APC Back-UPS 1000S (BR1000MS) Battery Issue

[Anthony383]

Hello,

I've had this UPS since 2019 and it's no longer in warranty. I've never actually tested that it works but the other day, I unplugged it from the wall, it switched to battery for half a sec and turned off even though the battery meter said 100% on both the LCD and in Powerchute.

I thought the battery was dead so I bought another one, put it in and left it charging for an entire day, same thing. Turns off almost immediately after unplugging. The battery meter continues to show 100% even if I disconnect the battery from the unit. 

What can I do now?

Thanks.

Complete the following action items in this specific order and report back the results:

Brain Dead:

Installation Date: Update the battery installation date via Power Chute.

Self Test: Manually initiate a self test and let it complete. If this step fails call this out with the error message.

Battery Calibration: Once the battery is 100% SOC (State of Charge). Initiate a battery calibration with at least 30% attached load on the outputs. Let this process complete and battery return to 100% SOC.

Wait an hour than remove AC Mains from the wall outlet. What are the results of doing so?!? Report back what Power Chute indicates as the current load (power) and estimated runtime while running on battery only mode.

Done - note that the battery indicator on the LCD and in Powerchute still shows 100% charged even if battery is disconnected.

Installation Date: Update the battery installation date via Power Chute.

No such option in Powerchute or the onscreen menu. Tried to manually calibrate by putting a 30% load and unplugging from wall, i hear a click and it turns off. 

I've tried putting in a known dead battery. Left it overnight for around 10 hours but not sure if it was charging since the charge indicator showed 100% still. Same issue, turns off immediately after unplugging from wall whether there's a load or not.

Tried putting in a fully charged working battery from another UPS, same issue.

The hardware will need to be repaired, retired, or recycled. You may consider using this APC Resource link relating to the trade-ups program:

https://www.apc.com/shop/tradeups/us/en/search

Its a good way to recycle while getting a modest discount on a new UPS system.
