The UPS battery hadn’t been replaced for three years, and it finally exploded today（Part 2)

Like many of me in the past, I’ve fallen into a common misconception about equipment maintenance: simply using it without proper upkeep, focusing only on whether it works on the surface while ignoring the aging and wear of core consumables. A UPS may seem like a backup device, working silently most of the time, but it’s the last line of defense for electrical safety. However, aging batteries can transform from a “safety guardian” into a “time bomb,” potentially triggering a safety accident at any moment.

This sudden battery explosion serves as a reminder to everyone who uses UPS equipment. Here are some practical UPS maintenance tips to avoid similar risks:

First, strictly control the battery replacement cycle. Lead-acid UPS batteries are commonly used in home and office settings .

It is recommended to replace the equipment every 2-3 years. Even if the equipment can be used normally for the time being, do not exceed its service life to eliminate the risk of aging from the root.

Second, pay attention to abnormal signals from the device. Significantly reduced battery life, unusual noises upon startup, abnormal indicator lights, and slight overheating of the device are all warning signs of battery failure. If any of these occur, stop the device immediately and check it. Never use the device while it is malfunctioning.

Third, manage the daily maintenance environment properly. The UPS should be placed in a well-ventilated, dry, and shaded location to dissipate heat. Do not pile up clutter to block the heat dissipation vents, and avoid high temperature and humidity environments that accelerate battery aging. When not in use for a long period of time, it is necessary to charge and discharge the battery regularly to prevent sulfation and failure.

Fourth, conduct regular inspections to identify potential hazards. It is recommended to perform a simple check on the equipment status every quarter, and disassemble the machine annually to inspect battery wear and wiring aging, and clean the dust from the machine body in a timely manner to prevent short circuits caused by dust accumulation.

A seemingly minor battery explosion, though accidental, is actually the inevitable result of long-term neglect of maintenance. Electrical equipment never breaks down suddenly; all malfunctions and dangers are the result of accumulated wear and tear and the hidden dangers sown by neglect. Never take chances; the stable operation of equipment is never a given.

Let this serve as a warning. Whether it’s UPS power supplies, home appliances, or office equipment, regular inspections, timely maintenance, and prompt replacement of consumables are the most reliable safety guarantees. Don’t wait until equipment explodes or an accident occurs to regret your past laziness and negligence.
