10.8 Replacing the Battery
Risk of injury due to short-circuit currents
Short-circuit currents in the battery can cause heat build-up and electric arcs. Burns and eye injury 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.
Danger to life due to incompatible lithium ion-battery
An incompatible lithium-ion battery can lead to a fire or an explosion. With incompatible lithium-ion batteries, it is not

–Sony
This list is updated regularly (see Planning Guidelines "SMA Smart Home" at www.SMA-Solar.com).
Chemical burns and poisoning caused by battery electrolytes
If handled inappropriately, battery electrolytes can cause chemical burns to eyes, respiratory system and skin, and be
poisonous. 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,
