PLEASE SAVE THESE IMPORTANT SAFETY AND OPERATING INSTRUCTIONS
For correct operation of the equipment, it is important to read and be familiar
with this entire manual before installing and operating the charger.
LOOK FOR THIS SYMBOL TO POINT OUT SAFETY PRECAUTIONS. IT MEANS:
BECOME ALERT—YOUR SAFETY IS INVOLVED. IF YOU DO NOT FOLLOW THESE
SAFETY INSTRUCTIONS, INJURY OR PROPERTY DAMAGE CAN OCCUR.
• Patented electronic timer monitors battery state of charge and automatically turns charger off at full charge.
• Line voltage compensation achieved by flux oscillator ciruit applied to battery charger for high reliability "Minute Man" missile
standby applications. Compensates automatically for AC supply voltage variations. Supply voltage variation + 10% from
nominal = + 1% maximum battery voltage variation, decreasing to + ½% at finish rate with constant electrolyte temperature.
No taps or rate controls to set.
• Automatic taper of charge rate for superior battery life through good equalization of cells and low water use rate.
• Silicon diodes with inherent surge protection operation at a conservative percentage of their rating.
• Convection cooled design for maximum reliability and minimum maintenance.
INTRODUCTION
The Lestronic II battery charger is designed to
recharge deep-cycle, lead acid batteries.
ferroresonant transformer is used to provide a highly
reliable, line compensating unit with a minimum of
moving parts, designed for long, trouble-free service.
A patented electronic timer turns the charger on and
off automatically. This electronic timer determines
full charge of the batteries by measuring the rate at
which the battery voltage increases during charge.
When the voltage stops rising, the battery is fully
charged and the charger turns off.
