gel battery

A GEL battery has some elements, usually silicon compounds, added to the acid to ensure it gelatinises and thereby guarantee that no flooded acid can leak out. The oxygen gas "drills" channels in the gel from the positive to the negative plate where it meets the hydrogen gas and recombines into water. The GEL battery has excellent capacity but the somewhat higher resistance in the acid means that they have limitations as a starter battery. GEL battery can withstand over-discharging very well, i.e. when the GEL battery is drained down to 20% State Of Charge. GEL battery is very robust and is often used in applications such as floor-cleaning machines and golf carts. When a GEL battery are mentioned in a motorcycle context, this is often a misconception. It is more likely to be an AGM battery.
