12V Interstate Deep Cycle Battery shows 16.9 Volts
I had my trailer hooked up to shore power for a couple days and now unplugged it. 4 hours later my DC plug in the trailer shows 12.75v. My 2 interstate batteries showed 16.2 after unhooking and 16.9 volts 2 hours later! Typically they are closer to 14.
Now I am about 4 hours after unhooking it and the batteries are at 16.9/17.1 Volts.
Batteries are same age Interstate SRM-24
What could be causing that to read so high? I have multimeter set to 20v DC.
Could low water levels cause that? trailer is 6 months old how often do you check the water. Is it "explosive" to pop the cap to check water level right after charge with reading that high?
