4. Important Safety Warning (SAVE THESE INSTRUCTIONS)
CAUTION! The charger is designed to charge the specific voltage lead-acid battery. Please see
the specifications for the acceptable voltage range. Do not use these products on batteries
with other voltage ratings.
CAUTION! Some models may generate high current DC voltage to the battery being charged.
Do not expose the charger to the water, rain, snow or spray.
CAUTION! Do not open the charger. There are no user-replaceable parts inside of the unit.
Attention! Ensure at least 20 cm air space is maintained on all sides of the charger. During
