AP18E7M Battery for Acer Nitro 5 AN515-44 Nitro 7 AN715-51 Nitro 5 AN515-54 AN517-51，Predator Helios 300 PH315-52 PH317-53,Aspire 7 A715-74G,AP18E8M 4ICP4/69/90 4ICP4/70/88 KT.00407.009 KT00407009

it came fully charged so I didn't have to wait , just installed and start my old computer!.

I bought due to my original laptop battery being dead. I took it into Batteries Plus, and they installed it. I didn't want to mess anything up. I charged it for 3 hours, let the battery go down to 30% and now keep it plugged in when I don't have to take it where there's not an outlet.

So far very good. The order came quickly, and included two screwdrivers for the sizes needed to install the battery and replace the laptop cover. Installation was quick and the battery life is over 4 hours. I can get a few more years out of a 9 year old Yoga laptop, which is great!

Bought this for my Acer Aspire One 0756. Fits perfectly although as some others have stated it sticks out from the bottom a bit as it is a 'high capacity' battery and the laptop will sit at a bit of an angle with the battery installed instead of 'flat' like the one included with the laptop. The good news is that this battery does work and gives longer life than the one that comes with the laptop from the factory which on mine was rated at 2,500 mWh. Upon doing a battery report under Windows 10, which I have installed on my Aspire One the 'design capacity' is listed as 57,720 mWh but the 'actual' charge capacity is listed as 44,389 mWh. I did two battery run down tests so far from full charge and found that on very light usage with display at about 3/4 brightness I got about 4.5 hours of battery life. The second test I used the laptop a bit more...surfing a number of websites, watching several youtube videos...and the battery life reduced to about 3.5 hours. This is compared to about 2 hours on the battery that shipped with the laptop which has roughly a little less than half the stated mWh battery charge capacity according to the Windows 10 battery test. So while this battery is not going to get you 7 or 8 hours of use I'd still rate it a good value because of the great $18.49 price. I did one more test before I published this review and charged the laptop to full and then reduced the screen brightness down to about 25% and literally did nothing on the laptop. I wanted to see how it would fair if it were being used just to read contents on the screen. The laptop lasted 6.5 hrs this way before automatically shutting down. Not bad for an under $20 battery. But realistically if you're gonna use this battery normally with brightness up 3/4 and typing on it, surfing the web etc...i'd expect to get around 3-3.5 hours from it.

DO NOT BUYI purchased this battery for my 2018 MBP on October 13, 2025 and as of this review (August 10, 2026) it's been less than a year, it is already swelling and my keyboard is bent because of it and screen unable to close properly. Amazon will not do anything about it because it's past the return period and product support from manufacture is non-existent.

So far, this battery works flawlessly as a replacement for my Acer Nitro 5 battery. The battery life is also great and like it was when my laptop was new. I recommend it 100%
