Riva 1100 Batteries

[CupCake]

Hi

For nearly two years I have used Rivas (from the same supplier) and they have been great. However, my two most recent ones have decided to play silly buggers while charging up.

The light turns green after about an hour and in order to get them fully charged, I turn the charger off, unscrew them, then reconnect and they start to charge again (red light showing) . This happens 2 or 3 times during the charging process. I've tried different cables but it still happens. Once they are charged, they are fine.

I clean all connections regularly.

Anyone had a similar thing or any idea why this happens?

Thanks
