Rated Capacity - The number of ampere-hours a battery can deliver under specific conditions (e.g., rate of discharge, end voltage, temperature); usually specified by the battery manufacturer.
Internal Resistance (IR) - The opposition exhibited by a circuit element to the flow of direct current (d.c.). In a cell, the internal resistance is the sum of the ionic and electronic resistances of the cell components.
Micro-outage (or micro-interruption) - Total loss in the supply of power for 10 ms.
Service Life - The period of useful life of a battery before a predetermined end-point voltage is reached.
RS485 (Recommended standard RS485) - This standard is similar to RS422A except that the number of possible links is greater and up to 32 senders may be interconnected to as many receivers. This system is particularly designed for local-area networks.
Absorption - The taking up or retention of one material by another by chemical or molecular action.
Current Drain - The current withdrawn from a battery during discharge.
