Easily log the percentage of your laptop battery, monitor it over the discharge and recharge period to see if the battery spikes at all - if a battery jumps largely (up or down) it can be the signs of a bad battery. Very handy to have to prove a faulty battery. This program can scan and inspect battery percentage, export them and show graph. Export data to Microsoft Excel, clear and export log, or print graph as record. Installer and uninstaller is included. Very light and simple software to use.
