Best Car Jump Starters Buyer’s Guide & Reviews

The booster cables and discharged battery,Charging battery car with electricity trough booster jumper cables.

Everybody that drives has car issues. Particularly individuals who have purchased older cars for economic reasons. When I was in my first year of college, I had an old Nissan Micra and driving there every morning was always a gamble.

I used to dread getting up in the morning and facing my routine of getting ready and hoping that my car would just start on that day.

Sometimes, it did without a problem; whilst a lot of the time it would struggle or not start at all. This daily dilemma would leave me searching for the nearest bus or the dreaded phoning a friend to jump-start your car.

So What’s The Solution?

For some people whose cars will not start, jump-starting the car can be a remedy. This method of starting a car involves using another battery.

It temporarily connects two power sources which will start the battery and subsequently the engine.

This problem is usually attributed to a discharge in electricity which is normally recharged when the driver simply drives their car after the jump start has taken place.

When you need to jump-start your vehicle you will, first of all, require jumper cables.

Your vehicle should have its engine switched off with both vehicles’ handbrakes on to ensure safety.

The clamps should be attached to their appropriate terminals and the jump-starting can begin.

It is recommended that if the jump start is successful then the beneficiary of the jump start should drive their vehicles around for approximately fifteen minutes in order to fully recharge the battery.

If the car starts again after the battery recharges then that is the ideal outcome with the problem being solved.

However, sometimes this is not the case and the car will not start again. This usually means that the battery is no longer holding a charge and that it most likely will need replaced.

How Useful Are They?

Drivers around the world have jumper cables to enact this very method of fixing their car.

These are cables that are made of insulted wiring with clips on the end of them to connect the corresponding car batteries together.

However, despite this they do have limitations such as not being able to connect different levels of voltage e.g. twelve volts and six volts together may cause damage.

Also, if the battery that’s being jump-started happens to be frozen, damaged or has a low electrolyte level; or is decayed then the battery can potentially explode.

Besides from the technical issues presented the most glaringly obvious problem is that aside from owning jumper cables you will need another car to actually jumpstart the vehicle.

While some individuals may have colleagues, friends or family etc that are willing to do this most people are in a rush when trying to start their car and don’t have the luxury of waiting around.

This is where portable batteries shine.
