Would a new battery be an option if this one is failing? I could take it n get it tested for faulty cell.

No battery will ever read 13.8 volts if left for several hours after charging for the true voltage to be obtained.--Even with a brand new battery it's highly unlikely to read more than about 12.6 or 12.7 volts.

It's probably not the battery that's failing but the way in which you are testing it.--

There are 6 cells in a battery.--Each one will give about 2.1 volts.--( six times 2.1 is 12.6 in total. )


If you would like to read a bit more about batteries then go to the thread on the main page that says---Really, really useful information.--I have three posts in there about batteries and their funny little ways.----Go have a read under the name of COLVERT.
