Installed yesterday, worked perfectly and solved my battery not charging issue. Came already charged at 63%. Easy install as well. Nice it came with screwdriver a wedge separator which helped remove bottom cover easily.

battery worked great no issues had to return since my laptop stopped working and i no longer needed it but it was simple to install and worked great with my laptop should work with other samsung models too overall it’s a good value for the battery life you get

Very compatible with my Samsung laptop, great price

The battery works in my Asus U56E, and provides reasonable battery life given the age of the machine. However, my first battery failed after just two years, still able to hold a charge, but causing alerts with the charging firmware ("blinking power light") and an occasional hard shutdown of the machine, even while plugged in to the charger. I'm not good enough at electrical engineering to try and understand why; maybe the voltage became too low. I tried to find a compatible battery from a different brand, but still could not find any alternative at such an attractive price point. So I bought a second of the same brand, and immediately all the aforementioned problems were fixed. If you buy it expecting to get no more than two years of useful life out of it, it might still be a good deal.

Good battery. Easy to install

Received these on Mar 10 2025. The batteries have completely stopped charging by 15 May 2025. Batteries are absolute crap. Do not buy this battery. I purchased two of them, had to return one due to it not working when I got it. So received the second one about 2 weeks after I initially got it. So in total, had 3 and they were all trash. 1 star is too good for this product.

Fits and functions, initial charge time appropriate

Works well.
