I received some Energiser 2450mAh AA batteries (together with a dedicated charger).
They have been charging for ten hours now (at 280 mA).
As the charger is consuming 7 watts, how much is it costing?

(I know we have an electrician in our midst.)

Do any of you use rechargeables and how long do they take to recharge?

My other rechargeables are just 850mAh (for my pocket radio) and they don't take as long . . .
