    When I put a digital Multimeter on this battery what figure should I get for a fully charged battery?

    Any help appreciated.

    12.7v, after the battery has not had any form of charging (driving, solar etc) for at least 5 hours.

    Unless you have a recently calibrated voltmeter, don't worry too much, it's doing all you need of it.

    Thanks.

    So I need to disconnect the battery completely, the solar panel will be giving some power even this time of the year, and then check after 5 hours.

    Is that right?

    And if it doesn't reach 12.7v at what point should I get really worried?
