Internet-Draft Battery MIB February 2013
1. Introduction
Today, more and more managed devices contain batteries that supply
them with power when disconnected from electrical power distribution
grids. Common examples are nomadic and mobile devices, such as
notebook computers, netbooks, and smart phones. The status of
batteries in such a device, particularly the charging status is
typically controlled by automatic functions that act locally on the
device and manually by users of the device.
In addition to this, there is a need to monitor battery status of
these devices by network management systems. This document defines a
