Car battery chargers are the Genie to your Alladin. You are stranded in the middle of nowhere. Your car battery is flat and the only help you could get is from someone smart. You could wave off to cry for help but at the same moment, it is frustrating too.

Is it beneficial to buy a car battery charger?

As we look briefly, every car battery contains some proportions of “hydrogen” gas in it. This makes our battery volatile and prone to strong environmental conditions. These are temperature-sensitive and could be easily blown to being flat.

Before reading the below explanation on how the battery charger works, we advise you to take a brief note of your environment. If done, let’s proceed further.

Picking up the right charger

It is a headache to choose the right car charger for your battery. Firstly, make sure the charger is compatible with your car. To get this right you can look out the in the car manual and research your market accordingly.

Car experts suggest that going with medium-range variant good works just fine. Battery Tender Plus 021-0128, Leicestercn EPA1205MT, Leicestercn EPA1020-0612, Clore Automotive Jump-N-Carry JNC660 and NOCO genius G3500 are some of the top-rated portable car battery chargers in 2020.

How does it work?

Every battery charger will come with its power supply. A normal battery charger comes around 48 amp-hours. This means, at full charge, it could supply 1 amp voltage for 48 hours. This can also be divided into different hour ratios such as 2 amp voltage for 24 hours and 3 amp voltage for 16 hours.

Now, we get to our question. The basic plan is to give the boost to your battery so it comes back to life. Before connecting your battery charger, check the electrolyte levels and fill it up, if empty. Brush out the dirt and grease from the front posts of the battery.

Also, if your car has an alternator, remove it before plugging in the charger. A voltage supply of direct current could damage your alternator. Connect your positive (+) lead from the charger (red-colored), to the positive battery post. Simultaneously, connect the negative (-) lead from the same charger (color black) to the negative terminal.

Now, portable battery chargers will show the meter reading. This will be sudden at first but as charging continues, the charging rate gradually decreases. Also, a gauge will be present on the charger which will notify you when the charging level is at 100%.


Make sure you are around while charging your battery. Watch out for gassing during the final moments of your charging. If it occurs more frequently, try taking it to a specialist as it can be defective.
