Attention
The battery gives off explosive gases; never
cause sparks or allow naked flames and cigarettes
near the battery. When charging the battery, ensure
that the working area is properly ventilated and that
ambient temperature is below 40°C. Never try to
open the battery: it does not need to be filled with
acid or other types of fluids.
