Customer Reviews

A battery with a bit of a bug
Battery good, no problems! However using proper charger means occasionally it flashes red and refuses to charge. This can be cured by "jump-starting" (+ to +, - to -) it with a 9v battery for 10 seconds or so - it puts enough voltage into it to allow the charger to recognise it and charge it properly (solid red light for ~90mins). Batteries may explode if short circuited so the author takes no responsibility for the actions you may choose in this method!

A good battery that sometimes has problems
The Casio NP-20 is an incredibly small, thin battery that provides great performance for compatible Exilim digital cameras. That is, when it works properly. The problem with this battery is (or can be), that it can suddenly become un-rechargeable for no apparent reason. This is indicated by a flashing red light in the compatible battery charger (Casio BC-11L) when the battery is inserted for recharging. The one good thing is, these days you can often buy a replacement original Casio battery on Amazon used for $10-$12, instead of the original $40 or so for a new one. I've bought several used ones that work as good as new, although I've also had one or two with the "flashing red light of death indicator" as well.

The best deal
This is the original battery for my camera. If fits perfectly unlike the clone battery I purchased elsewhere. I think that for a digital camera, always buy the original battery. Go for the real deal.
