9 Cell 57++ New Battery Replacement for Lenovo ThinkPad T440P T540P W540 W541 L440 L540 45N1152 45N1153 0C52864 11.1V 8960mAH1

My 6 year old Lenovo W540 needed a new battery last year, so I did some research and ended up purchasing the 57++ from Amanda. It seemed like a good value. Life was good. But trouble ensued. After 8 months, the battery just up and died. Suddenly, it would not charge. I contacted the seller via Amazon and, much to my surprise, I had a response in less than 2 hours. Wow, pretty amazing! I'll spare you the boring details. I received a warranty replacement yesterday (4 days earlier than expected), immediately installed it and charged it. Then I worked on my laptop last night for over 3 hours. When it was time to quit, the machine said I still had over 4 hours remaining battery life. How'd they do that? So, great new battery and very excellent customer service. I would definitely buy from this seller again! Thank you, Amanda!

I purchased this replacement battery for my ThinkPad which I use for school and work. After about 10 months of very consistent use, the battery started getting really hot and running out of life quickly. I contacted Amanda as the warranty is for 12 months and she responded within a day! After providing my details, a brand new battery arrived in 2-3 days and a return label for the old, faulty battery. I'm super stoked this experience was so smooth as my laptop is very essential right now. Would definitely buy from Amanda again, I appreciate the professionalism and politeness!

I’ve had it for about 100 days. Worked decent, but battery life was a bit shorter than I expected. Used in a laptop for diagnosis where the laptop would generally only run for 10-20 minutes at a time and then be shut off. I had it fully charged, used it for about 10 minutes then shut it off and put it back in the laptop bag. Grabbed it out of the bag about 20 minutes later and realized the entire bag was hot to the touch. Laptop wouldn’t power on. Grabbed my old battery and luckily the laptop still works but this one won’t take a charge now, and I’m just outside of the 90 day return window.

I had the choice of picking this battery for about half the cost I paid from other vendors. I decided pony up a little extra on Amanda because their reviews were much better than the rest. Unfortunately the first battery I received I fully charged and when I disconnected my power it lasted only 3 minutes at 100%. Knowing this could be a fluke I contacted amazon and had them send me a a replacement which came right away. The second battery I am completely satisfied with and has lasted between 5-6 hours each turn. I didnt rate it 5 for the inconvenience of doing it twice, but all in all a good produt and good customer service.

I was a little trepidatious about purchasing a non OEM replacement battery, but I plugged it in when it arrived, and it worked right away in my ThinkPad L440. I haven't fully tested the time it will last, but after the initial charge, I've been using it for over an hour, and my estimated time left is 5 hours. My guess is that I'll get around 4-5 total, which is way better than the 1 hour I could get out of my old battery.

I replaced a 6-cell with this 9-cell, and it's more than doubled the battery life (the old 6-cell had degraded significantly). As expected, it's also more bulky (less sheer) and heavier, but that's the price for more life! I think it's an excellent value for the money!Also, I use a Lenovo ThinkPad Ultra Dock, and this battery works with the dock (of course it does, but I was relieved to find out it did).

just works

I had bought this battery almost a year ago to replace my standard battery that came with the laptop. The battery has consistently only lasted 3-4 hours performing light tasks or browsing vs. The old battery getting 2-3 hours with similar workload. Overall I am kind of disappointed as I expected to perform a bit better. I wound up hanging on to my old battery as back up because I found myself with a low battery quite a few times while doing work.
