How to Use a Car Battery Charger

Car batteries are a very important component of vehicles. Taking care of it is a necessity, but it might wear out as well due to certain conditions and habits of its owners. 

Did you know that the more often you have a short trip added with regular on and off will wear out your battery? Of course, winter season adds ups this scenario as there will be frequent use of car heaters, headlights, and wipers. 

In times when your car battery won’t start, you might have a discharged battery, which is also termed as “flat” battery. Avoiding such an untoward situation is possible through using a battery charger. It is not an expensive accessory and a really helpful one. This accessory will use the main current, replacing the lost charge through negative and positive clips to its corresponding battery post. 

Consider the Right Amperage 

While using a car charger with a battery charger is a simple task, there are also a few things you must keep in mind. Always use a charger with the right amperage for the battery that you needed to charge. Experts suggest the use of a smart car battery charger since it has a reverse polarization feature, and it will also prevent overcharging. 

The amperage of battery chargers ranges from 2 to 10 amps. A high amperage output will give a faster charging capacity. For charger with 2 amps capacity, it will usually take about 24 hours to give 48 amps to your car battery; especially, it is totally “flat”. 

Car batteries have 48 amps capacity. Basically, it will charge 1 amp per hour. If you wish to charge your battery at an output of 10 amps, then this is just a quick charging process. After 1 to four hours, make sure to switch off the charger to avoid overcharging.
