This was a perfect fit for my Asus laptop! My brother had no issues with installing the battery, it was very compatible. The laptop is running great now and the battery seems to last a good amount of time.

A good quality battery. Remove the old battery first, then install the new battery. Check if the replacement battery is properly installed. Plug in the charger, then power on your laptop and let the charger charge your laptop till 96%. Work with your laptop without the charger until it shuts off on its own. Recharge your laptop now till 100%.and you are good to go.

It is doing the task on my laptop very well

I don't review everything I buy as I'd like to but only when something initially impresses me. This is one of those times. I bought this for my laptop when it suddenly turned off while on battery and even though it would come back on when plugged in, it showed that the battery was on 21% but wasn't charging. I was worried it might be a hardware or software issue with my linux system but started with the obvious that maybe the battery was bad. It was. I bought this and installed it and it worked as normal. A few things stuck out to me I thought I'd mention. First the packaging was very good. I know this shouldn't matter but I love nice clean electronics and seeing it nestled in a nice and well packaged box was good start to me. Second, it came with the screw drivers needed to replace it. Again, doesn't matter to me but my 6 year old son was happy to add these to his new tool collection. And lastly, and above the other reasons, I really loved that it came with a nice "Thank You" card with "Battery Tips". There is a lot of confusion out there with how to take care of batteries like this so thought it was cool that it appeared they were looking out for my best interest and encouraging me to take better care of the battery in the future. Also I noticed it comes with a 12-month warranty where its says "...remember you have a 12-month warranty. Contact us and we'll do anything to solve the issue." Pretty reassuring. I'd give it five stars but want to wait to make sure it's as good as it initially appears.

So far it is a great battery. The computer shows that it has a battery life of approximately 4 hours I guess that will depend on usage. It fits my Asus X522L Laptop, it's an old laptop that I use mostly for media & I don't want to throw it away.

My beloved 10 year old computer started having charging problems in Nov. 2023 (it's a 2013 Asus laptop that I play backgammon on daily). I thought it was a goner - 10 yrs is a good run. So, I bought a backup laptop (it's OK) & ordered a new battery (I like electronics & was in Signal Corps). Looked up changing a battery online also. Took about 10 mins (trying to carefully lift the case apart took the longest) 2 mins to actually change the battery out (pops out - carefully & new one popped right in - carefully). Don't know how long this ninjabatt will last (probably not 10 years), but I will change it out again. And it will be easier now that I know how. Piece of cake & my computer is back to a full charge. Hopefully a great product, at a great price! Thanks - a very happy senior!

Exactly what we needed to extend our laptop RAM and battery. Thanks.

This NinjaBatt battery pack is a high-quality replacement. It provides long-lasting power and has been working flawlessly in my device. The battery pack was easy to install, and I haven't experienced any issues since. I'm very satisfied with its performance and would recommend it to others.

Ottima batteria e ottima durata

Perfect fit, for the price you get a very good battery that as last me 8h straight without charging

Had to change it for a Asus X551AC which was dying. battery arrived on time as promised, was partially recharged and worked out of the box. Price was very competitive as well. I left it on battery for 30 mins without charging it and had no issues. Once plugged in, its charged nicely. Can't speak for longevity as only had it for 2 days so far. Would recommend.

Bonjour, Produit arrivé en 3 jours le 14 Octobre 2020, colisage et colis RAS ! La batterie originale de mon portable (Asus X551C) à rendue l'âme en 7 ans (11Déc 2013) Le fond du portable enfin ouvert, cette petite batterie est facilement mis en place. Faire attention avec les fragiles liaisons clavier/boitier, Cette NinjaBatt fonctionne immédiatement. Ces jours, en usage bureautique, elle tient la charge pendant exactement 3h20 environ et, cela me suffit largement ! D'un bon rapport QP, je m'accorde le droit de recommander cette batterie pour un portable Asus ! Daniel BINTHER
