Why Vax ONEPWR Battery Not Charging?-【Causes & Fixes】

I’m using a Vax ONEPWR Blade 4 cordless vacuum that gives approx 80 minutes of run time on a single charge.

But yesterday, I noticed that my VAX ONEPWR battery flashes red and won’t turn on.

I reached out to the Vax customer support team for help and suggested a few solutions that fixed the charging issue of my Vax ONEPWR battery.

The battery would have completely drained if you ignored the red led flashing when vacuuming the floor.

And it will not charge until you plug it in for at least 3 hours. So, plugin your Vax ONEPWR into the charger and leave it for at least 3 hours.

When you unscrew the battery pack, you’ll find a series of five 3.7V 1800mAh.

    • If there is a build-up of debris around the brush roll preventing it from turning, then the power will automatically stop and the charge light will flash red. You should remove the brush roll and clean it.

  1. The red light is flashing when I have my battery on charge as it keep cutting out when I tried to clean floor. Roller brushes are clean??

    This is virtually brand new cleaner…

    Please can you fix this yet again

      • Got the same problem had it with 3 batteries now, led 1 and 3 flashing believe it’s to do with running battery down to low, have had 2 replacement batteries very frustrating, that is conclusion any way but no idea how to fix it. Just rang Vax and they have replaced them free of charge on warranty
