after 48 hrs charged batteries still read 13v
« on: May 11, 2019, 01:50 AM »
A fully charged battery should read 13+volts right after charged. But after 12-24 hrs it supposed to settle down to 12.7-12.8 volts. I have 2 Exide Nautilus Marine DC27HDT bats from Rural King, 1 is 10 mths old the other is 1 mo old. Is there any reason they still read 13.04v after 48 hours, will this damage them. Or do I have a bad charger that's overcharging them, it does shut off when they reach 13.2v.

I think it's just new and fairly new batteries. I just put new batteries in my golf cart last October. 12+ hours after charge, they are holding a full volt over the normal voltage. They will lose capacity over time. Meanwhile, enjoy a bit of extra power.

tks for the input thought maybe my charger was overcharging them. I've had it for years and it got rained one time, after that I always wondered if getting wet would cause it to malfunction.
