Why Is It Recommended To Perform A Deep Discharge Of An Uninterruptible Power Supply (ups) Every Three Months?

Deeply discharging 240v ups power supply batteries to 20-30% can reactivate the active materials inside the battery, thus slowing down the process of plate crystallization and increased internal resistance. Performing "small, minor discharges" on online ups power supply batteries is actually detrimental; it is recommended to discharge single phase ups batteries to 20% or lower to maintain the activity of the chemical system.

Regularly deep discharging ups backup power supply batteries and immediately recharging them helps in accurately assessing battery capacity and provides data support for maintenance personnel to determine battery health. While it is recommended to avoid "excessively frequent deep discharges of uninterruptible power supply for home use batteries," periodic operations (such as every three months) can be considered part of a maintenance strategy.
