01AV427 SB10K97584 61++ Laptop Battery Replacement for Lenovo ThinkPad T470 P51S P52S T480 T570 T580 TP25 A475 A485 Series Notebook 4X50M08812 01AV428 01AV492 SB10K97585 10.8V 72Wh 6600mAh

I bought this battery and its cohort as a pair in late 2023 to replace the 5-yr-old long-life set in a Lenovo ThinkPad P51s. They worked great and still compete with its original batteries for duration (>12h with mostly Web usage).As footnote, I had another experience for a newer-model ThinkPad battery replacement also in late 2023, buying this company's [different] high-capacity battery pack, and got no improvement whatsoever over my 4-yr-used batteries then just under half original run-time. It's important to assess the duration after such purchases quickly, and return bad batteries for replacement, especially if you are able to repeat the battery installation process easily.

Perfect fit.Excellent capacity.

Updated:Seller sent me an updated battery, and this one works great. holds a charge for quite a while. Very happyOriginal review: Laptop says bad battery, won't charge. ReturningNot much more you have to say. Got a "new" battery. Plugged it in, immediate error. Bad battery, won't charge. Restarted. Same error. Shutdown. Left plugged in, came back a few hours later. No new charge.

The battery extended my battery life but it lasted only 4 months before it completely stopped working. It had very few cycles in it and was never damaged physically. I was expecting the battery to last way more than it did.Edit - costumer support was great and sent a replacement really quickly

Do not buy from this provider. Battery is faulty. Will not maintain a charge. Went to return the item and I am two days too late.

This battery fit in my laptop without issue, so it is the exact same size and has the same tabs as the OEM battery. My laptop booted without an issue, and the I ran a battery info script which reported it to be the stated size, and it actually had a capacity of 102% of the design rating. Seems to be holding a charge, I’ve been using it for about 6-8 weeks.

The JIAZIJIA SB10K97584 Laptop Battery Replacement works very well when installed in my Lenovo T480 PC. I had to wiggle it a bit to get it into place, but that worked out. The battery was about half charged when it arrived. It worked with the PC and with my battery charger.It is important to note that this battery is thicker than the original for the PC. However, this gives me an unintended advantage when I am using the PC. The battery forces the back of the PC up because it is thicker. This adds an incline to the keyboard, which makes it easier to use.

Using in my A485 Thinkpad, and after balancing, this works and holds a charge. Would recommend. This is the external battery, and with the internal battery, it runs all day.
