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

Replaced the OE battery on my Lenovo T-4040 Laptop, this battery is the higher Amp-Hour pack. I can run my laptop for over 4 hours on a full charge with the screen on, Low keyboard lighting and disk drive running constantly...A good quality replacement. It fits perfectly and is the same color as my machine

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 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.

Triple update: it died again ☹️ I gave to wonder if it is worth just buying a Lenovo for the longevity.Double update: I couldn’t help myself and decided to write the seller and within hours they made it right and said they have a 12 month warranty and the new battery was sent and arrived immediately. Wow amanda1! Well done.Update: Negative 5 stars as it has completey died. Total ripoff. Should be banned from selling this product.Battery drains in 2 hours, does not fully charge - shows maybe 2/3 full charge which should at least give 5-6 hours.I got what I paid for - I guess.IMO the reduced price and savings do not justify the reduced capacity. The Company should explain this so a consumer can make an educated choice. Terrible.

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 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).

It only worked for me for the frist two weeks. after two weeks. It won't power on my laptop.After this battery is fully charged, and if I power of my laptop, and unplug power charger, I can't power on my laptop.Edited:Their support team reached out to me! They are very nice! They will provide me a replacement. I will find out if it's just my battery, or overall is not good. thanks

Worked well about a year as described, after that, no longer holds charge and after I unplug, computer dies -- these products should come with a 2 year warranty in my opinion.
