5 Best Stanley Battery Chargers Review 2021

If you have an automotive or marine battery that remains idle for an extended period of time, you will want to keep it in a cool, dry place and well charged with a top-quality Stanley battery charger. The vast majority of automotive and marine batteries use lead /acid chemistry for their operation. These batteries are not cheap to buy, so you want to keep them well charged while not in use. One of the features of these batteries is that when left unattended, they lose their charge at a constant discharge rate. As they discharge, they accumulate lead sulfate on their internal lead plates. This progressively makes them less efficient, and eventually, they could die.

The answer is to hook your idle 12V batteries up to one of several available efficient top quality Stanley battery chargers. These keep your batteries at an optimum charge, so when you take them back to your ATV, RV, or boat in the Spring, they are as good as new!

Final thoughts

Most automotive and marine batteries don’t like being left uncharged for long periods. A Stanley battery charger should be used to maintain the health of your battery when your vehicle or boat is unlikely to be used for weeks or months at a time.

Single, smaller capacity batteries can be kept trickle charged when you don’t need them with either a Stanley BM1S1A or BC209 battery charger.

Bigger capacity batteries such as truck batteries or deep cycle batteries in an RV or boat are best kept charged with a middle range charger like the Stanley BC8S battery charger.

When you need to restore a badly discharged battery, recharge a battery quickly or start an engine when your batteries have failed, then either the Stanley BC25BS or Stanley BC15BS battery charger is the charger you want, both of which have plenty of grunts.
