If i put different accumulators in a different recharger it will explode? ?

I have some accumulators for my RC Toys(plane,helicopter,car).They are DURACELL Rechargeable 2650 mAh.And the accumulator recharger is GP Power Bank for NiMH 2700 mAh which recharges the GP NiMH in 6 hours.Because they did not have at the store GP NiMH 2700 mAh i bought DURACELL Rechargeable 2650 mAh which were the closest and the seller said that there is no chance of exploding!It's true?

True; if the charger gives slightly more current (ie 50mA) this will have no ill effects, you won't necessarily notice any quicker charge time either.
