Battery Indicator monitors and shows your battery charge level (percent) as an icon in your status bar, with how much time you have left, temperature, health, voltage, and time since plugged / unplugged in the notification area.
It also has a 1×1 app widget. This version also has user-configurable alarms, logs, mA current information, and a large (4×1) widget.
NOTE: This app will not drain your battery.
