I have just bought an electric drill/driver.
The charging unit has a green light on - I assumed that it would go out when charging complete.
Not the case at all - from the handbook :
- The battery charge indicator is not a charge-control indicator. The lit indicator signalises the flow of charging current.
The charging procedure is not ended automatically.
A temperature increase of the battery indicates that the battery is fully charged.

Well there you go - when it's hot - it's done !!
