BatteryBar is a Windows battery meter that monitors battery status and displays it in the taskbar. It retains historical battery data to estimate the time remaining on a battery. Its status popup can show percentage, capacity, charge or discharge rate, power state, estimated full lifetime, AC connection, and battery wear. The maker calculates wear by comparing full capacity with designed capacity. Some batteries do not report charge or discharge rate, or report only one of those rates, so those readings may not be available. BatteryBar has a free version and a Pro version. Pro can show a popup and play a sound when the battery is low, with another notification at critical level, and offers 20 settings for customization. The listed supported systems are Windows XP, Vista, and 7 in 32-bit and 64-bit editions, with a system battery required. Windows XP also requires .NET Framework 2.0. BatteryBar Pro costs 4.00 USD per once for a lifetime license covering one computer; bulk discounts are listed for 10 or more licenses.
