Accupower if fine.

Go with whatever charger you want, makes little difference.

A fast charger might reduce the life of a battery by 10-20% , but who cares ?

$10 buysa new set whenever you want.

Hi , all ! In my opinon , you should choose :

- NiMH batt with 2300 - 2500 mah . The batt life will be longer and the self discharging will be lower . I used NiMH 2700 mah anr 2500 mah batt Sanyo . The self dicharging are 1% for 2500 mah and 5-7% for 2700 mah ( per day ) .

- Smart charger with individual charging circuit for every battery and refresh funtion . I think , you should buy packed set ( smart charger with NiMH batt )

- Smart charger manufactured by Sanyo , Fuji , Energize ... All are big names . You can use those smart chargers without worry .
