Battery surprise.
Yesterday I removed 2 group 31 gel cell batterys from my boat. They have been in it since 2003. The boat has not been used since 2006 but the batterys have had a charge from time to time up until 2012 when they were last topped off & put back in the boat.
They have been almost 18 months completely unattended. No maintainer charge. Nothing. Thought for sure that these 2 would be toast for sure, if not from neglect then from simple age which is now probably over 12 years from new.
One at a time the were put on a multi type, multi stage charger. One took overnight to recharge. The other only a few hours. Put a load tester on both. Both test almost as good as new recovering immediatly after load release.
There is something to be said for gel cell technology even if it is pricey.
