AC14B8K Battery for Acer Chromebook C810 C910 CB5-571 CB3-531 Aspire A515-41G A515-55 A515-55G A615-51 A615-51G A715-71G A715-72G A717-38F 717-72G Nitro AN515-51 AN515-52 AN515-53 NP515-51

This battery brought my old Acer laptop back to life and in full working order! This battery was a perfect fit with no problems at all. I hope that it lasts at least a couple of years.

I bought this battery to replace one that did not fit because of a short wiring harness. This battery fit properly and charged right up.

Installed this battery on a Acer Aspire-5 and so far have not had any problems. It is important to note that the battery should be "reset/calibrated" as soon as you install it in the computer so it can show the true level of charging. My fifth star could come after 6-12 months of use so I can gauge the durability and the charge/recharge cycling.UPDATE: MARCH 2023.** The battery lasted merely 1 year after installing it in my ACER 5 Aspire. It was not holding the charge and when I checked on it, the cells were bloated, something very dangerous because it can explode, as the battery is inside the laptop and it is impossible to know if the battery is in bad shape.This particular battery had been replaced after the one I ordered did not function properly.Unreliable product, cannot recommend it.

Received quickly and fit like a glove! Not always the case. Couldn't ask for more!

I use this battery on my 2022 Acer Nitro 5 gaming laptop, this battery is long lasting up to 4 hour unplug, when I game its a different story, unplug it last about 1 1/2, and this is all have to do with settings on your gaming laptop, if your like me with full setting and massive RPG , playing WOW, it last about 1 1/2 two if I get lucky. When I play hearthstone it last 3 hours. When plug in my FPS is much higher and faster. General use with not gaming battery will last about 4 hrs

This battery was a replacement for the one that came with my Acer Aspire 5 Laptop, which "died" after 4 years of moderate use. Installment was easy, although with this laptop, I had to unscrew almost a dozen screws from the back to get to the battery.I followed the charging advice that comes with the battery. You must fully charge the new battery, and let it lose its charge completely while using it, without re-plugging the laptop in. Do this for 3 or 4 times before using the laptop while plugged in.New battery seems to be doing better than the previous battery in its charged state (which I felt didn't do such a good job to begin with).

Original description said it was the correct battery for the Aspire E3-111 laptop. It does not fit that laptop because the E3-111 correct battery has a large cutout in the upper left corner. I am sure it is a nice battery for the proper laptop.

Works great!
