BATTERY INFORMATION
General Battery Terms and Definitions
54 VX 685/VX 690 INSTALLATION GUIDE
Charging
Refers to the process of converting electrical energy, in the form of electric
current, from an external source (charger) into chemical energy within a battery
cell.
Current
The flow of electrons through a conductor, measured in amperes
Cycle
This refers to the number of charge/discharge cycles the battery can endure
before it loses its ability to store useful charge.
Dead Battery
A battery is considered “dead” when it deep discharges to the point that it can no
longer accept a charge or when it has reached the end of its cycle life.
Deep Discharge
The state of a battery that has been discharged well below its useful charge level.
When a battery is in this state, it may be difficult to recharge. This characteristic
indicates a reduced cycle life.
Discharge Time, Run Time
This refers to the amount of time a battery can provide power to a system before it
discharges fully. It is a function of the load that receives power from the battery.
Discharging
Refers to the process of converting the chemical energy of a battery into electrical
energy, and the transfer of the electrical energy into a load.
Self-Discharge Rate
The amount by which the charge of the battery is reduced without providing any
current to an external terminal or load.
NOTE
The terminal’s battery pack retains approximately 70% of its original charge after
300 cycles.
