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.

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

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.

Battery replacement works great perfect fit.

Works great

This NinjaBatt Pro Battery shipped quickly even without Amazon Prime, and was ready to go right out of the box. It was as easy to install as it was for me to take out my old battery. One thing to note is that while my laptop originally had *2900mAh/44Wh*, this replacement battery has *2600mAh/38Wh*, and I can already tell that while it lasts long enough between charges, it doesn't last quite as long as my original. But I simply could not find a better battery online, making this the best one out there. Even though it's a bit pricier, you really do get what you pay for when it comes to portable laptop batteries. I'm confident that as long as I take care of it (don't overheat and make sure computer settings don't let it drain to 0%), I'll get another several years out of this one (1000 charges....not sure how to estimate that in terms of time).

Works great
