Review: I had to replace the two batteries that came with the vacuum - 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.

## Questions & Answers

**Q: Will this battery work as replacement for mod. bh50121 hoover air cordless?**
A: No it will not.  Just look at the picture of the Onepwr battery compared to the BH03120PC battery.  The terminals are flat and the battery is flat on the connection side.  The Onepwr battery terminals are inside of a plastic box extension on the bottom of the battery case.  I don't see how one would work with the other.

**Q: Will the 4ah li battery charge on the original one pwr blade charger (bh05000)?  or is a different charger required?**
A: This battery in question will work on the charger you have. All Hoover ONEPWR batteries will work with a Hoover ONEPWR charger. Thank you!

**Q: Does the 4.0 battery work with the Hoover Exact?**
A: I’ve haven’t heard of the Hoover Exact. The battery worked with my Hoover ONEPWR Vac.

**Q: Will this work with deik model no.: vc-r201al?**
A: No this is a Hoover One Power Battery designed for Hoover products

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!!!
