Batteries emit explosive gases during charging. Charging areas should be well ventilated.
Wear safety glasses when working on and around batteries.
Hydrogen gas occurring in batteries is highly flammable. Keep inflammable factors such as sparks, flames, lit cigarettes, welding, friction and static electricity discharge away from batteries.
Otherwise gas may inflame and explode.
When disconnecting a battery from a vehicle, negative (-) terminal post must disconnected first while positive (+) terminal must be connected first when connecting again.
Do not connect or disconnect circuits directly during charging. Always turn off charging and testing devices before connecting or disconnecting cables to prevent sparks.
Flooded batteries should not be tilted more than 45 degrees to either side. Batteries contain sulphuric acid which may cause serious burns, in case of contact with acid, wash the affected area with plenty of water. In case of eye contact, wash and immediately seek for medical help.
Before charging a frozen battery, wait until it warms up to 15 degrees.
Do not install the battery to a vehicle unless you can confirm the battery voltage is in right direction.
Keep batteries and electrolyte away from children.
Read and follow the instructions.
When starting a vehicle with jumper cable; connect positive (+) terminal cables of both batteries first, then connect the other cable to negative (-) terminal of tow truck and faulty vehicle. Connection should be made as far as possible from the case where ground cable is connected. Apply the exact opposite procedure after the vehicle starts.
