Each  line of batteries has its unique features that account for differences in price and performance. We’ll take a closer look at the two basic types of batteries that  manufactures. These two battery types are: Conventional and Absorbed Glass Mat, or AGM. Conventional batteries have filler caps that allow distilled water to be added to the battery periodically. AGM batteries do not have filler caps and are sometimes referred to as maintenance-free batteries or VRLA (valve regu …

Because AGM batteries are different than Conventional batteries, it is important to keep these points in mind: 1. There are important differences in the activation of an AGM battery versus a Conventional battery. Be sure to follow the instructions for activating AGM batteries. 2. While  AGM batteries dramatically reduce the need for maintenance, they do need periodic charging. It’s important to remember this and use the correct charging method and battery charger. 3. Wh …

One of two chemical processes is always occurring inside a battery at any given time—discharging or charging. Here is how the discharge process works. The electrolyte solution contains charged atomic particles called ions, made up of sulfate and hydrogen. The sulfate ions are negatively charged, while the hydrogen ions have a positive charge. When an electrical load is placed across a battery’s terminals (starter motor, headlight, horn, etc.) the sulfate ions travel to the negative plates …
