Hoover ONEPWR 4.0 Ah Max Lithium Ion Battery, Replacement Battery for Hoover ONEPWR Products, 2X Longer Runtime, Charge Status Lights, Long-Lasting Convenience

The batteries I got from the initial purchase of the vacuum got an error for overheating and they both stopped working. It was...annoying and I was angry but I already had the vacuum so I had to buy this extra battery out of pocket. It hasn't crapped yet and it is working fine. However, it is way heavier and makes it harder to use the vacuum in some areas where you would be carrying it by hand for some duration.

Battery works great

Product is fine but DO NOT buy from The Country Butler. They’re expensive, they will claim to not get the correct item when returned and they will keep your money. BAD BUSINESS!!!

I purchased this battery in September 2025 to replace my old one, which had stopped working due to being defective. This battery was working until recently, when it suddenly stopped charging (the first and third lights are blinking). I like the vacuum that we were using that needed this battery, but the quality of the battery is so poor and inconsitent we will likely buy a new brand.

I might rate this item higher if not for the fact that I had to purchase one to replace the original battery that had come with the vacuum that I wanted this battery for. That battery lasted a few years at best. It worked well enough when I was able to use it, but about a year or two of use was all that I got before the battery just wouldn't charge again, leaving me with a useless vacuum cleaner and a need that continued for a vacuum that serviced my needs. This battery is supposed to be a bit heavier duty and longer lasting than that the battery that originally came with the vacuum cleaner. From what I've been able to tell so far this battery definitely lasts considerably longer than the original it replaced. As in I can run the vacuum cleaner much longer and do much more cleaning with it than I could before putting in this battery. I hope to see at least two to three years of regular life out of this battery before I might have to replace it. I would love to and will pick up a second one just so I have a pair that I can swap between while cleaning around the home. That should cover things nicely in my home.

Perfect, Long run time with my stick vacuum on this battery. I tried 2 other times to buy the non-Hoover look-alike batteries and they sucked and both where sent back. Its worth the couple extra dollars to buy name brand quality.....You get what you pay for.....I will be ordering another one for back up since they work so well........Buy one

Great replacement

After reading instructions for this battery placed into the Charger, it came 3/4's charged, took a little over an hour for the charging lights on the Battery and Charger to stop blinking, which, means it's fully charged. The battery has 4 lights that flash, while charging, in my situation only 1 light was flashing, which indicated it was 3/4's charged when it arrived. This may trip some folks up, as on other devices, all the lights would ON when fully charged, but with this battery, it is the 'other way around'. Light go off on the Battery when fully charged, not on... If you store this battery for a long time, it has to be 1/2 charged, then recharged every 6 months, do not fully charge, if you are going to store these batteries, for a long time.
