EXCELLENT BATTERY FOR ME. Everyone is complaining about the battery for the ONEPWR vacuum line. I have a ONEPWR hand vacuum. For me, both the vacuum and the battery. have lasted 9 years of daily use so far. So I don't know what people are doing that is causing batteries to die . Perhaps if it's a full size vacuum that they're using, then that's a different story. Perhaps Hoover should explore different or larger batteries for larger vacuums. Or the user on is leaving the battery on the charger and not taking it off once it's full which is what I do.
So all I can say it's been a great hand vacuum and a great battery. No idea if Hoover changed battery manufacturer or if it's the same manufacturer perhaps that quality has taken a nose dive.
If I was Hoober I would investigate because they are clearly losing business. Hoover has long had an excellent reputation but reputations can be lost out of carelessness. HOOVER: fix the problem! Do a quality check of your manufacturers! Provide tips in instructions on how to prolong battery life: Do's and Do Not's!. Fran. Ottawa, Canada. Tue Jan 13 2026
