TenHutt 4000mah 22.2V 4.0Ah Replacement Battery

This seller is really good. Great customer service, as my battery went bad during the warranty period. I Got a replacement very timely with no problems.

I needed a new battery for my Dyson DC 44, last year I’d replaced the battery with another brand and it lasted a year. I always run my Dyson on max power and this battery last for 30 to 35 minutes per charge, so I can vacuum my entire main floor w/ 1 charge. The original Dyson battery only lasted 20 minutes on max power per charge, so this battery has 10 minutes additional usage per charge. I hope it lasts longer than a year, at this point I’ve had it a month. I will update in a year to let you know how if it’s still working.

Seemed like a good OEM replacement. Lasted longer on a single charge than original battery. However, after less than 2 years of moderate use, it simply dies a minute after being charged fully. Now I can feel guilty about having to add it to the land fill. While much cheaper than the real deal, ultimately not worth it.

Good OEM replacement for the original battery. The original last around 18months and the last OEM replacement last the same time. So by comparison, it works as well as the original battery.

I'd say it is more than twice the battery life as the original Dyson battery. It also seams to have a bit more power. Defiantly worth purchasing. Color is the same as the vacuum.

Terrible quality. The battery lasted only a few month and was replaced by ten hutt. The replacement has now died after an even shorter perithe dyson lasted for over 5 years - these only for a few months with normal use.

I hope is going to be longer without changing because is 4000mA/h

Installing this battery was a very easy. 2 screws and done. Battery had a good charge on it to start with. In high mode I get almost 10 times as much time as I ever got on the old battery. I can not say enough good things about how happy I am with this purchase. Made my old Dyson like new. (needed a filter also). Thing rocks!
