Uninterruptible Power Supplies (UPS) are essential for protecting critical systems from power failures. However, improper battery maintenance during storage can lead to serious issues, including battery failure, foul odors, and even UPS replacement. Here’s how to properly maintain your UPS battery to ensure reliability and longevity.
How to Charge the Unit
If the UPS is stored without power for an extended period, it’s crucial to turn it on and charge the battery at least once every six months. Battery failure due to long-term storage without replenishment is not covered under warranty.
Failure to charge the battery periodically can lead to severe consequences after UPS operation, such as:
-
Foul odors due to battery degradation
-
Deformation and expansion of the battery pack
-
Leakage, which can damage the UPS and surrounding equipment
2. Prevent UPS Replacement Due to Stuck Batteries
In extreme cases, neglected batteries may become deformed and impossible to remove from the UPS, making the entire unit unusable. If this happens, you may need to replace the entire UPS, not just the battery.
3. Follow Manufacturer Recommendations
The below guide is based on the E11B series replenishment method, following instructions from the E11B series manual, Using the UPS: Basics, section 4. Since replenishment procedures may vary by UPS model, always refer to your specific UPS instruction manual before performing maintenance. Manuals can be downloaded from our website.
To keep your UPS in top condition:
-
Store it in a cool, dry place when not in use
-
Charge the battery at least every six months
-
Regularly inspect for signs of swelling, leakage, or corrosion
Proper maintenance ensures that your UPS remains reliable when you need it most. Don’t let neglect lead to costly replacements—keep your batteries charged and in good condition!
