This is the reason why it is harder to start a car with a battery that is completely dead. The logic is very simple here is that the dead battery will absorb more of the power. This again serves as another reason to get the jump starter that has the highest cold cranking amp rating, this provides it the best possibility of starting the vehicle with the dead battery. The main purpose of the jump starter-to work when it is needed. Most of the batteries do not last more than two to four years. After that these worn out batteries are replaced by new ones.

How to identify one that can jump start even a dead battery and jump starter that cannot jump start a vehicle having a dead battery?

It is said that the higher the cold cracking amps rating, better the scope of mainly starting a car even with a dead battery. On the other hand, a car jump starter with 500 cold cranking amps should be capable to start any car with a dead battery.

However, this are the things that should be considered in case of car battery jump starter. It is important to follow these steps while trying it.
