UPS Batteries

Use the product finder on the website (www.batterytech.com) to locate your APC UPS system part # and then you will be able to identify the corresponding part # for the replacement battery. The UPS model number is located on a small white label on the back of the UPS or under a removeable faceplate if applicable. The alternative is to locate the part # on the actual battery (inside your UPS system) and use that part # to locate the corresponding replacement part #.

Run-time will vary based on different factors. The individual UPS system being used, the size and specifications of the battery, the power consumption (load) that is being drawn as well as the age of the battery will all have an impact on the run-time.

A sealed lead-acid battery for a UPS system should last between 3 to 5 years before needing to be replaced.

ISSUE: The UPS is not recognizing the new BTI RBC or there is an ERROR message displayed on the UPS after the RBC is installed:

Sometimes the UPS needs to be reset to clear the error message. If you do the following it may clear the error message:

  1. Unplug the UPS from the wall outlet
  2. Remove the battery cartridge (disconnect from the UPS)
  3. Unplug all equipment from the UPS
  4. Wait 30 to 60 seconds
  5. Plug the UPS back into the wall outlet
  6. Reconnect the UPS battery cartridge to the UPS
  7. Connect the equipment into the UPS
  8. Turn on the UPS (it may already be on)
  9. See if the battery will charge (it may take a few hours to get a full charge).

ISSUE: A battery cartridge is still not being recognized by the UPS after trying the reset.

There is a chance that inside the cartridge, one of the cables was disconnected from an internal battery terminal. This can happen during transportation by the carrier if the carton is shaken or vibrates on a warehouse belt during the shipping process. There is an easy fix that takes 5 minutes, but it requires that someone at the customer facility is comfortable with opening the metal or plastic enclosure to locate the potential problem. All that is needed is a screwdriver to open the metal enclosure.

Product: APCRBC124-SLA124 or APCRBC123-SLA123

There is a known issue with the APCRBC124 and APCRBC123 that is easy (and safe) to fix. APC original batteries have the same issue. The contacts (blades) inside the connector of the APCRBC124 or APCRBC123 may not line up exactly with the internal connector of the UPS. If the battery cartridge is pushed into the UPS with a little too much force - it can push the battery contacts out of position, so they do not make a good connection with the UPS. If you can look inside the plastic housing of the battery to see if one or both of the contacts were pushed offline or recessed into the plastic housing, we can then assist with the easy (and safe) solution.

  1. Take a pair of tweezers or slim, needle nose pliers and pull the contacts/blades out until you hear or feel a 'click'
  2. SLOWLY insert the battery back into the UPS so that it makes a proper connection
  3. The UPS will now recognize the battery and start charging it.
