CHARGING TIPS ..
Always leave filler caps in place, tight and secure to reduce the risk of battery explosion and serious injury! Always wear safety glasses when working around
batteries. Batteries can explode! Protect your eyes. Do not charge batteries without proper instruction. 1. Batteries should be charged if hydrometer reading is
below 1.225 specific gravity, or open circuit voltage is below 12.4 volts, or if the first load test is below 9.6 volts as noted previously.
2. Carefully read and follow the instructions that came with
the charger to avoid serious injury, property damage and/or battery damage.
3. Unplug the charger before connecting or disconnecting
a battery to avoid dangerous sparks which can cause a battery to explode.
4. Do not leave a battery on charge for more than 48 hours
to avoid damaging the battery by over-charging. If gassing or spewing of electrolyte occurs, or the battery case feels hot, reduce or temporarily halt charging to avoid damaging the battery.
5. Stop the charge when two hydrometer or voltage read-
ings recorded two hours apart indicate no increase. Further charging would be useless and may damage the battery and shorten its life. If the battery won't come up to full charge, replace it.
6. NEVER attempt to charge a frozen batter
y. To avoid
explosion and serious injury, allow it to warm to 60°F (16°C) before charging.
7. NEVER
leave a battery on a trickle charger longer than
48 hours. Serious damage to the battery WILL occur. NOTE: Times are approximate and depend upon battery condition, age and design, the efficiency of the charger, line voltage and other factors.

California Proposition 65 Warning
Batteries, battery posts, terminals and related accessories contain lead and lead compounds, and other chemicals known to the state of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
OFF-SEASON STORAGE ..
Batteries that are not in use during the off-season must be cared for as follows to extend battery life and reliability: 1. Disconnect the batteries to avoid self-discharge due to
parasitic loads such as clocks, ground faults, etc.
2. Put into storage fully charged and keep them above 75%
state-of-charge. Check state-of-charge every 90 days and recharge if necessary.
3. Ideally, store batteries in a cool, dry place with temperatures
not below 32ºF (0ºC) or above 80ºF (27ºC). Typically, batteries will self-discharge at faster rates at higher temperatures. For example:
TEMPERATURE SELF-DISCHARGE RATE
100ºF (38ºC) . . . . . .3 Pts. Specific Gravity per day
80ºF (27ºC) . . . . . .2 Pts. Specific Gravity per day 50ºF (10ºC) . . . . . .1/2 Pt. Specific Gravity per day 30ºF (–1ºC) . . . . .1/10 Pt. Specific Gravity per day
NOTE:
This is only an example. Self-discharge may be higher or lower depending upon battery chemistry, lead alloys, age and other factors.
