I have had this battery for several months and it works great.

Very good laptop battery, it actually works !!! After trying several other sellers Dr. Battery comes to the rescue. Several other battery's caused compatibility issues on my Lenovo Think Pad. Not this one, functioned as it should with good battery life. Good purchase from a Good seller ......

Battery only lasted 10 mos.

Replaced the battery in the wife's laptop. She is happy so, so am I!

Seems to work for my laptop, but it's slow or very weak to recharge

I've purchased other replacement laptop batteries but this one actually was compatible with my Lenovo.

As bad as my failing battery that I replaced with this

The laptop's old battery was so bad I couldn't get the laptop to turn on. The new battery got me past that, but it's not great. I don't think it'll last an hour even with the laptop doing minimal work. But... Good luck finding good replacement batteries for anything old. It is what it is. 🤷‍♂️

I bought this as I had bought a second hand IdeaPad Flex 14" (2014) which had a dead battery where if you took the charger out, it'd immediately die.This battery lasts around 4-5 hours on Linux. You'd probably get better battery life on Windows as it's more optimized. But overall works great.Just make sure you go from 100% to 0% first few charges, and it’ll work well.
