...than the instructions list? The charging current is 100 mA (AA size) and 1300mAh, 1600mAh and 1800mAh charging times are given (16, 22, and 25 hours). We recently purchased 2450mAh AA batteries. The long charging time is no problem, but I just need to know if it would be safe to use this class 2 charger for these batteries and approximately how much time it would take to charge them. Thank you to anyone who might be able to help.
