Re: Battery Question
Spare Parts you are sounding good with your battery knowledge, except there maybe help for a battery with a lower cell volt reading.
If you happen to get a cell a little lower then the rest you can try to discharge the battery over a couple of hours with a small load like a spot light and the put it on a charge with a higher current at around 14.5 - 15 volts. You may have to repeat it a couple of times but it will help to remove any sulfate that has built up on the plates and regain the surface area.
Sometimes just a equalizing charge will help if the battery isn't damaged to bad.
You need to keep in mind that the above process will shorten the remaining life of a battery, but if it is close to being replaced any way who cares. This will only help extend your battery for maybe a season.
One of the easiest ways to protect a battery is to install a battery minder. You need one that has enough amperage to maintain the charge of the battery and yet be able to reduce the charge low enough not to cook it when it reaches full charge.
