent charging is better than occasional charging.
Don't leave the battery on a charger for more than about 12 hours as that can cause the battery to overheat (this 12 hour figure came from the instructions for my phone).
Hope that helps.

Instead of spending $200/$300 on a jump starter wouldn't it be more prudent to spend that money on a decent battery and ensuring that the charging system is working up to spec??, This would eliminate the need for the jump starter in the first place[thumbsupbig]

I bought the ones that I have tried primarily to use on my boat as I spend quite a lot of time at sea in remote areas that it is a rarity to see another vessel and in many areas I go the VHF/27Meg reception is very patchy or non existent.
I tested the units by having them fully charged and stowed away for a couple of months then I try and start the engine 70HP or 115HP 4 strokes with a half flat battery fitted (wont spin the motor on its own) and I found that 9 times out of 10 they did the trick.
This "Fine" if you don't rely on these chargers as your primary "Back Up" But that 1 in 10 failure rate can get you killed in a boat or even if you are stuck in the middle of nowhere with your 4WD with No help available.

Battery "Maintenance"( dual batteries and an isolator switch fitted is a MUST on boats) and maintaining the charging system is MY Primary defence against flat batteries on my boats AND my 4WD's.
As I always carry at least 1 solar panel either on the boat or in the 4wd I use these as my secondary line of defence I case I do something completely stupid by leaving something on that flattens a battery or even both of them overnight.
Even on an overcast and rainy day a decent solar panel WILL put enough charge into a battery to get you out of trouble [thumbsupbig]

In the City or suburbia these starter packs may be useful But NEVER rely on them 100% in the unhappy event of getting a flat battery Especially in a remote area.
Personally I can't be bothered carrying one of these anymore and they have been delegated to a shelf in the shed with all the other things I have bought that I though were a Good idea at the time and have been disappointed at their usefulness and are slowly gathering dust.

[DiscoMick]

I certainly agree with you that maintaining the charging system is the top priority, but I do carry a Projecta lithium pack in the drawer in the Defender as it doesn't take up much space.

.

Agree, to date I haven’t been tempted to buy one.....I don’t even carry jumper leads.

I replace batteries well before there due, i choose a battery Isolator that isolates the starter from the AUX as soon as you turn off the engine....in saying that I have run permanent solar since way back before it become popular.

Over the last 30 day the lowest my Aux has recorded is 12.45v and that’s running a fridge 24/7 complete with a black roof closed up on very hot days. Easy to jump option without cables or jump start packs.

Suppose with all these modern cars packed with computers and choosing use the starter to run accessories one might be tempted to have back up.

Sounds like time for a huge Garage Sale, Trouty old boy?

[rick130]

I bought one a few years back in Ulladulla as a mates kids had left the ignition on in their people mover, I'd just acquired the Disco and you can't clutch start an auto.
I can't recall if I was in the Disco or the work ute at the time, but the jumper leads were in the Deefer back in Canberra and I didn't have the facility to jump from the second battery that I had in the Deefer.

Used it once since, worked as advertised.
Plug it in once a month

You can deep discharge as much as you like and it has no measurable effect on battery life, although if it's a multi-cell battery then you are reliant on the protection circuitry to cut off prior to cell damage. Pretty much all of them do. If you want to extend the life then you don't fully charge. 80% seems a good tradeoff of life vs capacity. A number of electronic devices have a battery preservation mode where you can limit the charge capacity in exchange for a longer life. My old 2006 Vaio was the first PC I had that did that as an option. I had 3 batteries in the life of the laptop and anecdotal evidence was it worked. I've heard some of the phones offer that option now also.

You could describe it as a Lithium battery has a life limit of supplying X number of Ampere hours. If you do that over 200 full cycles, or 2000 short cycles it's not really that much different, but they do tend to age faster if you charge them to capacity (resulting in fewer cycles).

If you want to store them, discharge them to ~40%. Put them in the fridge. Heat and a full charge are the enemy of Lithium cells, 40% seems to be the value where they age the slowest. Over discharge will kill them quicker plating the electrodes and potentially causing catastrophic failure when you try to recharge them. In this context, over-discharge is past the point the BMS would have already disconnected the cell, so it's not something you can do deliberately or accidentally. This is the reason they have protective circuits to prevent over-discharge.

You can leave them on the charger as long as you like. Chargers for Lithium batteries cut off when they are called "full". Trickle charging kills them.

Frankly without the protective BMS, Lithium batteries are spawn of the devil. The role of the BMS is to prevent them going off in your pocket and setting fire to your grundies.

The electronics have now evolved to the point where a lithium battery (one or more cells) is a robust, mostly safe and usefully dense power source. It does take the electronics to keep things in check though.

I would love it to be that simple for me. I have an intermittent battery drain that can disappear for months then come back without warning. I’ve tried to find the cause. I have had two auto electricians look into it with no luck. I have a solar blanket and can jump from the lithiums behind the rear seats if I had to, but the jump starter is the quickest and simplest solution. It hasn’t let me down yet.

[iannicki]

Lithium jump starter bought from Aldi. Here's hoping to never having to use it; but if I do need to, I'll report back.

In the meantime, if I ever I get the urge to go for a 2-week bike ride without access to 240v power but in mobile reception range, I can keep multiple mobile phones charged!

[ozscott]

Got a Noco GB70 to replace my cheaper jobbie that puffed the battery when I cranked my D1 a little long (No circuit doing any temp sensing etc).

The Noco has an impressive build including electrode jaws 3 times the size and thickness as the old one. Good kit.

I bought a Projecta 1500 amp unit
It failed after a 300 tdi start
I have since gone to Repco capacitor starter and it’s been a much better thing
