Nokia 6120 battery capacity

My 6120 has a standard 750 mAh battery in it,
Is it possible to buy a higher capacity battery that will not damage
the phone? I have seen some mail order companies advertising
apparently compatible batteries of 1000 mAh but when they arrive they
are only 650 mAh so I returned them for a refund.
The 6120 uses a BL-5B battery.
Can someone please tell me just what is available?

Thanks
KC

A battery that truly has measurably higher capacity is likely to be
physically larger and unable to fit inside the phone. Some phones (e.g. LG
models) offer optional battery doors to accommodate the extra thickness of
a higher capacity battery.

If you're running out of power, try a spare battery and external
battery-only charger, and just swap when the phone goes dead.
