Brought my vL35+ vacuum back to life
My poor vacuum had died in the middle of vacuuming and would not charge. I tried everything from deep cleaning it, cleaning the charging contacts, cleaning the docking station, emptying everything, and manually placing it slowly on the charger. Nothing would make a difference, it would just flash quickly and never take a charge. After installing this battery (which was extremely easy) i was able to turn on my vacuum, it automatically reconnected to wifi, and worked as it did on day one. It holds a charge perfectly and charges without issue

Works as should.
Battery worked. Easy install and replacement. Been a couple of months and haven't had any issues. Not much else to say.

The battery was good, but didn't solve my problem
I am giving the battery a five star review even though I am disappointed with the result. I have an aged Eufy that only produces 95 minutes runtime before needing recharge, I assumed that the battery was getting old and needed to be replaced, but this new battery does not help extend the runtime.

Works as expected
Worked great in my Eufy L35 Hybrid. Powered right up, charges well, no issues with it dying. Exact same setup as the original so pretty easy to install. Glad to have my Eufy working again!

Doesn’t last
Lasted a few months and won’t charge anymore. I really didn’t want to keep replacing the battery seeing that the original had lasted for almost 3 years
