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.

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.

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.

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.

Computer responds better with good battery even though it’s plug in.

I’ve not had any issues after replacing. Was easy to install.

Une bonne batterie avec quasiment les mêmes performances que l'originale pour bien moins cher. J'en utilise depuis des années et je n'ai jamais eu à me plaindre de NinjaBatt.

This is a great battery works well 78% right out of the box. Holds it's charge well.

Excellent battery...I only use my notebook rarely and when I found it in a poked away in a drawer I realised I hadn't used it for 18 months! I didn't attempt to see if there was any voltage (wished I had) just put it on mains chargeuntil full. I will spare you the hours of updates that it required. This is a nearly 16 year old Acer, original built for Win 7 and being clogged up was an understatement. Saved precoius, wiped the lot. Split HDD and have Win 7 Ultimate for thge same reason people keep vintage cars. the look of it and the Icons put Win 10 & 11 to shame. Not an Apple fan but they kept their 'look' but still look good. I digress, I don't know the average time a notebook battery shoulkd last, as it would depend on the type of work....but it keeps going for several hours as I hoped that using the battery would maintain it's expected lifespan. So well done Ninja...you in my eyes have made and excellent product with and exterior built quality as good as the original! I would recommend you to anyone and everyone, Princes and paupers and the Crowned Heads of Europe...

Batterie acquise pour remplacer celle d'un pc portable âgé de 14 ans. Compatibilité parfaite avec le PC.

Ik was heel tevreden met de batterij. Helaas is hij na 2 jaar op mijn salontafel ontploft. De hele woonkamer vol zwarte roetkwalm. Gelukkig had ik hem niet op mijn schoot.
