Riva 55 battery. (for 510)

[Glennie]

Hi,

I've just had one o' these monsters delivered!

It seems to take an age to recharge using the 510 USB charger.

I'm hoping it's just 'cos it's so dam' big, or is there something more sinister?

I'd hate to think there's any kind of incompatibility and I've bought the wrong thing.

Please put my mind at rest!
(or tell me the worst!)

Regards,

Glen.
