BEST BATTERY COMPANY EVER!!! I ordered a replacement battery for my Lenovo X1 carbon from AC Doctor Inc, it died in 6 months. I contacted AC Doctor INC, doubtful they would do anything. But THEY REPLACED MY 6 MONTH OLD BATTERY WITH A NEW ONE! These guys get 5 stars in my book! I would give them 10 stars if I could. They stand behind their products obviously! Thank you AC Doctor Inc, for being a great company!!

The battery works great. It looks and fits like the OEM Dell battery - easy to install. It was packaged well and came charged at 90%. A screwdriver is included along with an extra screw. The battery health and wear seems to be reporting properly in HWiNFO. Great value for my money.

It’s all good

I purchased this battery in 2020 and it worked pretty well for a little over two years. Once it started to fail, it was very quick. I just bought another replacement. Two years is definitely on the low end of the average lifespan for a battery, but for what I paid, I can't complain.

Installed and worked on a Lenovo X1 Carbon Gen 7. The tools supplied were a nice plus. So far, I've only 24 hours of testing on the battery, including a full battery reset test using Lenovo's Commercial Vantage software. It correctly identified the battery, and had no issues. While it's only been one day of testing so far, I'm hoping this battery will provide reasonable longevity. Adding that after roughly 30 days of use, there have been no issues. I've leveraged using Lenovo Commercial Vantage software to lock charging to 50% of battery capacity, which dramatically increases battery longevity on any Li Ion battery.

Didn't hold charge long-term, and now doesn't work at all. Would power my X1 Carbon Gen 8 for a few hours right after fully charging, but if left unplugged and off, it would drain quickly over a few days. This is for my spare notebook so it mostly sits in a drawer powered off (not sleep mode) and the battery will be completely dead when I go to power the notebook up a couple weeks later (again, it's powered off, not sleep) Now 6-months after purchase it doesn't charge at all. Junk.

Work as described would purchase the item if needed again. Note however, this is based on short term use and not long-term experience.

Battery is an exact fit and has the same specifications as the original laptop’s battery. The included tools helped with the installation which is an easy task. Battery happened to be on sale at the time I was searching for a replacement. So far, the new battery has been performing very well. It’s nice not being tied down to the power adapter plugged into a wall outlet.

I got this battery for a laptop I was given for free with a dead battery, therefore I am unable to compare this battery with the original one in terms of battery life. What I can say is this one lasts about 1h15mins when fully charged. The new unit fits nicely in the slot. I did what another review said and "conditioned" the battery when I first got it to maximize the chances of it performing well. I will come back to edit this review in a couple months if something major happens.

Fits properly and works well

Discharged to five percent, charged, then repeated. Battery life is OK but not great - maybe 1.5 to 2 hours.

Semble bien fonctionner. Dans la journée que je l’ai reçue, je peux dire que cette pile dure environ 2 heures d’autonomie avant d’atteindre 20%. En espérant que ces performances soient constantes dans les prochains mois.

With an older laptop, I was tentative about buying a new battery but the low cost pushed me to do it. The battery Fits my Dell Inspiron, charged quickly, and worked great. After an overnight charge, I disconnected the power, and my Dell kept charge for some 4 hours + . That's great value, giving my Dell a battery backup for the first time in years.
