Danger to life due to explosive gases
Explosive gases may escape from the battery and cause an explosion. This can result in death or serious injury.
• Protect the battery environment from open flames, embers, or sparks.
• Install, operate, and maintain the battery in accordance with the manufacturer's specifications.
• Do not heat the battery above the temperature permitted or burn the battery.
• Ensure that the battery room is sufficiently ventilated.
Chemical burns and poisoning due to battery electrolyte
If handled inappropriately, battery electrolyte can cause irritation to the eyes, respiratory system, and skin, and it can
be toxic. This may result in blindness and serious chemical burns.
• Protect the battery enclosure against destruction.
• Do not open or deform the battery.
• Whenever working on the battery, wear suitable personal protective equipment such as rubber gloves, apron,
rubber boots, and goggles.
• Rinse acid splashes thoroughly with clear water and consult a doctor.
• Install, operate, maintain, and dispose of the battery according to the manufacturer's specifications.
Risk of injury due to short-circuit currents
Short-circuit currents in the battery can cause heat build-up and electric arcs. Burns or eye injuries due to flashes may
result.
• Remove watches, rings, and other metal objects.
• Use insulated tools.
• Do not place tools or metal parts on the battery.

Risk of burns due to hot battery components
Improper battery connection may result in excessively high transition resistances. Excessive transition resistances give
rise to localized heat build-up.
• Ensure that all pole connectors are connected with the connecting torque specified by the battery manufacturer.
• Ensure that all DC cables are connected with the connecting torque specified by the battery manufacturer.
