How to use

Prior to installation, disconnect the UPS from mains power and remove any residual charge according to the UPS manufacturer’s service instructions. Replace the old RBC110 battery by unplugging the battery connector and removing the battery pack; then install the AVACOM AVA-RBC110 in the same position and reconnect the terminals, ensuring firm, correct polarity connections. After installation, reconnect mains power and allow the UPS to charge the new battery following the UPS charging cycle. Dispose of the replaced battery according to local regulations for lead‑acid batteries.

Usage recommendations

For optimal battery life, maintain the UPS and its environment within recommended temperature limits, avoid deep discharges whenever possible, and perform periodic runtime tests. Store unused AVACOM AVA-RBC110 batteries fully charged in a cool, dry place and recharge them before long‑term storage or before installation if capacity has declined.
