Winter Storage of Batteries
Battery companies are not responsible for battery
damage either in winter storage or in dealer stock if
the following instructions are not observed:
1. Remove battery from its installation as soon as
possible and remove all grease, sulfate and dirt
from top surface by running water over top of bat-
tery. Be sure, however, that vent caps are tight
beforehand, and blow off all excess water thor-
oughly with compressed air. Check water level,
making sure that plates are covered.
2. When adding distilled water to battery, be ex-
tremely careful not to fill more than 3/16 in
.
(4.8
mm) above perforated baffles inside battery. Bat-
tery solution or electrolyte expands from heat
caused by charging. Overfilling battery will cause
electrolyte to overflow (if filled beyond 3/16 in.
above baffles).
3. Grease terminal bolts well with 2-4-C Marine Lu-
bricant and store battery in a COOL-DRY place.
Remove battery from storage every 30-45 days,
check water level and put on charge for 5 or 6
hours at 6 amperes. DO NOT FAST CHARGE.
4. If specific gravity drops below 1.240, check bat-
tery for reason and recharge. When gravity
reaches 1.260, discontinue charging. To check
specific gravity, use a hydrometer, which can be
purchased locally.
5. Repeat preceding charging procedure every
30-45 days, as long as battery is in storage, for
best possible maintenance during inactive peri-
ods to ensure a good serviceable battery in
spring. When ready to place battery back in ser-
vice, remove excess grease from terminals (a
small amount is desirable on terminals at all
times), recharge again as necessary and reinstall
battery.
WARNING
Hydrogen and oxygen gases are produced dur-
ing normal battery operation or charging. Sparks
or flame can cause this mixture to ignite and ex-
plode, if they are brought near the vent openings.
Sulfuric acid in battery can cause serious burns,
if spilled on skin or in eyes. Flush or wash away
immediately with clear water.
Battery Charging System
Description
The battery charging system components are the fly-
wheel permanent magnets, stator, voltage regulator/
rectifier and battery. The rotating permanent mag-
nets induce an alternating current (AC) in the stator
coils. The AC current is rectified to direct current (DC)
by the voltage regulator/rectifier. The DC output from
the voltage regulator/rectifier is used to charge the
battery. The voltage regulator/rectifier also senses
the battery voltage as a measure of the battery’s
state of charge and thereby regulates the DC current
flow to the battery. In this manner, the battery charge
is maintained and the battery is protected from an
overcharge condition.
