Working well in MSI Stealth m15
Fit great into my 2021 MSI Stealth m15, replacing an OEM battery that would no longer hold a charge. So far it's been working great, holding a charge like it should, and the laptop seems happy with it. Have only been using it for a couple days, but so far so good!

Don't waste you money and time
The battery worked for 8 hours, the decided not to work anymore. Can't return the product beacuse i live outside the USA and the shipping costs are higher than the refund

Dead after 3 months
I bought this battery for my MSI laptop. Worked great for 3 months. Now it says 100% charged but if I unplug it, it turns off immediately. I also tried calibration but it turns off unexpectedly. EDIT: Changed from 1 to 3 stars. Seller offered a full refund no questions asked.

Just what I needed
Product works for my Alienware 15 laptop. I got it installed by Best Buy. By battery life is better than I expected with this battery and it lasts around 5-6 hours. I replaced my original Alienware battery after 3.5 years because it wouldn’t hold even two minutes of charge at that point. I definitely would buy this battery again

Battery dead after putting it inside laptop
After I had put it in my laptop, the battery was recognized by my laptop. Unfortunately it stayed at 44% for hours. After I had unplugged it to see if there was a problem with the charger, it died.

Avoid at all costs!!!
I purchased this battery per my IT repair department’s request to repair my current computer, and although it worked, It was only a week later that the battery crapped out. Look somewhere else for a better battery!!!

this is a 10 wire battery, not an 8 like the image shown
Claims to be 8 wire cable, it's a 10. Unusable
