4500mAh 21.6V Li-ion Replacement Battery for Dyson V8 Absolute, SV10 Absolute Animal, and Fluffy Cordless Vacuum Cleaners - Compatible with BuTure V8

Holly A. Howard: I haven’t had the battery for long but so far it seems to be working okay. The fit into the charger is more snug and when using the vacuum the trigger to make it run most be held more firmly.

Richard D Harvey: When attached to my charger which is wall mounted, it would feel stuck on removal. I suspect this is an alignment issue. I solved the problem by using dielectric grease on the connector.
The battery life and power is at least equivalent to the original. I cannot remember how long the battery lasted when new. Except for the connector issue, I recommend this battery.

Wizard: In reading reviews for dyson replacement battery it was apparent that many of the reviews are phony reviews. I try to be more careful in anything that involves lithium batteries. Although this battery is much cheaper than buying directly from dyson, it was more then all the other batteries I looked at on Amazon. The battery arrived on time and was easy to install. Battery arrived two thirds charged. I immediately used it and although it’s hard to remember how dyson was brand new it did seem to work better then I ever remember. The next day I used it continuously on high suction and it lasted for about 10 minutes. I believe dyson states that a new v8 will last 7 minutes. Have about a week and tested battery again. It again lasted almost 10 minutes on high. Very satisfied so far.

Lauren Green: I don't like to leave a review until after I've used a product for a few weeks. Anything can happen in a few days. This batter is wonderful. I've used it now over 2 weeks and its going strong. I have 2 rooms with carpet and the rest of my house is tile with some rugs. I vacuum my whole house every day including tile floors because pets leave your floor furry. Put a flash light down and see how much covers a tile floor. Thats how I get all the fur up is putting down a flashlight to see all the hair. I don't even loose one batter light. It's still going strong even after using it on strong for the carpets. Very nice and better than the original Dyson battery I got with the vacuum. Very pleased.

Toni Hawkins: I bought this to replace the one the manufacturer. Easy to install looks exactly the same. When I used the hoover for the first time on max speed setting I was disappointed as it didn’t sound or feel like the old battery. BUT as it’s charged and used it’s just as good as the original so much so I’m adding this review to reassure that this replacement battery is a good price and gives your very expensive hoover a new lease of life. But it seems to get stronger after a few uses ... maybe that’s common knowledge with these types of batteries ? I’ve been pleasantly surprised it’s increased in strength and life from the first / second uses.
