LESTRONIC II BATTERY CHARGER
FOR MOTIVE POWER BATTERIES
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.
DO NOT DISCARD THIS MANUAL AFTER READING.

IF YOU DO NOT FOLLOW THESE
SAFETY INSTRUCTIONS, INJURY OR PROPERTY DAMAGE CAN OCCUR.
INTRODUCTION
The Lestronic II battery charger is designed to
recharge deep-cycle, lead-acid batteries. A
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.
PROPER CARE OF MOTIVE POWER BATTERIES
Motive power batteries are subjected to severe deep
cycle duty on a daily basis. Although these batteries
are designed to withstand such duty, the following
precautions must be observed to obtain good
performance and maximum cycle life.
CAUTION: ALWAYS WEAR PROTECTIVE
EYE SHIELDS AND CLOTHING WHEN WORKING
WITH BATTERIES. BATTERIES CONTAIN ACIDS
WHICH CAN CAUSE BODILY HARM. DO NOT
PUT WRENCHES OR OTHER METAL OBJECTS
ACROSS THE BATTERY TERMINAL OR
BATTERY TOP. ARCING OR EXPLOSION OF
THE BATTERY CAN RESULT.
1.
When installing new batteries, be sure the
polarity of each battery and overall battery pack
is correct. Due to the electrical characteristics of
this charger, it is possible to improperly hook up
the batteries and not blow the fuse when
charging. Battery and/or charger damage can
result.
2.
New batteries should be given a full charge
before their first use because it is difficult to
know how long the batteries have been stored.
3.
Limit the use of new batteries for the first 20
cycles. New batteries and older batteries that
have been in storage are not capable of their
rated output until they have been discharged
and charged a number of times.
4.
Sulfation results when batteries in storage are
not maintained in a charged, active state.
Internal self-discharge can bring about the start
of this condition in as little as three days in warm
temperatures. Batteries allowed to sit
unmaintained in storage self-discharge, sulfate
to various degrees, and lose capacity.
Repeated charging will generally result in the
recovery of most of the battery's capacity,
though some permanent loss can be expected.
5.
DO NOT EXCESSIVELY DISCHARGE THE
BATTERIES. Excessive discharge can cause
polarity reversal of individual cells, resulting in
