AP15O5L Battery for Acer Aspire S 13 S13 S5-371 S5-371-52JR S5-371-56VE S5-371-7278 S5-371-53NX S5-371-71QZ S5-371-5693 S5-371-757T S5-371-52UK S5-371T S5-371T-78TA R13 CB5-312T 11.55V 53.9Wh 4670mAh

The battery has 2 legs on the bottom that were too long and were not in the correct location. (See Pics.) The laptop would not close properly and the mouse pad would not work. I filed the legs off so it could fit and the mousepad could function. Easy peasy. Now, just need to wait and see on how long the battery lasts.Update Feb 18, 2023: Increased from 3 to 5 stars because the seller contacted me after my review. They offered a refund without wanting anything in return. I appreciate a seller that cares about the buyers and does what they can to make things right. The new battery also increased the unplugged time from 30 minutes to over 8 hours. It's great to not have to carry an extra charging wire around anymore.

The battery I received did no work. It would not hold a charge. I recommend picking a different brand if you don't want to waste your time.

Excellent product.

Seemed to be a perfect fit for my SP513-52n.Charged fine and has been working from the battery most of the day.Hopefully this will last a couple of years.I did have one problem after installing it - the mouse seemed to go crazy, but I'm pretty sure something was pinched inside when I put it back together. I took out all the screws and decided not to put in all the screws. It works fine now.

It is not compatible with Acer S5-371 notebook. The battery did not have the screw clips in the bottom where it is attached to the motherboard. It also took way longer than expected to be delivered. Supplier should add more detailed explanations in the description of the product.

Great battery, easy install.

The battery purchased just two months ago does not hold charge (0% level). Purchase fulfilled by Amazon, so no way to get a replacement after 30 days. Amazon customer service provided link to manufacturers? or sellers? site in India while the product clearly states it was made in China.

I can not recommend this battery. After only 2 months it will no longer take a charge. Poor quality product to say the least and there is no product support. I would hope the supplier would consider replacing it at no cost.
