rechargable AA batteries

[weeds]

they are for my digital camera

the orginal sony ones are quite good however the dick smith ones never hold there charge for very long just sitting in the case they loose charge much quicker than the sony

what brands should i consider

[incisor]

sanyo and sony are all i have found to be of value.

i have tried many brands including the cheapy green ones on ebay and the sanyo and sony are the only ones to last more than a few months..

i have given up using them in my camera, i use the blue and silver lithium units now, way less problems.

those ones in particular for AA's

Ignore your cameras low battery warning thing..

Nominal voltage for a NiMH rechargable battery is between 1.4 and 1.2 volts where as the standard alkalines are 1.5-1.1v (from memory) so your low battery warning will come on early but should stay on longer...

Get a decent charger for them tho the biggest problem is the batteries not getting a full charge of the cheapie chargers, or being overcharged and cooked.

[incisor]

my experience was the lower voltage affected the quality of the pic.

hp945 5mp camera and a canon 3.1mp camera, had a good quality charger that got the batteries to their rated voltage. first signs were minute waves in the pics and odd pixel corruption, not visble till you zoom right in. the warmer the day the more it affected the cameras.

have noticed the same thing on my mates olympus so it wasnt something to do with my gear, it is a quite wide spread problem...

[Blknight.aus]

never had that problem but then I dont take high enough resolution pics for it to be a problem...

I have a 4mpix camera and I shoot at the same resolution I used to when i only had a 2. The main benifit being it shoots so much faster.

I have 8 Energizer 2500mAh AA batteries that I have used for over 2 years. They hold their charge well. I think that they were around $20 for 4.

[Quiggers]

Same as barryj. Works fine for me...

Interesting as I was going to say just the opposite, I've had problems with the energisers dying, but no problems (so far) with Fuji batteries.

I have found that the newer digital cameras are so much less power hungry that I have not felt the need for rechargeable batteries - but to some extent this depends on how many pictures you take. As pointed out the rechargeable batteries are lower voltage than alkaline ones - how much of a problem this will be is camera dependent, less obvious though is that their capacity is a lot less.

I suspect the life of rechargeable batteries may also be very dependent on the charger you use, and the charger/battery brand combination may explain why people get different results from the same batteries.

Since I got my digital camera a few years ago have had nothing but problems with rechargables, regardless of the brand name. They al clai to be perfect for certain applications but that isn't the case.
For example last year when we travelled overseas, our first stop was rome, first day the vatican the two sets of batteries I had taken and charged up the night before, both went flat after about 40 photos, had to resort to taking lower quality photos with the digital movie camera.
Anyway we found a post card seller nearby that was selling a card of kodak batteries(non-rechargable) plus two for free, 6 all up. 4 batteries lasted us, 5 weeks, and over 300 photos, the remaining batteries i took to the falklanda and they lasted for two weeks, Now I only buy nonrechargeable AA's on a card, usually about 10. They are much more reliable.
Especially when you are travelling.
Now I have 2 rechargers and one with a 12 volt adapter that is about as useful as an ashtray on a motor bike.

When we got our camera they told us for best use on digital cameras to use "Nickel-Metal Hydride" batteries, they are suposed to last longer or something like that, we got 4 and they seem to last, when we use the camera.

[FenianEel]

I have Fuji, Arlec and Duracell.

Never had a prob with Fuji, seem to take heaps and last ages.
Duracell I've only used & recharged once, didn't seem that flash
It may be me, but the Arlec's seem like gobsh*te to me, as does their charger.
Anyone know anything about them? I thought they were supposed to be good gear, but their name may be better than their batteries.

[Quiggers]

I used to have heaps of Arlecs for other thingys, fenian, but they've only lasted 2 years or so, before swelling and leaking. (weren't real good in holding a charge, either).

The other rechargeables I have for the camera are 'Grandcell' (NiMH) which work fine and last longer than the Energisers.

But when they drop to below what the camera can take, volts wise, I shove them in a torch and run 'em down, so they get a full charge every time....

Someone from the past said - you can't charge a half charged battery - due to the battery memory effect - true or an urban myth?

On advice from a mate we bought a Varta fast charger with 4 AA batteries a while back. They last just as long if not longer than the expensive high grade lithium throw aways, but pay for themselves fairly fast. I have two sets of 4 batteries and they run rotation in the camera and the UHF handhelds. They charge in 15 mins and the charger can be run off the cig lighter. Not cheap to buy at about $70 inc 4 batteries but worth every cent. The only shortcoming is that they die without warning whereas the lithiums or alkalines give a little warning with the "flat battery" light on the camera.

Go get some!

[Andrewpv01]

From what I have read batteries don't reach their full charge until after 2 or 3 charges/discharges.
I don't use them often enought to check on that though;)
Once mine are charged, usually the night before I want to use them, I just run them down until the camera stops.
I now have a camera that takes 4xAA's and have noticed that makes a huge difference to the old one that only took 2 batteries.
