Sealed maintenance-free batteries can be an excellent alternative to conventional batteries because they do not require constant replenishment.

These batteries are hermetically sealed as they do not require any maintenance on the electrolyte levels. They lose electrolytes at a slower rate because they are equipped with terminals made of lead and calcium. It uses the released oxygen and hydrogen for further reactions, so there is no need to add water. All you need to do is wipe the battery case occasionally to keep it clean.

There are two types of maintenance-free batteries, sealed gel batteries and AGM batteries. Both batteries produce water and oxygen on the positive plate and hydrogen on the negative plate to regulate the water level on their own.

The sealed gel battery is a lead-acid battery, regulated by a valve, which is versatile and durable. It contains electrolytes as well as silica fumes that produce a gel-like substance. The gas recombines internally to make water, so you don't have to constantly check the water level or add distilled water every now and then.

It is highly sensitive to overvoltage while charging and can cause poor performance if the wrong charger is used. Its typical voltage range is 14-14.2 volts, and its float range is 13.1-13.3 volts. These are not as common as absorbent glass mat (AGM) batteries. Since they produce very little smoke, they must be used in places with limited ventilation. They are splash and vibration resistant. In addition, offers the lowest cost per cycle and per month with minimal risk of corrosion and sulfuric acid burns.
