3 Terms, Definitions, Symbols and Classification
3.1 Terms and definitions
For the purposes of this Document, the terms and definitions given in GB/T 2900.41 and the
following apply.
3.1.1 Vented battery/flooded battery
A battery with one or more exhaust devices on the battery cover that can release gaseous
products.
NOTE: Including normal water loss batteries, low water loss batteries and low water loss batteries.
3.1.2 Valve regulated battery/gas recombination battery
The battery is sealed under normal conditions, but has a device to allow gas to escape when the
internal pressure exceeds a predetermined value.
NOTE: This kind of battery cannot normally add water or electrolyte. In this type of battery, the
electrolyte is stagnant.
3.1.3 Maintenance-free battery
A low-water loss battery that does not require maintenance during its service life, provided that
specified conditions are met.
