The mentioned Eneloop NiMHs are rated with typical capacities of 800 mAh (standard type) or even 950 mAh (Eneloop Pro). So you can expect about twice the original operating time.

Even better still - I bought some Eneloops a few weeks ago, and the spares on my desk, labeled BK-3MCCE, are rated at "1.2V min. 1900 mAh (HR6)". I haven't even had to recharge them yet.
