So we had a unit, that was tripping. In sense that it would kick
constantly too on battery then off an back on. I thought that the
battery needed changed so I took them out for testing and came up 13
Volts rated at 12 Volts. The machine they were connected too indicated
that the battery should be changed. I reconnected them then and thought
that they needed charged but, now the unit itself won't come on and
been about 1 - 1/2 days.
