Let’s Discuss AGM Battery Advantages and Technology

• Deep discharges do not frighten me.

Any battery does not tolerate a strong discharge, and for some modifications, this factor is simply destructive. In the case of standard power supplies, their capacity is critically affected by frequent discharges below 50 percent. AGM batteries can withstand approximately 20% more energy loss without serious harm. That is, repeatedly discharging to 30 percent will not affect the battery’s performance.

• I’m not afraid of steep slopes.

Due to the fact that the battery case is sealed, the electrolyte does not pour out of the container when it is turned over. The absorbed material prevents the working substance from moving freely under the influence of gravity. However, the battery must not be stored or operated upside down. The dump valves will be at the bottom, and the air itself (its formation is possible if the charging process is violated-overcharging or using a device that issues an incorrect voltage rating) will move up. The reason for this is that, in this position, natural removal of excess gas through the valve will not be possible.

• Maintenance free.

If the battery is used in a car, then the process of replenishing the electrolyte volume is not laborious and not harmful. When the lids of the cans are unscrewed, sulfuric acid vapors come out of the container in a small amount. For this reason, servicing classic batteries (including charging them, since at this moment the banks must be open) should be done in a well-ventilated area. If the battery is operated in a residential environment, then such a device must be removed from the premises for maintenance. There are electrical installations that use a bundle of a large number of batteries. In this case, their operation and maintenance in a closed room is dangerous to human health.

Therefore, in such cases, batteries manufactured using AGM technology are used. The electrolyte evaporates in them only if the charging procedure is violated, and they do not need to be serviced throughout their entire working life.

• Not subject to sulfation and corrosion.

Since the electrolyte does not boil or evaporate during operation and proper charging, the plates of the device are in constant contact with the working substance. As a result, the process of destruction does not take place in such power sources. An exception is the same incorrect charging, during which the recombination of the evolved gases and the evaporation of the electrolyte are disturbed.

• Not afraid of vibrations.

Regardless of the position of the battery case, the electrolyte is constantly in contact with the plates since the fiberglass is tightly pressed against their surface. Due to this, neither small vibrations nor shaking provoke a violation of the contact between these elements. For this reason, these batteries can be safely used on vehicles that often drive over rough terrain.

• Stable at high and low ambient temperatures.

There is no free water in the AGM battery device, which could freeze (during the crystallization process, the liquid expands, which is often the reason for the depressurization of the housings) or evaporate during operation. For this reason, the improved type of power supply remains stable in frosts of -70 degrees and heat of +40 degrees Celsius. True, in cold weather, the discharge occurs as quickly as in the case of classic batteries.

• Charge faster and deliver a higher current in a shorter period of time.

The second parameter is very important when cold starting the internal combustion engine. During operation and charging, such devices do not get very hot. For example, when charging a conventional battery, approximately 20% of the energy is converted into heat, whereas in AGM versions, this parameter is within 4%.
