XPS 1300 fails to charge batteries

[DonDowns]

I recently replaced the batteries with new ones in my XS 1300. The unit showed a nearly full battery level which dwindled over the course of several days when the unit stopped working. I independently recharged the batteries and placed them back into the UPS only to have the same problem of no remaining level. The batteries test at 10VDC when removed. It appears as if the charging circuit is not functioning. Is there a known component malfunction of the internal circuitry that can be fixed?

The hardware is covered by a three warranty as such (IF) in warranty contact APC Technical Support to submit a RMA.

Have ready the serial number, receipt, and brief description of the problem. If there are active faults / error codes relay the same.

If the hardware is (NOT) in warranty you may at your own risk search for APC Charging Repairs on the Internet / YouTube.

In some instances the problem is a failed and out of tolerance capacitor, resistor. In other cases it’s a transistor, relay, etc.

You could be super lucky and find just a blown fuse which you can replace.

For the average person it makes a lot more sense to replace the unit with a new model with the benefits of support, warranty, and extra features.

If you decide to forego the repair you may consider using the APC Trade-UPS program to obtain a modest discount on the next purchase:
