get those that are able to hold charges longer like eneloop type. i think most brands have already came up with that technology.
conventional nimh have higher capacity (up to 2700mah for now) while the eneloop types is about 2000mah. but u don't need to remember to charge it up to full the night before to have the best performance from the battery.
i choose an option of both.
8x sanyo eneloop.
the eneloops are backups. while the conventionals are the ones i always used. Though i haven't forgotten to charge those yet. Which is a good thing... being prepared is always good.
Went to Infocomm shop today, the charger for Powerex is sold out. May I know how much do you all pay for it and where else could I get it? And does the charger takes in four AA size batteries or more? Thanks.
