Ordered for an old Acer laptop and fit and function is good. 5 stars for the value. After going through the battery prep sequences it'll probably do around 4 hours and the price is right for that.

so far it's working just fine. i may have to edit this review or may not have to edit it. I'm hoping i won't.

I bought this for my Acer 5560 computer. This battery was a perfect fit and easily dropped into the battery compartment. I charged it overnight and it got rid of the faulty battery indicator on my computer. So far I have been getting several hours of run time before the computer tells me to plug it in. I think it was well worth the money and would recommend it if you need to replace an old battery.

So far this seems to be a good battery for my old acer aspire 5750. It's the second one I had to buy because the first one from another seller didn't work after I left it sitting for a month. I may need to find one for my msi ge76 raider.

Purchased because my laptop battery wouldn’t hold a change. Ordered and received next day. Popped out the old popped in the new and works like a dream! Easy installation, great price and battery has a charge.

Have had this a few months so can't comment on any longevity. However, as a Computer Scientist I can comment on my observations thus far. 1) No subjective difference from a more expensive replacement of the name brand battery. 2) Battery health, amps, charging rate and so on I've tested multiple times via software and with a meter. All check out 5/5 and thus show no signs of the battery being anything but what is advertised. I'd recommend this battery to anyone looking to replace a battery for matching models. It fit almost as well as the factory. Not difficult to put in, but if you pay attention and have installed countless batteries over the years you will recognize a bit of a difference in design that make it a little less 'smooth' going in. This is by design though. This battery is designed to fit a LOT of different computers. Therefore it won't be designed to every exact nook and cranny of your particular computer and thus the fitment might feel slightly different. However, it goes in very easily (a few seconds at most) and stays in firmly. Not much more you can ask for with a laptop battery imho. Long and short of it: Recommended purchase and I'm fairly particular with these things.
