HP Battery Checker

The HP Battery Tester is a user-friendly function that is available on HP laptops that delivers info on the status of the batteries installed in the notebook PC. It reports on the state of both the primary and secondary battery if the specific notebook is furnished with a secondary battery.
On the Battery test  display panel, the info is prearranged into three indicator areas - Installed Batteries, Health, and Storage Ability. These displays update every five seconds. Messages showed on the panel offer valuable information about the battery status, and any activities that need to be taken.
