AGM Lead-Acid Battery

An external universal battery manufactured using AGM technology is a fully sealed external power source that requires no maintenance during storage and operation.

The manufacturing technology for universal external AGM (absorbent glass mat) batteries involves an absorbent fiberglass separator inside the battery. This type of battery performs excellently under increased loads.

A front-terminal battery differs from conventional lead-acid batteries in its form factor. Batteries of this type have a flattened casing and front-mounted terminals, allowing them to be connected to each other and installed in server racks, telecommunication cabinets, and other specialized structures. The dimensions of front-terminal batteries allow them to be installed in 19" or 21" server racks.

Advantages of AGM batteries:

• The charge/discharge cycle life of an AGM battery is 400* (typically 5 years, depending on operating conditions).
• The battery can be installed in residential premises. The absence of free liquid electrolyte between the plates and the fully sealed casing prevent acid leakage and guarantee no harmful fumes.
• These batteries show stable results in practical use when operating in low (-20°C) and high (+50°C) ambient temperatures.
• In operation, an AGM lead-acid battery can withstand prolonged discharge, cyclic discharge, deep discharge, and high-current discharge.
• Batteries of this type have low self-discharge rates during long-term storage and reliable self-protection against over-discharge and over-charge.

Features of AGM Battery Production

Inside an AGM battery, porous insulating separators made of thin fiberglass are placed. The separators and electrode plates are tightly pressed against each other. Thus, there is no free liquid electrolyte between the battery plates, as it is contained within the separator and the active part of the electrodes.

The amount of liquid electrolyte is metered so that small pores are filled with acid, while larger ones ensure gas circulation.

The battery design features an improved gas recombination system – oxygen and hydrogen, formed as a result of chemical processes, do not evaporate outside the sealed casing before condensation.

Areas of Application: Why is an AGM Lead-Acid Battery Needed?

A universal external charging battery is used:

• In telecommunication and other communication systems, including as an external battery for charging mobile phones, two-way radios, etc.
• For equipment in video surveillance systems, security, burglar, fire, and other alarms.
• In uninterruptible power supply systems for server stations.
• As a power source for medical, laboratory, commercial, and other specialized equipment.
• In energy storage systems from alternative sources (batteries for solar panels).
• As a battery for emergency or LED lighting fixtures.
• As batteries for uninterruptible power supply units and UPS.

Which batteries are suitable for emergency lighting systems in Ukraine, and which battery should you buy for a UPS?

The choice of battery depends on the power of the connected consumers, as well as the required autonomous operating time of the electrical equipment from the battery.

An external AGM battery for a UPS must have sufficient capacity, a wide range of operating temperatures, and a long service life.

Before deciding which battery is best to buy for a UPS, carefully study the parameters of the uninterruptible power supply and determine the amount of time required for autonomous operation of the electrical equipment.

AGM batteries are in high demand among consumers who want to buy an inexpensive and universal battery for a heating boiler, emergency lighting systems, or autonomous water supply.

How to avoid battery capacity loss in conditions of frequent power outages?

Two important rules for caring for AGM, GEL, MG batteries:

1. Do not frequently discharge the battery by more than 30% of its capacity (consider this when calculating battery capacity)
2. After discharge, the battery must be fully charged with a current of 1/10 of the capacity for 10 hours

IMPORTANT! If a group of several batteries connected in parallel or in series is used, then:

• all batteries must have the same capacity,
• be of the same type (AGM, GEL, or MG),
• have the same voltage, the same number of charge/discharge cycles,
• be from the same batch of the same brand.

Violation of these requirements leads to premature failure of one or more batteries and is not a warranty case. More detailed information can be found in our article.
