Do lithium rechargables come in AA? That’s what my camera uses (and most/many others). It’s common with all the other batteries in my life, so I can swap batteries with everything else. Also, if you in a remote location (I travel a lot) you can almost always get AAs. If the lithium rechargables are non-standard, I’m out of luck.
Some cameras come with non-standard sized lithium rechargables, but not a seperate recharger. That means you have to use the camera to recharge the batteries, which is a pain if you want to swap batteries and recharge the spent ones at the same time. I believe (no facts, I can’t find any recharges online) that there aren’t many recharges for non-standard (AA, AAA, D) batteries.
http://www.thomasdistributing.com/nimhbattery-faq.htm is an excellent FAQ about NiMH batteries. For $32 you can get an excellent Maha recharger (with 12V car adapter) and a set of 1600 mAH batteries.
My camera (Olympus D-490) came with non-rechargable lithiums that I will keep as an emergency backup since they won’t lose their charge. But all the camera users recommend NiMH as the only real option.
