What is a Charge?

A charge is a procedure of charging a battery with electricity. In a battery, charging or discharging is constantly taking place. Sulphate and hydrogen-based charged ions are present in the electrolyte solution. The hydrogen ions are positively charged, whereas the sulphate ions are negatively charged.

The chemical reaction that took place during discharge is reversed when a battery is charged. The sulphate and hydrogen ions effectively trade positions. When a battery is charged, the electrical energy utilized is transformed back into chemical energy and stored inside the battery. The voltage produced by battery chargers, such as alternators and generators, is greater than the voltage at which the battery is open circuited.

The battery may overheat if the charging amperage is higher than the rate of natural absorption, which will cause the electrolyte solution to bubble and produce dangerous hydrogen gas. When oxygen from the air is present, hydrogen gas becomes extremely explosive and is quickly ignited by a spark.

Starter motors, headlights, and other electrical loads across a battery’s terminals cause the sulphuric acid to degrade. The resultant sulphate ions then move to the negative plates where they interact with the active material to release their negative charge through ionisation. This results in the battery discharging or generating electricity.

How is DC current created?

DC current is produced by the extra electron movement from the battery’s negative side through the electrical appliance and back to the positive side. The electrons travel back into the cells and reassociate with the positive plates after returning to the positive battery terminal. When there is no more chemical energy remaining in the battery, the discharge process stops.

The term “natural absorption rate” refers to the amount of charging current that can be applied to a battery without overheating it. Powersports batteries are more sensitive to how much current they can safely absorb because they are smaller than automotive battery types.

Battery chargers shouldn’t use more than 3 amps when charging tiny batteries. Due to their larger current output, the majority of battery chargers used in automobiles are not appropriate. Overcharging a battery will dramatically shorten its life even if keeping it fully charged will ensure its best performance.

It is recommended to not overcharge a battery. Due to an AGM battery’s properties, an excessive boost charge or overcharge will reduce the electrolyte capacity. The electrolyte and starting power will decrease more quickly the longer the overcharge period lasts.

Water cannot be introduced to the sealed battery to make up for the electrolyte that has been lost. Furthermore, overcharging can deform cell plates, which makes subsequent charging challenging or impossible.

Track charging periods carefully to prevent overcharging. If the battery case gets too warm to touch when charging, always halt the charge. Restart charging after allowing it to cool for 6 to 12 hours. The size of the battery and the type of charger will affect how long it takes to charge.
