Uninterruptible power supply (UPS) battery usually use 3 to 5 years. Life expectancy depends on many factors, including the times you use (equipment must be in battery-powered model) and other environmental factors. Here are some using principles which could ensure your equipment get the best life expectancy:
1. Ensure the UPS is placed in cool, dry and ventilated place. Ideally, the temperature for placing the UPS should not exceed 24 degrees Celsius. Meanwhile, for ventilation purposes, each side should leave about 1-2 inches of space for air circulation.
2. Every year, only do UPS run time calibration for 1 to 2 times when necessary. Sometimes, you can perform run-time calibration to verify whether your running time is sufficient. However, the frequent implementation of run-time calibration will reduce the battery life expectancy.
3. Do not store batteries for quite long time. The new battery can be stored for 6-12 months. After this period, you should use the battery as soon as possible; otherwise they will largely lose their storage capacity. Storage of used batteries is not recommended.
4. The load mustn’t exceed 80% of the rated capacity of UPS equipment, since this would result in reduced run time. Load increases, the running time will be correspondingly reduced. If the power can not supply, full load running UPS will run out and release its battery electricity soon, which will reduce the battery life expectancy. Note: To ensure longer battery run time, do not connect laser printer to the UPS backup battery socket. And ensure that laser printer uses the “Surge only " outlet (using the appropriate model) . For those without “Surge only” outlet UPS, we suggest connect the laser printer to a separate surge suppressor.
