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.

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.

Good product, easy to install, does the job. I get maybe 1 1/2 hours out of a charge. I think with the original battery it would last about two hours. I almost got rid of the laptop because of the original dead battery, but now I'm keeping it around for a while... charge it, but don't leave the charge cord connected all the time. Doing that will drain the battery much quicker.

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!

Direct replacement and works great. Fast shipping.

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

Excelente producto 100% compatible con la marca y la lapto para la cual la compramos.

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

Schnelle und zuverlässige Lieferung. Akku top 👍🏻

La he comprado como batería de sustitución para el portátil Asus, se adapta perfectamente en su posición pues es idéntica a la que trae el ordenador de fabrica, me llevo 5 minutos cambiarla, viene a media carga, la cargue por completo y va perfectamente.
