Let's reveal the life cycles or rating of the common HP laptop battery.
It's (ready for this?) ....--------> 300 Cycles.
If you have an owner use the battery daily then in just over a year you'll have an old battery that won't hold a charge. This is sadly common and why I spread the word to use the battery only when necessary and not as a convenience.

Hi all, My 16 month HP laptop has suddenly stopped charging. It was holding charge alright but now it just runs off mains and hibernates when I unplug.
