How Long Does It Take to Charge a Car Battery with a 12-Volt Charger?

If you have been wondering how to charge a completely dead car battery, then this article will help you. I have worked with cars for many years, and I know almost everything regarding questions like how to recharge a car battery. There are plenty of options for diverse battery chargers available on the market. Down below, you will get to know about charging a car battery with different amperage and the time needed in each case

Besides, I have provided the list of the best chargers for transportation that you can consider purchasing with their main pros and cons. Let’s get started to find out more.

How to charge a car battery, and how will it take with different amperage? You will find the answer below.

What Time Is Required to Charge Transportation at 40 Amperes?

This power is more than enough to recharge a car battery very quickly. By using 40 amperes, you will be able to start your automobile within a few minutes, even if the battery was completely dead before. There are plenty of options available so that it will be suitable even on the road. In case you need to charge a battery fast and jump start it, this amperage will suffice. However, you have to be attentive not to overcharge your transportation. Otherwise, it can seriously damage the battery, so don’t leave it connected for a long time or use a smart charger that will reduce the amperage.

What Time Is Required to Charge Transportation at 2 Amperes?

With this amperage, it will require more time to charge a battery. 24 hours is the average time required to charge a battery fully. How come? It’s worth mentioning that the majority of batteries are 48 amperes, and it takes approximately one-ampere charge per hour. Respectively, with this amperage, you will get a full battery only in one whole day. Often, this amperage is used if you want to maintain your battery at some level.

It won’t be suitable to jump-start transportation or recharge it fast. In case you don’t use your transportation often, you can use this power and leave the charger connected.

What Time Is Required to Charge Transportation at 4 Amperes?

As I have already written above, your battery will charge at 1 ampere per hour and, respectively, with this amount, you will be able to charge your auto or motorcycle in approximately 12 hours. This power is still quite low and won’t be suitable for a quick charge. Nevertheless, it’s completely perfect for motorbikes or other smaller batteries. 

Choose this option if you want to maintain your battery or when you are ready to charge at a low amperage for a long period. Once again, it will be suitable for those who don’t use transportation very often.

What Time Is Required to Charge Transportation with a Trickle Charger?

trickle charger works at 2 amperes, and it will take too much time to charge an automobile. The whole day is estimated time for recharging a transportation battery. In case it’s completely dead, more time may be required. This type is used mostly to maintain a certain level of charge on a battery to make sure it won’t run out. The system will automatically switch it off once a battery is full. In most cases, trickle chargers are used by professionals in a workshop to perform some mechanic works.
