The customer service is amazing. The battery i ordered the first time began deteriorating after 3 months of use. I had to charge it often and get only few hrs of juice. I contacted dentsing and they recommended few troubleshooting steps which apparently did not help. So they sent me a new one without any cost to me. They apologized for the inconveniences caused and were very communicative of the replacement part shipment.Let's see how the mileage goes on the new one. I gave it a 5 star because of the customer service. I am not sure if it's the fault of battery or my laptop. But my laptop is only 3 years old (lenovo flex3) and i assume it's probably the battery.Update: the replacement battery is completely dead nearing 12 months of use. This product is of low quality.. have to lower the ratingsUpdate2:The customer service is excellent, they immediately responded to my issues and offered me an option to send a new one or a refund. I accepted the refund as i already tried 2 battery packs from them and didn't want to give it another try.I gave 5 stars for good customer service. The product may have been a bad batch or my laptop itself.

It's great price and this item arrived well packaged and in undamaged & in very great condition. I was impressed and happy that battery was fully charged and it worked as expected. I would definitely recommend this seller to everyone to buy similar products from this vendor. and thank you amazon for such a fantastic service always no doubt about it.Thank you all! 🙏

Bought this to replace my OEM battery. This is worse than my buying OEM battery. But it’s a third of what a battery from Lenovo costs. So I guess I have two batteries that last a crappy amount of time, equating to one new battery’s full charge.

Needed a new battery for my school computer, as the original one couldn’t hold a charge for more than 30 mins. This replacement was great. Now I get about 3 hours of use before my battery gets low and significantly more time on standby. Also had no issues installing new battery, just be sure to check your computer model before purchase. Would recommend.

This battery is a perfect fit for my Lenovo Flex 3. The original battery quit charging after two and a half year. I unscrewed the back cover, unscrewed two battery screws, unplug the battery wire harness... plug this new one in and, voila, it works! I would recommend this "Dentsing" battery to any Lenovo Flex 3 owner.The top battery in the photo is the original, and the bottom one is the replacement that I am now reviewing.

With the help of a YouTube video, replacing the battery was super easy. I've never done something like that before. Turns out, the battery was not the problem, but shipping was easy and the part came as expected.

The battery I needed. Installed without a hitch. Fully charged when arrived. Cycled through charging as directed in the instructions. Very happy! 😊

This battery seemed to be fine, it fit into my computer correctly. Unfortunately, the issue with my computer was not as simple as my battery, but it was something else in the hardware, so I did not end up needing the battery. The return process was wonderful though and I would highly reccomend this seller.
