70++ 9 Cell 11.1V 94Wh Battery 0A36303 Compatible with Lenovo ThinkPad T430 T430i T410 T420 T420i T510 T520 T530 L412 L420 L430 L512 L520 L530 W510 W520 W530 0A36302 45N1001 45N1000 45N1010 45N1011

I purchased this battery for my Lenovo T420 as Staples no longer carried a battery for my model. When it finally arrived I followed the break in instructions carefully. It was a perfect fit and is doing a great job. The value for the money was outstanding. The only negative I have is in the shipping. I wasn't able to ship to my P.O. Box and had to use my physical address so I figured it would come by UPS or Fedex. That was not the case as it arrived by U.S.P.S. It arrived 2 days late as it bounced around between two Amazon shipping locations in GA and NC before finally arriving at my P.O. Box anyway. Overall, it was a good experience.

Battery works correctly and charged right up.

good solid battery, restored the run time to my laptop

Works fine in W530 but battery don't snap in securly like original.

After going through a full battery cycle, my laptop is reading the battery as having 98.89 Wh capacity, which is even larger than what is stated in the product description! Also, the cells appear to be Sanyo, which are good quality.

After getting a battery from a non-Amazon computer parts supplier that did not pass the "Genuine Lenovo" battery check, thereby running the computer but unable to recharge ( and returning the battery), I was going to go with a Lenovo branded battery for ~$84, but decided to try this brand based on their marketing photos showing that their batteries were made with the overcharge protection circuits/chips/boards, and should work. On arriving, I installed in my Lenovo W530 laptop, and no error messages, just a normal boot, and recharged from it's arrival level ~57% to 100% in just over 2 hours. I will buy from this manf/supplier again.

To start my t530 has been upgraded to an i7 3720qm and was running a 2core i3 which would last much longer. It is running a SSD as well which is more powerefficient than spinning rust. Runs nearly all day with no power settings set in Arch linux, and max power settings in BIOS. and tons of tabs open/discord and steam open as well. My thinkpad is far from as efficient as the m1 macbook air, but it lasts pretty much all day with this new battery, and i probably wouldn't hesitate to bring it to an office job without a charger. Especially if you're on low power settings in the bios and set the power plan in linux or windows.

The stated capacity of the battery does not match actual. It's not off by THAT much for the price. It was reporting around 80 Wh in Ubuntu. The biggest issue I have with it is the clip/hook that's farthest from the release switch does not work. It seems to be bound up or frozen. Because of this the battery is not very secure in the laptop.
