Do batteries really explode? I've seen warnings on almost all kinds of
batteries saying if you put them in fire, recharge them, put them backwards, or
open them, they could leak or explode. Is this true or are they just being
conservative?

what happenes inside the battery when you recharge a non-rechargeable battery,
like alkaline or lithium?

Hey, I stole about 10 recycled battery packs from Radio Shack today and
discovered that most of them simply had one dead battery with the rest being
quite fresh ... pretty amazing ...

I charged some AA batts in my charger, they've gone flat before Ive even used
em. Is this normal. They're Sanyo cadnicas nicd circa 1983. Shall I chuck em.

Does anyone know a good UK supplier of Kokam LiPoly batteries?  Failing
that, does anyone know a supplier who will ship to the UK?
I'm especially interested in the following batteries:
The 2.7Ah SLPB 436495 and the 11Ah SLPB 55205130 (both are 3.7V).  I need to

I have been having problem with my digital camera turning off with
half full (or full) batteries when they have been lying unused for a
while. After trying cycling and finding no big difference I assume the
problem is short term self discharge.

Can anyone please impart some of their knowledge regarding Inverters
and hard-wiring an inverter into a caravan or boat.  My knowledge of
inverters is limited to simple set-ups (Battery -> Inverter -> AC
Load).

I have car battery which hasn't been used for like 4 years and it was in
very good working condition
Will it work perfectly if I will recharge it?
Lets say I will use 6amp charger or 10amp, what would make a difference?

Hey, why don't they start installing Didoles in non-rechargeable batteries to
prevent greedy people from trying to recharge them?

You know how the terminals of 9-volt batteries have clips on them, so you can
connect them in series.
Connect about 10-20 of them in series and touch the end terminals.
Good luck!
