Charging batteries may be hazardous, especially when connecting the battery charger to the battery.
Connecting the wrong polarity (red/+ to black/-) may cause a short-circuit which could result in explosion of the battery.
Connect red/+ to red/+ and black/- to black/- and always follow manufacturer’s operating instructions for charging.
- Ensure the battery charging unit is de-energized before making your connections.
- Once the connections are made, turn on the charging unit.
