They have been off charge for a few months but have a resting voltage of 12.8 to 12.9 volts. If I don't install them in the next few weeks I will put a trickle charger on them.

A battery observation that I made yesterday. I own/operate heavy equipment and noted a weak 12v battery yesterday in a D3 Caterpillar Bulldozier. Exposed the battery and found it to be original caterpillar battery 16 years old. Recharged it and waiting to see if I can get a few more years out of it.
