9 Cell 100WH 57++New Battery Replacement for Lenovo ThinkPad T440P | for T540P W540 W541 L440 L540 45N1152 45N1153 0C52863 0C52864-11.1V 8960mAh

Good OEM battery for my Lenovo Thinkpad w451. It fit the slot perfectly & restored my laptops 4-5 hour runtime while unplugged. It performs just like the OEM when the unit, was new. It was super easy to install & comes up to a full charge in about an hour. It is the heavy duty optional battery which should be much more durable.

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’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.

Replaced the OE battery on my Lenovo T-440P Laptop, this battery is the higher Amp-Hour pack. I can run my laptop for around 4 hours on a full charge with the screen on, Low keyboard lighting and disk drive running constantly...A good quality replacement

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).

Fits the the computer, charges fine, but it has the staying power of a emphysemic in a marathon. At full charge, the battery lasts barely 1 hour. For comparison, the OEM battery I have since purchased lasts 4 hours.

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.

Hello, Produit reçu aujourd'hui sans soucis. Fonctionne parfaitement bien sur mon Thinkpad W541. Pas encore testé l'autonomie ni quoi que ce soit d'autre. Je mettrai à jour mon commentaire au fur et à mesure. Update : Premier test, avec le tout premier cycle sans calibrage de la batterie non concluant. S'est déchargé en 2 heures avec une utilisation normale, navigation web seulement, pas d'outils lourds. Je reviens en mise à jour avec le calibrage de la batterie. Update 2 : Affreusement déçu. Ne dépasse pas les 2h30 malgré une utilisation très légère du PC. Merci ANTIEE

This battery had made my laptop portable again. My old battery used to last 30 minutes at most, this battery lasts for up to 4 hours using the web and Lightroom.

Por el momento me ha sorprendido esta batería,ya que la batería en 5,30h de uso intensivo la batería iba por el 50% Acostumbrado a la batería original que no me llegaba a la hora.Tambien he de decir que la batería original del portátil tenía ya 12 años. Actualizaré si veo alguna anomalía en esta batería.

Si adatta perfettamente ma per dare una effettiva valutazione devo attendere qualche mese per osservare la durata della carica che per ora vs benissimo

Ok
