PDM Equipped With Special Features
1. GENERAL
This document supplements the basic PDM Manual
No. 901356 and provides additional operating, safety
and maintenance information.
Ultra-deep discharging of brand new batteries should be avoided for at least 15 cycles.
These batteries have a superior deep cycle life. However, to dramatically extend battery life, ultra-deep
discharge should be avoided. The shallower the average discharge, the longer the life.
If the batteries are continually undercharged, performance is reduced and life is shortened.
THESE BATTERIES ARE MAINTENANCE-FREE. ANY ATTEMPT TO OPEN THE BAT-
TERY WILL VOID WARRANTY.
