I purchased the DMKAOLLK CI03XL battery as a replacement for my aging HP ProBook 650 G2, which had been struggling to hold a charge. Installation was quick and easy—just a few screws and it fit perfectly, no forcing or adjustments needed.After a full charge cycle, the battery life is excellent. I’m getting around 4–6 hours of use depending on workload, which is about what the original battery gave me when the laptop was new. It’s made my laptop actually portable again, which is a huge relief since I travel a lot for work.It arrived well-packaged, and the build quality feels solid. No swelling, no weird fit issues, and no overheating—just a straightforward, reliable battery. It’s also recognized by the system right away without any BIOS or driver issues.

Works great and my laptop is running way smoother.

Great battery. 3 full to empty charges so far. With minimal interaction it goes a full 10 to 12 hour day.

Battery was as advertised, easy to install, working well so far.

Hopefully it will last as long as the HP battery... (7 years & THEN JUST TOTALLY DIED & would not take a charge) !

Battery lasted less than a month , Then wouldnt charge .

Stays charged for perhaps longer than the original ever did.

Battery life is limited
