In May of this year I got 6 of the Interstate 6 volt wet cell U2200 batteris and installed theem in the boat, They have been working fine up until two weeks ago.
I have them installed in sets of two for a 12volt system 3 banks and another bank of 12 volt walmart starting batteris.
About two weeks ago the batteries changed in the way they take a charge, before I could set the charger
on 15 or 20 amps and within a few hours be fully charged. Now I can not set the charger
on amything higher than 2 amps if I try to charge any higher the charger gives a code 005 meaning batteries over heating
so it takes days to fully charge them now.
In then past I have always left the charger on and they would float then charge.
My question is; Should I be draining them to a lower point before charging
I have tried a new charger and get the same code. So it is not the charger, Also two days ago I took the boat out and ran the motor
7 hours so they should be full any way. I have tested the Alt and it is working fine.
thank you for any advice or info.
