Debugging, maintenance and maintenance car battery

Avoiding risks of sparks

  • Ensure that consumers are disconnected before reconnecting disconnection or car battery.
  • When charging, stop the charger before connecting or disconnecting the battery.
  • Do not put metal objects on the battery to avoid creating a short circuit between the terminals.

Plugging a charger

  • Charger should be compatible with a car battery voltage nominal 12 Volts.
  • Disconnect mandatory (engine off) cables connected to the two terminals of the battery starting with the negative terminal.
  • Do not disconnect the car battery when the engine is running. According to data provider use charger car battery you use.
  • Only a well-charged battery and well-maintained car can reach a maximum life and allows you to start your vehicle’s engine normally.
  • The battery must be kept clean and dry.


Check frequently the state of battery charge you:

  • Especially on short-distance vehicle use, specifically in urban traffic.
  • When the outside temperature decreases (during the winter), state of charge drops. In winter, do not use electrical equipment than necessary.
  • Finally know the state of charge normally decreases due to certain “permanent consumers” such as the clock, after sales accessories, etc.

If many accessories are fitted to the vehicle, connected to + after contact them. In this case, it is desirable to equip your vehicle with a car battery nominal capacity higher. Seek advice from your driver.

In the event of a prolonged operation of your vehicle, disconnect the battery or recharge it periodically, especially in cold weather. It is necessary to reprogram memory devices, car radio, etc. Car battery must be stored in a cool, dry place and away from frost.

Some batteries may present certain specifications recharge. Avoid the risk of sparks which could trigger an immediate explosion and charge the battery in a well-ventilated place.

Start with a car battery of another vehicle

To start, you should receive power from a car battery of a vehicle, proceed as follows:

  • purchase extra cables suitable or if you already have cable starter, make sure you are in perfect condition.
  • The two batteries must have the same nominal voltage: 12 volts.
  • Capacity battery that supplies power should have a capacity (amp-hours, Ah) at least equal to the battery capacity.
  • Make sure there is no contact between the two vehicles (risk of short circuit when the positive terminal binding) and the empty battery is well connected. Turn the ignition of your vehicle.
  • Start the engine of the vehicle providing current and adopt a medium speed.
  • Fix the positive cable (+) A to the Positive (+) battery capacity, then the Positive (+) 2 of the battery supplying the power.
  • Fix the negative (-) terminal B (-) of the battery supplying the current then Negative (-) 4 of the battery capacity.
  • Check that there is no contact between cables A and B and the A (+) is not in contact with any metal part of the vehicle providing current.
  • Start the engine normally. Once it starts, disconnect the cables A and B in reverse order.

Handle carefully a car battery as it contains sulfuric acid which must not come into contact with eyes or skin. If such contact occurs, wash thoroughly with water.
