What BatteryCare is

BatteryCare is free Windows software for monitoring laptop battery use and adjusting power settings. It tracks complete discharge cycles and can notify users when the configured cycle count indicates that a full discharge is due. Battery details include wear level, capacities, consumption, manufacturer, and an estimate of remaining time when the laptop does not provide one. The program also monitors CPU and hard drive temperatures in Celsius or Fahrenheit. A notification area popup shows temperatures, charge status, estimated time remaining, and power plans. BatteryCare can switch power plans based on the computer’s power source and disable Windows Aero or selected demanding services while running on battery. The program updates itself when a new version is available; its maker says it uses 0.1% of processor and memory resources. It is compatible with Windows XP, Vista, 7, 8, and 10. If installation through the installer is not possible, the FAQ recommends the portable version. Microsoft .NET 2.0 may be needed if the program fails to run after installation. Reading CPU temperature requires administrator privileges and depends on hardware compatibility.
