CHARGING & STARTING SYSTEM
90-855347R1 JANUARY 1999 Page 2B-5
2. When adding distilled water to battery, be extremely careful not to fill more than 3/16
in. (4.8 mm) above perforated baffles inside battery. Battery solution or electrolyte ex-
pands from heat caused by charging. Overfilling battery will cause electrolyte to over-
flow (if filled beyond 3/16″ above baffles).
3. Grease terminal bolts well with 2-4-C Marine Lubricant 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 battery for reason and recharge. When
gravity reaches 1.260, discontinue charging. To check specific gravity, use a hydrom-
eter, which can be purchased locally.
5. Repeat preceding charging procedure every 30-45 days, as long as battery is in stor-
age, for best possible maintenance during inactive periods to ensure a good service-
able battery in spring. When ready to place battery back in service, remove excess
grease from terminals (a small amount is desirable on terminals at all times), recharge
again as necessary and reinstall battery.
