Due to the charge loss factors listed, it is recommended that 500 series
Intelligent Batteries be recharged about every two weeks to assure that
partially charged batteries do not discharge below the microprocessor
operating level. The PowerCenter will perform the Over Discharge
Recovery operation when necessary but frequent over discharge may
shorten the service life of a battery.
