Needed a new battery as the old one discharged in minutes. This one is good. Of course, how long the charge lasts depends on what you are doing with the laptop.

I've bought this product second time already. The battery operates well for 2 years. This deal works for me, $30 for 2 years -- fair price.

The battery in one of our HP laptops started reporting an error and would suddenly lose its charge, so time for a replacement. With a lot of help from videos on the HP website, we were able to replace the battery and it appears to be working well. This may not be a task for some folks, it was a little complicated opening up and removing the battery.

This product worked very well. Easily replaced the old battery. Make sure to do a power cycle (charge it fully then let it run down fully a couple time) once it is in the computer
