BatteryBot monitors and shows your battery charge level (percent) as an icon in your status bar, with temperature, health, voltage, and time since plugged / unplugged in the notification area. It now also has a 1x1 app widget. The Pro version also has user-configurable alarms, logs, mA current information, and a large (4x1) widget.
Give it a try -- it's an excellent and complete solution to your battery needs.
• No ads (why would you want a battery app with ads?)
• Exact battery level in the task bar
• Multiple icon set options
• Automatic time-remaining estimates based on recent usage
• Small (1x1) circle widget
• Notification (with status bar icon) is now optional -- can be used as just a desktop widget
• Very lightweight (please email me if you think otherwise, and I'll help you figure out what's wrong — I promise this app will not drain your battery!)
• Shows 1% increments even on most Motorola devices
• Well-tested and supported on all major versions of Android (2.1, 2.2, 2.3, 3.0, 3.1, 4.0, 4.1, 4.2; Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich / ICS, Jelly Bean) and form factors (small phones, medium phones, large phones, 7-inch tablets, 10-inch tablets).
• Open source
For those who want more than is offered in the free version, or for those who just like to support small, independent developers like me, the Pro version remains lightweight while packing in many useful features:
• Alarms (fully charged, charge above X, charge below X, temperature above X, or health failure)
• (On devices that allow it) Icon colors (including fully configurable green, amber, red, and black icons)
• (On most devices) Electric current (mA / milliamp /milliampere) reading to/from battery on supported devices
• Large (4x1) app widgets
• Battery logging. You can log the battery state (charge, status, voltage, temperature) and browse the logs on the phone or export to CSV.
• Manually or automatically disable / reenable device lock screen / lockscreen / keyguard
• Control the notification priority on Android 4.1+ (For example, you can set to "minimum" to hide the icon but keep the notification in the tray.)
• Lots of configurability of behavior and appearance.
• The charging indicator (the bolt under the number that indicates when the device is being charged) for the sets that have it is optional in the Pro version.
A one-time purchase now gets you free updates for life on all your Android devices.

Here's the BatteryBot business model / philosophy:
1) Ads are annoying. For some apps, ads might make sense, but a system utility should not have ads.
2) The free version should be simple but useful; it shouldn't feel crippled.
3) Some people choose to purchase the Pro version because they want extra features, some because they want more customization, and many because they just want to say "thanks" for the free version and support small, independent developers like myself.
