Perfect replacement battery
I contemplated buying a new vacuum. Instead, I am glad I decided to order a replacement battery. It is identical to the original battery, charges quickly, and works well.

Works great!
Bought to replace my failed 2.0Ah battery A little on the heavy side, but the battery lasts for a looooong time The footprint is also a little large, but nothing too crazy Love it, worth the money!

Doesn't hold a charge well.
I bought this as a secondary charger for my Hoover cordless vacuum. It just doesn't hold a charge as long as the one that came with the vacuum.

Nice backup battery
I always buy an extra battery for my cordless vacuums. My Hoover Lynx died after 8 years, but the 2 batteries were still giving me at least 10 min of vacuuming time. My new Hoover Evolve Elite battery gives me about 15-20 min of vacuum time, depending on whether I use it the whole time on high or not. The extra one I bought on Amazon does the same. I like the easy feature that allows you to check how much battery is left. The only downside is that this battery is expensive at $99, but the Hoover site is more. I can't help but compare the price to the Lynx batteries that were half that price. The charger is easy to use and I always have a battery ready to use, if needed.

Battery stops working after 6 months
I have purchased three of these batteries in the past two years. I have purchased two of these vacuums, and the battery constantly becomes unable to hold a charge after only about six months to a year. Itโs a complete rip off. I would not recommend buying the Hoover vacuum that it goes with or a replacement battery because they do not last!! Durability: Is horrible. Only lasts a few months. Charging ability: after a few months, it will not charge again. I have had to replace this battery 3 to 4 times in the last two years. I have contacted Hoover and they sent me one one time and that was it the rest of the time I just had to buy a new one!

good product
When I buy a new battery operated device, I always buy another battery. If you are vacuuming, you don't want to stop and wait for the battery to recharge. If your battery operated flash light dies, you really need it at that time. Always buy an extra battery because 4 or 5 years down the line, the battery will probably not be available for purchase unless you buy from a specialty sight online and it will cost you twice as much!
