Alternator Capacity

there is a "dual battery" system that you can install in your "any flashy car you like" without voiding your warranty.

However all it has in common with a proper dual battery system is that yes, it has a second battery in it. These are also marketed as a "battery tank" or "portable 12v power source" most of these are little more than a 12v SLA battery out of something like an emergancy exit light or in the more expensive models cases an electric wheelchair and have a cheep and cheery cigarette to cigarette socket cable to charge them and usually come with the proviso that, no you cant charge them and draw power from them at the same time.

I'll admit to have had a couple of these and found them usefull for running small lights or 12v accessories for a short period (matress inflators, phone chargers, dvd players, the shower water pump) but the ones that are nice and easy to carry around generally dont have the legs and the bigger ones that have a really useful charge span are just to big to be lugging around for small jobs.

Wilbur, if your not going to back any of your claims, so be it but keep on subject or go elsewhere.

ok, now Im curious.

Quite simply, drivesafe used his power to remove my post that he didn't like. I hope you get to read this before he again exercises his power of censorship.

If you would like to know what I posted, please PM me (assuming drivesafe doesn't also block that) and I will send you a copy. Anyone else may also PM me if they want to see the post.

Rgds,

Paul

actually, I just read your original post...

I never called you stupid, I just said that sarcasm is my defence against stupid.

I've also just re-read the thread. I mentioned humour in one of my posts towards you (and at the time actually ment it as just that)

The fact that you drew the conclusion that you were called stupid was your own perception.

potentially the most insightful thing you put in this thread. I just regret that the original post was deleted so no-one else can witness you conducting a SPWOSO

Take care Wilbur, your on thin ice and while others have seen your post and recommend you be band, I’ve given you one warning.

Your post had absolutely nothing to do with this thread and was nothing more than intended abuse.

Your post was way off what is acceptable/tolerable on this forum.

Again, Wilbur be warned.

OK folks, back on subject!

If dc to dc chargers were better at charging, surely a d4 or rrs would already have one lol :wasntme: i have a n70 in the disco that is very old, a very tiny deep cycle which is also old, i use a redarc and never had any problems, and the battery in the van is always charged to, it is run from the second battery, dunno if i have it hooked up right but it works like a treat running 2 fridges all the lights and gizmos in both the car and van

Paul/Wilbur... You main argument seem to be that there are a number of (reputable) companies that sell DC-DC chargers, so they must be needed.

If we take that argument, then reputable companies would not manufacture/sell devices such as "performance" air filters; turbo timers or other such devices which have no practical benefit on a road vehicle or 4x4.

You have posted no evidence to support your claims.

All the engineering papers I can find on DC-DC converters are for 12-14/40 volt systems (bar 1 which does not list voltages). There are plenty of happy customers out there with conventional chargers. Maybe their batteries only have 94% instead of 98% charge, but would they know or care???

Most of the members of this site have no allegiance to drivesafe, but we do generally have good BS meters.

How about posting some evidence??? (if you wish to be taken seriously).

double post...
