CHARGER FOR LEAD-ACID BATTERIES, WARNING :
To disconnect the power-supply, before making the connections or disconnections
on the battery.
To use inside a room or to protect from rain.
Protection against polarity inversions by fuse (F1).
Explosive gas, to avoid flames and sparks. This battery charger includes parts, like
switches oder relays, which can cause arcs or sparks. Therefore, on charging a
battery in a garage or in a similar room, to keep the charger apart if necessary.
