Evening All,
               We have 2 x 12v "truck" batteries connected together then connected to an inverter which we charge off a genny/battery charger daily ,after a few hours of charge I let them rest for an hour or so then test the charge with a voltmeter thingy(2 pos/neg spikes) - if it tells me 12.7 or so I'm happy. Is this the wrong way to do things - should I leave them on the genny for longer-let them rest for longer - what should a full charge read.
                                           Ta,
                                               Briand.
