AS16A5K AS16A8K 4ICR19/66 Battery for Acer Aspire E15 E5-575 N16Q2 E5-576G

My wife's laptop is still perfectly functional, except that the battery would not hold a charge. I EASILY replaced it with this, and it holds its charge like new. Fit was excellent, compatibility was perfect, and I only paid like $30. Great value!!

Very happy so far with the battery. I used it to replace the unchargeable battery in my Acer Aspire F5-573-55LV. The battery that came with the laptop is labeled "Acer AS16A5K (4ICR19/66)," 14.8 V, 2650mAh. This replacement is "AS16A5K," 14.8V, 2600 mAh. So this is one is rated 50 mAh less than the original. The removal process is not complicated, although there were 21 screws to be removed to access the battery. Most are the same length and thread, but magnetic dishes are helpful to avoid dropping them. Disassembly guides can be found on the internet for the Acer Aspire F5-573 series. The battery fits perfectly. I did the recommended conditioning procedure 4 times (explained in an included booklet) charging to 100% and discharging completely. 1 week after replacement, the battery holds charge on standby for > 8 hours and 2-4 when in use. Excellent value, fast shipping - arrived in 6 days. The company sent a nice follow-up email to see if I were satisfied with the purchase and an offer to help if not.

Purchased for an Acer Aspire E 15. While the battery easily fits inside the battery compartment, it's only about two thirds the size of the original battery (probably because it's intended for a Dell computer, as noted on the label), and only holds a charge in sleep mode for less than six hours. The original battery still holds a charge, in sleep mode, for several hours longer ('Glad I didn't throw the old, original battery away., because it's going right back in the computer.). Having a lot of experience with batteries, I'd have to say these batteries aren't "New". They're most likely just old batteries that have been put through reconditioning. Over-all, this replacement battery is no substitute for the original battery. On the positive side, the seller does respond to customer concerns in a professional manner. So, aside from my initial disappointment, I believe the seller has the customer's interest in mind.

I've had my Aspire F15 (F5-573T) for several years and it took this long for the battery to finally wear down enough to hold a charge for barely an hour. After a lot of searching, I found this battery for so cheap and I was optimistic and suspicious at the same time! The battery works beautifully and I feel like I have my mobile life back with the laptop. The only hitch (and reason I'm not giving 5 stars) is that it doesn't fit EXACTLY in the slot meant for the battery. It's just slightly bigger but the cover does close over it and the screws still hold everything in place.

Perfect fit

The battery works great

Worked like it should. Easy install. Hope I get 10yrs from this on like I did from oem

Battery didn't last a year before it stopped holding a charge. Easy to install. Checked every other solution before settling that it was the battery.
