Why do UPS batteries die earlier than expected?
The battery is an essential part of a UPS. The efficiency of a UPS largely depends upon its battery. Regular care and maintenance of batteries keep them in great shape for a longer period.
There are numerous factors behind the failure of UPS batteries earlier than anticipated.
Excess usage
The life expectancy of a battery is quite dependent upon how much it is used. Batteries break quicker when used too much. UPS uses the energy kept in batteries and supplies present to the electrical and electronic gadgets to keep them running during a power cut. The more load or devices you utilize during a power failure, the more power will be sucked out of batteries and they will wear much faster.
Poor quality battery charger
A UPS system has 3 parts: a charger, a battery, and a UPS. The charger is linked to the power supply and it charges the battery when the electrical energy is originating from the energy. A bad quality charger can destroy the battery faster than anything else. Usage of good quality chargers to increase the life of the battery
Overcharging battery
Overcharging causes corrosion of battery plates which ultimately leads to premature battery failure. If your battery is getting too hot, it is an indicator that it is getting overcharged. Overcharging a rechargeable battery causes its early than anticipated failure.
Deep discharging the battery.
Deep discharging is bad for the health of any rechargeable battery. For example, deep-cycle batteries like lead-acid batteries are created to be routinely deeply discharged using most of its capacity. A battery loses its effectiveness and capacity when it goes through deep discharge.
Lack of routine maintenance
Poor maintenance is a major reason behind battery damage. Rust, corrosion, and dryness are the biggest opponents of your UPS battery. Rusting in terminals decreases the current circulation to and from the battery. This restricted circulation of existing results in sluggish battery charging which eventually minimizes battery life. Batteries likewise require regular topping up with distilled water and cleaning. If top-up is not done than battery plates get dried. Dry batteries cannot be saved from failure.
Electrolyte leakage
It is extremely important to inspect UPS batteries regularly for any damage and fault. Sometimes the electrolyte leaks through fractures established in battery. Due to the absence of electrolyte the batteries fail.
