Works great and was packaged very well and secure! Thanks much for a good product and care with shipping and handling!

Restored an older e-waste laptop back to full function. Battery didn't hold a charge well enough so this battery replacement is awesome. Installation took maybe 10 minutes. Tools were included.

Perfect fit; exact match for the existing battery. Comes with all the tools I needed to open the case. Battery life for my laptop is now back to where it was when the laptop was new.

Bought Vanpir battery that was supposed to be 2060mAh, according to picture. On arrival its a 1950mAh, which is fine but not as advertised. And no Vanpir logo. Specs written in Chinese and not compatible with t480 lenovo laptop.

Works without issues. Cells hold up charge nicely and didn't seem to have battery cycles

Five stars for the seller's speedy reply to my question! I ordered this based on its description as an exact replacement for my old, failing one. Before installing, I checked the part number and specs against the old one and discovered a couple of small differences. Using Amazon's contact link, I asked the seller to confirm this is the correct battery. I was impressed to receive a reply within hours, on a weekend! I installed and cycled the battery as per the instruction sheet, and so far it performs quite well and offers impressively quick charge rate and long life.

Extremely excellent. Was having an issue with only charging to 79 percent initially, but went away with a week I think. I was told by friend this is because battery needs to calibrate to laptop to function optimally. Anyways works perfectly now and fits. Company was actually nice enough to reach out unprompted to ensure I was happy with the battery, which was very nice and I haven't seen that before. Unsure about longevity, got a low price warranty with it though and no issues past month or so. My main point though, is if it charges 79% only, don't be scared, either talk with the nice representatives or wait a week. Would want to buy from this seller again, but I probably won't have to lol

There was a little confusion when I first researched this product. When I entered the model number of my laptop in the search field,, 2 different configurations of batteries showed up. I was faced with a 50/50 chance of choosing the wrong one because I was unable to open the laptop without the tools included with the battery. Fortunately, I ended up choosing the right one! Once the battery arrived, installation went smoothly and the battery is functioning perfectly
