Off-Season Battery Maintenance: Keep Your Batteries Safe Through the Winter

Posted: January 3rd, 2013

Batteries are like living organisms. They periodically need exercising and maintenance to prevent sulphation from building up on the battery plates. Batteries that sit unused for a long period of time (longer than four weeks) need a maintainer.

Think of ice cubes. The water freezes because it sits dormant. Running water never freezes because the molecules are always in motion.

The same is true for your batteries. Maintaining the battery keeps the molecules in motion. When maintained, sulphation won't rear its ugly head (just like the ice in a flowing fountain).

How a Battery Works

Posted: December 26th, 2006

To help illustrate how a battery works, let’s begin by using a more simple battery like the alkaline. All batteries have a cathode (positive) and an anode (negative) portion of the battery.

How batteries work

The alkaline cathode is a mixture of manganese dioxide, graphite and an electrolyte. This mixture is granulated, aged in storage and then compacted into hollow cylinders called preforms. These preforms are inserted into a steel can. The steel can and mixture now become the cathode, or the positive charge of the alkaline. To keep the material from leaking, an indentation and sealant are used.
