NinjaBatt Battery for Asus X551 X551M A31N1319 X551C A41N1308 X551MA D550 X551CA A31LJ91 X451 X451C 00B110-00250600 0B110-00250100 - High Performance [4 Cells/2200mAh/32wh]

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.

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.

Works perfectly, no issues

definitely easy to install. charge lasts decent amount, although I was working with a dead battery, so anything seems great right now. i've only bad the battery for a week, so I can't speak to its actual longevity, but overall i'm very pleased with the replacement and i'm happy my laptop is portable again.

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!

Larger AMP hours than original and it is bulkier. Laptop does not sit FLAT any longer while using. it does charge well and lasts up to 6 hours from my basic use

The perfect replacement for my dead computer battery. Compatible with the old battery. Brand new in sealed bag. Was very easy to replace. Just follow instructions that came with battery. Went with this because of reviews and OEM was too expensive. So far, no issues with charging and holding charge.

This fit my Asus laptop and works great so far.
