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!

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.

looking for a battery for my laptop. got this one and seems to work fine.

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

It took me a while to figure out the installation, but it is a good fit for the right model.

Works great
