Attention: This listing is for a mail-in Repair Service, not a pre-built product. Turn around time is typically 3 days upon receipt. Repaired batteries will be mailed back to you at no additional cost. There are three variations of the repair service: BMS replacement, Cell replacement, or both. The details of each are bulleted below.
BMS Replacement
- If the battery will not power on the vacuum, will not take a charge, and flashes the lowest battery level LED very briefly when pressed, then the battery protection board has failed. This is a common failure for these battery models. I will replace the battery protection board with a more robust model. The battery cells will not be replaced, so whatever run-time you were getting before the battery failed will remain the same after the repair. If I find during testing that your OEM battery cells give a runtime of less than 30 minutes I will contact you and recomend their replacement.
Battery Cell Replacement
- If your battery works, but only for a short while (ie. 30 minutes or less) then your cells have failed. I will replace all (40) battery cells and your runtime will return to 75 minutes like it was when new.
Battery Cell + BMS Replacement
- If you need both the BMS and battery cells replaced, or prefer to replace both as a preventative measure, it’s much cheaper to get both done at the same time.
You can wait to pay until after your battery is repaired if you would like me to diagnose it first. Please fill out a Repair Form and mail your battery to:
