hi I'm about to buy a couple of sets of nimh rechargeables. at the moment i have one set of 1100 mAh, i am looking to get larger capacity sets ie 2500 mAh's. will these be ok to charge in the charger i got with the old batteries, or do i need a new charger.. the charger states...(1.4v--250mA 0.35va)
