Do not know how long it takes to charge a car battery? Don’t worry, we tell you.
Mainly, you need to know that the time you use in recharging will be linked to the operation of your car, whether it is a synchronous or automatic model. Here you can read more about the car battery charger.
To charge the car’s battery at home
It will be very useful to know how to calculate the time to load by hand with any type of cargo dispenser, you will only have to use the following formula, so you can know how long it takes to charge a car battery:
TC (in hours) = Battery Ah) / Charger Ah
TC = loading time
Ah = refers to the measure of milliamperes
But many things depend precisely on a battery charger and if you still do not have a better battery charger, you have to buy one and be sure you can always start your car.
The formula presented above can be taken into account if you are going to charge the car’s battery with charger and do not have the necessary devices to measure the level of charge and efficiency that your battery currently has, the way in which you do the charging will be crucial for It’s done correctly, so you’ll have to know how to charge the car’s battery properly.
On the other hand, if you have knowledge of the level of charge and efficiency that your battery has, you can use the following formulas depending on the case, let’s see below:
- Loss of efficiency of 10% TC = (C / IDC) * 11) / 10
- Loss of efficiency of 20% TC = (C / IDC) * 12) / 10
- Loss of efficiency of 30% TC = (C / IDC) * 13) / 10
- Loss of efficiency of 40% TC = (C / IDC) * 14) / 10
- If there is no loss of efficiency TC = (C / IDC) * 10) / 10
- TC = is the loading time
- C = battery capacity
- IC = load index
These formulas also work if you want to know how long it takes to charge a motorcycle battery.
On the other hand, it is important to evaluate that there are many elements that will mark the time your battery lasts in charging, let’s see some of them:
It is important that the battery has enough voltage (measured in amperes) to start, allowing the engine to start when the ignition is activated. Keep in mind that batteries can last up to five years, where their time of operation depends on their quality and warranty.
- The alternator:
This important part of the system, since it allows to maintain the optimum charge of the battery once the vehicle is in motion. If the alternator is not working properly, it can affect the charging time of the alternator.
- The charger that you use:
Last, but not least, in the process of charging a battery is the type of charger that is used to know how to charge the car battery in the best way possible, keeping in mind that the configuration that has the charger is crucial to define the time and the process of charging the battery.
How to charge a car battery is not a difficult job to achieve and calculate how much time it takes to do much less, but remember that it will depend on the quality of the battery to recharge and the charger and the tools you use to achieve it.
