How can a battery charger blow up?

Car batteries are also known as a lead-acid because they use plates of lead caused by sulfuric acid to keep and minimize electrical energy.

This technology has been used since the 18th century and it is not extremely effective from the energy from weight to volume position.

Nonetheless, they still have a good power-to-weight percentage. It means that they have high-quality at giving the high levels of current demand by automotive beginners.

If you link the negative jumper cable to the battery itself, any possible hydrogen amount could be exploded by the next spark. It is better to wait a few minutes to turn on until the charger is connected.

The second reason comes from the inside battery even if the ignition source is still hydrogen gas. The problem is that if a battery is not truly maintained and the electrolyte level can drop, the lead plates will go with oxygen and the shape is curved.

This probably happens the touching and plates flexing during the drain when you begin the motor, which enables to make a spark in the battery charger. Hydrogen in the battery ought to wake up to cause an explosion at any time.

  •    Step 3: Take the similar cable to the positive terminal of the dead battery
  •    Step 4: Put the other jumper cable to the negative terminal of the donor battery
  •   Step 5: Get the other end of the cable to bare metal on the engine or frame of your car with the dead battery

Some elements in the car battery charger you should know
