We present a battery pack that perfectly complements an uninterruptible power supply. This pack includes two multi-gel 12V batteries with a total capacity of 90Ah (45Ah each), connected in parallel to increase capacity and total energy to 1080 watt-hours (Wh).

The external universal battery, manufactured using AGM multi-gel 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 mat inside the battery. Batteries of this type perfectly handle increased loads.

Advantages of a multi-gel AGM battery:

• The charge/discharge cycle life of an AGM (multi-gel) battery is 800* (generally 6-7 years, depending on operating conditions).
• The battery can be installed in residential premises. The absence of free liquid electrolyte between the plates and the complete sealing of the casing exclude acid leakage and guarantee the absence of 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 (multi-gel) 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 multi-gel AGM battery production

Multi-gel batteries are manufactured using advanced AGM technology with thickened plates featuring high anti-corrosion properties.

Porous insulating thin fiberglass mats are placed inside the battery. Separators and electrode plates are tightly pressed against each other. Thus, no free liquid electrolyte remains between the battery plates, as it is contained in the separator and in the active part of the electrodes.

The amount of liquid electrolyte is dosed so that small pores are filled with acid, and large ones ensure gas circulation.

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

Multi-gel 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
