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 smartphones.  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
   portion of the Management Information Base (MIB) that provides a
   means for monitoring batteries in or attached to managed devices.
   The Battery MIB module defined in Section 4 meets the requirements
   for monitoring the status of batteries specified in RFC 6988
   [RFC6988].

   The Battery MIB module provides for monitoring the battery status.
   According to the framework for energy management [RFC7326], it is an
   Energy Managed Object; thus, MIB modules such as the Power and Energy
   Monitoring MIB [RFC7460] could, in principle, be implemented for
   batteries.  The Battery MIB extends the more generic aspects of
   energy management by adding battery-specific information.  Amongst
   other things, the Battery MIB enables the monitoring of:
