AP18E7M Laptop Battery Compatible with Acer Nitro 5 AN515-54 AN517-51 Nitro 7 AN715-51 Aspire 7 A715-74G Predator Helios 300 PH315-52 PH317-53 Triton 300 PT315-51 Series AP18E8M 15.4V 58.75Wh

I've had this battery for about a month. According to BatteryBar, the battery came with about 48,500 mWh, which is less than the 58.75 Wh that is advertised. 90% of the time I use my laptop during school and to do homework. Overall, the battery lasts me for 3hrs 30min. - 4hrs. I usually get the full 4hrs during school as I'm just taking notes.To give a reference, a few days ago I used my laptop with a full battery continuously to see how long it lasted. I had YouTube playing the whole time in the background, I read PDFs, and browsed online sites. I had no other background program running apart from the internet and my screen was at 20% brightness. My laptop lasted me 3hrs and 30min. during this use. I'm pretty happy with it as my laptop would not last me even 3hrs with its previous battery, and this laptop meets my daily needs.Installing was super easy and I love that the battery comes with four small screwdrivers (1 small star, 1 larger star, 1 flat, 1 X) and one rubber guitar pick. Only thing I'd say I'd like better is that I wish I could've received the battery at full power or at least have it last 4hrs on the use I mainly give it.

My Asus laptop stopped holding a charge, was worried I would have to replace the whole thing, but this hooked up easy peasy lemon squeezy and all is good again.

It works, not long lasting but functional

Original battery in top of pic, replacement (this one on bottom). As you can see it does not look like the product pictured (no Vampir brand/logo on it). For some reason it has a taped over Acer logo where the Vampir logo should be. It has all the same specs and manufacturer info as the original battery so I'm pleased but it's just weird the way tech items don't match up to the photo.Edit: battery only holds a charge for 5 months and laptop goes from 80% to 5% to turning off within 10-15 seconds now so I have to keep it plugged in. Dissapointed.

Well, the battery came in good conditions and it was pretty simple to install, it also came with good instructions and tips on how to use it and install it for the first time.So far, I don't have any issues.I’ll be updating my review once I have used it for over month.

This battery said it was compatible with my Nitro 5 labtop Model AN515-44-R99Q, and sure enough it was a perfect fit. It was super easy to install, and now the labtop is up and working again! 100% would recommend to a nitro 5 labtop owner.

My current battery was about at 50% battery health, and so I decided to order a replacement battery. However, I was really disappointed when I learned that the battery I purchased was ALREADY AT ALMOST 50% BATTERY HEALTH and lasted around the same length as my current battery.The battery itself is functional, but a new battery should be around 90% health, not 50%, and I will be returning this expecting a replacement.EDIT: the company reached out to me and offered me a full refund. However, I had already returned the product via Amazon and Amazon shipped me a new one. The new one appears to be at full battery health, so perhaps the first one was just a defect. Either way, I'm increasing my review to 3 stars given that the situation is resolved

Took 5 minutes to open the laptop and swap out the battery. Fit perfectly and works great would definitely recommend.
