Garmin 810 charging problem

When I plug the 810 into with the computer or the mains it is recognised by both but instead of charging up its using up the battery at a quickened rate.

Tried various garmin cables and chargers all with the same outcome. The unit hasn't been used since September last year as I use a 510 day to day and the mapped unit for touring.

Any ideas?

    Well if you've tried different cables then it must be the 810 then. How old is it?

    You could try a factory reset.

    Maybe try letting it die (go flat) and then recharging from empty?

    Sometimes the battery state can get misinterpreted by the software. My old 500 spent most of its life at 100% battery, but if you let it run flat it would fix it temporarily

    This and let it go flat.

    Agree with letting it die but also check the cable socket is dry, any moisture or gunk could cause an issue.

    Reality: battery is probably toast. Replacement is £15-20 if you DIY (videos on YouTube to help you out in the replacement process).
