Car Battery Charging Time – Calculator and Inverter

Car Battery Charging Time – Calculator and Inverter

Page view

  Newer battery chargers are being made with newer battery technologies. Not only is the battery technology improving but the charging technology is getting smarter day by day. With all of this improvement, it is necessary to know how long it will take to charge the car battery as you are looking to stay away from issues as much as possible.

  Car Battery Charging Time Calculator

  Although there are a lot of battery charging time calculators available online, you still need to know a lot of things in this regard. So, here is all you need to know about the battery charging time calculator.

  The information collection part.

  There are three main things that you need to know when you are going to calculate the car battery charging time. Those things are explained below in detail and how you can find the values for those.

  Battery Capacity

  The first thing that you need to know about the battery is its capacity. The capacity can be either found on the booklet of the battery or that of the car. Otherwise, it may be written on the battery itself, but it is not the case with all batteries. A clue for finding the value is that it is written with the unit: Ah(amp-hour)

  Amps of the Car Alternator

  Knowing about the amps of the alternator is also important as it is the part that is going to charge the car battery. The amps of the alternator can be searched by the model of your car. It is written with the unit: A(amps/ ampere)

  The Voltage of the Car Battery

  The last thing you need to know is the voltage of the car battery. It will be significant to tell you whether the battery is good for charging, or if you need to replace it. You can easily check it with the voltmeter.

  How to implement the car battery charging calculator

  Take the battery capacity and then divide it with the amps value of the alternator. In this way, you will get a value in hours. This value will be the time that is needed to charge the car battery. You can also convert it into minutes if the value is in points.

  Car Battery Charging Time After Jump Start

  In some cases, the car is left with a dead battery that needs to be charged but there is no way you can charge that battery. In that case, the only help you have is another donor car that helps you by jump-starting your car. So, now that your car has started, how long must you leave it before turning off the engine?

  The time engine must be running after a jump start.

  If you have started the car using the jump start method and now you are looking to charge the battery, then you must leave the engine running for at least 30 minutes to an hour. After that time, you can turn off the engine and the battery will stay charged with the help of future trips [s if you frequently use your car.

  Taking the car on a ride right after jump-starting it.

  Some people think that during this time you must not use the car. Well, it is a misconception. When the car runs there is almost no issue with the charging of the car, but you can say that the charging process may get better according to the specifications of the alternator.

  So, if you are taking your car for a ride then make sure that the ride lasts for at least 30 minutes, and you are not running the car at very low RPM. In this way, the engine of the car will be able to charge the battery in a very efficient manner.

  If you are going to leave the car running for 30 minutes but then you are not going to use it for a long time again then there is no benefit of keeping the engine on for 30 minutes. In that case, you can use a trickle charger for the better health and performance of the car battery.

  Car Battery Charging Time With Inverter

  So, you have a power backup system that is used for keeping your home electronics working in the case of a power cut. Well, you may see the voltage rating being the same on the inverter of that power backup system, and in the case of a dead car battery, there could be an idea about using that inverter for charging your car. Well, it is completely possible. You only need to take care of a few little things to stay on the safe side.

  The Charging Time

  If your inverter is supported for charging the car battery, then it will take somewhere between 1.5 hours to 3 hours to fully charge the car battery. The reason behind this efficient charging rate is that most inverters are made for similar types of batteries, so the caring process is pretty much similar.

  Things to care for when you are using an inverter for charging the car battery.

  You need to take care of the following things when you are charging your car battery with the inverter.

  Inverter Type

  The first thing is the inverter type. Although the inverters work with more than one battery, there is usually a switch for switching between one or two batteries. You need to make sure that the inverter is either for one battery or has the switch for using only one battery.

  Charging Current

  The next thing will be the charging current. It can vary a little but if there is a major difference then it is not the safest to use the inverter for fully charging the battery.

  Battery Temperature

  Keeping track of the battery temperature while charging is important. If the temperature exceeds too much, then it is better to stop the charging process.

  This will be the safest way to charge your car battery with an inverter.

  Conclusion

  Getting to know about the charging time of your car battery can save you in a lot of ways from being late. So, we hope that you now know how much your car battery will take to charge in different ways. Now you are also able to calculate the charging expected time for your battery.
