Battery electrolyte contains sulfuric acid, which
is poisonous and can cause severe burns.
Swallowing electrolyte can be fatal or if it touches
skin can cause severe burns.
• Wear safety glasses to shield eyes, and rubber
gloves to protect skin and clothing when
handling electrolyte.
• Do Not swallow electrolyte.
• In the event of an accident, flush with water
and call a doctor immediately.

period without recharging them will result in
reduced performance and service life. To preserve
optimum battery performance and life, recharge
batteries in storage when the open circuit voltage
drops to 12.4 volts.
