There are many things that KILL any battery. BUT...One thing that kills more batteries than people realise is, Over-charging. And being winter is upon us means a few of us take the batteries out of our ATV's and put them on a charger.
If you do this? Make sure you have the battery cells filled up (and the Battery Manufacturers say not to use more acid to do this) Use distilled water unless there is some other type of water the Manufacturer of your battery specifically says you should use. The distilled water I said to use is what I've always used, it doesn't mean it's the best or only thing to use. The way times change, there may be something newer and better. I don't know?
This is just what I use.
A battery minder Grouser pointed out should have these two features. The first being a trickle charge type charger (gives the battery a very slow charge which is the best charge for a battery) The second feature is make sure the charger has newer technology that will shut off any charging once the battery is completely charged. If the charger you use does not have this feature? Means it will over-charge your battery and render it useless.
One Charger that has been around for a while and meets these charging requirements is called a "Battery Tender". They cost around $30.00 for their cheap model (I would spend a little more to get something that will last you), all you need to do is plug your Battery Tender in, and then go check the battery once in a while to make sure the cells are up to the level they are supposed to be. It's that simple! If the charge goes down while the Tender is attached? The charger will automatically turn itself back on, charge the battery, and turn itself off again.
Even if you don't remove the battery from your ATV (when charging acid fumes and a little acid does leak. So if you don't want this on or near your ATV? Remove the battery and put it someplace safe and dry when it is charging) Most chargers come with a small plug-in adaptor that attaches to the battery terminals and hooks back into the charger itself. So you can leave the battery in place, and use the plug-in pigtail to maintain the charge when the ATV isn't in use.
These are a few ways I keep the batteries in my equipment and just about everything else I own in good shape. If we take care of the battery? The battery won't let us down when we need it. Usually :>)
By working on something that is already broken. What is the worst you can do to it by trying to fix it?
