ok, i have a fuji digital camera that came with an overnight charger and some 1800 mah batteries. it says to charge them for 12 hours.

question 1: if i get batteries of say 2500 mah do i need to charge them for less time ??

question 2 : i got some cheap 800 mah batteries, but the charger says to use 1600 mah or above, will it harm the charger, batteries to use 800 mah

any tips appreciated

anyone anyone ???????

1) no, they'd need to be charged longer.

2) Don't bother, they'll run out in 5 minutes flat. A false economy.

would 2500 mah last a lot longer than 1800 ?

does anyone know where i can get some cheap ?

Yes the 2500 ones would last longer than the 1800.

Cheap ones can be bought from 7dayshop (they do their own brand).

2) 800 mAh batteries are probably AAA ones... unless they are very old/naff!

800mAh tend to be NiCD.

2100mah half price £4.99 in maplin at the moment.
