The safety timer period, mode of battery tem-
perature protection, battery voltage protection
range, pulsed trickle charge duty, and LED dis-
play mode are all adjustable or selectable. Dis-
charge-before-charge function is included to get
rid of memory effect of NiCd batteries without the
risk of overdischarging. Test mode is provided for
charger manufactures to dramatically reduce
production test time.
