How to discharge a UPS battery
Thread Content
The UPS has been in operation for a year, and it is now time for maintenance. Has the battery pack not been discharged for a long time? How should the discharge operation be carried out? What are the technical requirements? Are there any specialized devices for discharging battery packs?
A crude method: cut off the power supply and discharge it with an appropriate load.
We generally follow the instructions, applying it once a month; this is specified in the relevant equipment maintenance procedures.
When we want to discharge it, we connect the battery to an electric furnace for discharge.
No special equipment is required; just one or two full charge and discharge cycles are enough. Check the status of the UPS before making a decision
Actually, discharging is very simple – just turn off the main circuit. The main thing is that the discharge current must be limited: for example, when using a 100AH battery, the discharge current should not be less than 10A; it is recommended that it not exceed 40A, as otherwise it will have an adverse effect on the battery, though it will not affect the main unit. At the same time, since the condition of the battery is unknown before the discharge test, it is recommended to turn off only the input to the main rectifier circuit during discharge, while keeping the input to the electronic bypass intact. The specific procedures can be followed according to the instructions or operating guidelines
It’s quite fresh, haha. May I ask how it’s done exactly?
This method works! Could you give more specific details?
