I have a sealed lead/acid 12V rechargeable
battery that I use to power my spotlight. It should provide about an hours use
before going flat but it conked out after ten minutes and I wasn't able to
recharge it.
I took it back to Battery World and they
found no problem with the battery or the recharger. After a long
conversation with the very helpful salesperson I discovered the plug in recharger will not or will have trouble recharging
the battery if the charge in the battery has less than about 10 V charge
remaining. This means that once the
spotlight starts to dim it is wise to stop using it and recharge the battery. I
had run down the battery thinking the battery had "memory". I know now
that this concept only applies to nicad type batteries.
Battery World were able to fully recharge the
battery so hopefully there will be no further problems.

PS Battery World can supply a battery
with "cigarette lighter" adaptor and carry case for about $80.
