SAFETY INSTRUCTIONS, INJURY OR PROPERTY DAMAGE CAN OCCUR.
INTRODUCTION
The Lestronic II battery charger is designed to
recharge deep-cycle,
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.
PUT WRENCHES OR OTHER METAL OBJECTS

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.
