I used this to replace the original external battery (battery 2) on my Lenovo Thinkpad T480. The original interal battery was replaced about 6 months ago, and the external one still said the health was good at the time. However, it recently began a rapid decline and then would no longer hold a charge, at times preventing the laptop from charging the internal battery as a result. This arrived just over 70% charged, which is what they should be, and was immediately recognized and began charging after inserted. So far, so good, the performance is wha should be expected from an extended battery, and coupled with the internal battery I now have approximately 100Wh of battery to work with, more than enough to last all day without access to a charger. For the price, I consider it a great deal.

It works great. The installation was easy and it saved me from an expensive repair cost.

Works ok...does not keep charge for long but its workable

Good battery but something is preventing charging...time to buy a new laptop. Nice they included a small Phillips screwdriver, came in handy.

Works great and easy to install. I was skeptic but holds a good charge. Came with all the tools needed...

Unfortunately, after installing this battery, my son’s gaming laptop became completely unresponsive and would no longer power on, even after reinstalling the original battery. The laptop was taken for diagnostic testing, and the technician found a short circuit in the area of the battery connector and the power/charging circuitry on the motherboard. As a result, the laptop is now considered beyond economical repair. I cannot say with certainty whether the battery itself caused the problem or whether another issue occurred during the replacement process. However, the laptop was functioning normally before the battery replacement, and the failure happened immediately afterward. I was present during the installation and did not observe any obvious mishandling, bending of components, or use of metal tools that would have suggested accidental damage. This has been a very disappointing and costly experience, as the laptop was worth approximately $1,200. I am sharing my experience so that other buyers are aware of what occurred in our case and can make their own informed decision before purchasing. A return was requested, and I received a notice of full refund, which I appreciate. However, that does not bring the laptop back to life. Please be mindful before deciding to replace your laptop battery yourself, even if you have watched tutorials and feel confident with the process. While many replacements are successful, there is always a risk that something may go wrong, whether due to the replacement part itself or another issue that arises during the installation process. In our case, what was intended to be a simple battery replacement ended with the loss of a gaming laptop worth approximately $1,200. I hope sharing this experience helps others make an informed decision before proceeding with a battery replacement.

Works great. Just as described

I decided an old ThinkPad T480 deserved a refresh rather than becoming E-Waste so I installed Linux Mint on it and upgraded the battery and bought a new charger. The battery has 71.04 of the promised 72 watt hours which is great, i was not expecting it to be that good. Seems like battery will last at least 5 hours, maybe 7 or so, i haven't run it down yet I thought the charge port was faulty but luckily a new charger was exactly what i needed (USB C type)

Ware passt

Todo okey excelente vendedor

está a servir para o efeito

Fast delivery. Battery is brand new, zero charging cycles. Around 74Wh advertised instead of 72Wh. Lighter than expected. Very happy with the product; well worth the money. The laptop turns from an outlet or power bank-dependent device into an actually portable one. I will update my comment when the battery reaches end of life, to see how many cycles it lasted.

Prima Akku, passt hervorragend. Sauber verarbeitet. Immer wieder gerne......
