Just received this battery. Charges well and works great!

The battery was easy to install, and the price is very reasonable. My laptop is 10 years old and the battery did wonders.

If fit my lab top and working great

Worked fine until I attempted to charge it. It would not allow my Dell to charge it. It disabled the charging capabilities on my laptop.

Just what I was looking for as a replacement battery for my Dell laptop. Fit perfect and was easy to install. Shipping was a day earlier than anticipated so that was good. I can’t comment yet on how long the battery will last as I haven’t had to take the laptop any place yet where I would have to disconnect it from electricity. So far it seems to work fine when I unplugged the laptop temporarily.

for a good value I'm very pleased with its sustainability.

Seems to be working well. I won’t know the battery life as long as it is working. We don’t leave it unplugged very long.

Don't waste your money, this battery is no good.

Fast shipping and item just as advertised , I don’t have any tools to check the usage, plug-in and could be replaced the old one is good enough to me.

I purchase battery on end of october 2022 and on February 2023 battery is useless and can't hold 5 seconds. So disappointed and would not recommend to anyone. I was expecting 2 hours or even hour of run time trough whole year but this is just not acceptable.

Just like factory, very easy to install and worth the money

The battery in our Dell Inspiron 15" laptop finally died and since the laptop is still used (as it's in good shape), this replacement battery does the job nicely. Fully charged, it gives a bit over 4 1/2 hours (not as long as the newer ones but it does the job for us).

Ordered and it was here the next day. Replaced the old one and I can use my laptop anywhere now. Thanks
