![]() ![]() In reality, the amount is not exactly 12 volt. In fact, 12 volt is just a term used to distinguish one battery from another. What voltage should a 12 volt battery read when fully charged?īelieve it or not, but a 12 volt battery should not be read with 12 volt to see if it’s fully charged or not. To avoid all the unnecessary trouble, it is best to use chargers that do not pose a risk for the batteries, and those chargers must be in line with the formula provided by the manufacturers. We can also use smaller chargers, but it will eventually burn up as it takes longer to charge the battery. However, it should be noted this method poses the risk of decreasing the battery’s life. If you would like to decrease the amount of charging time, larger chargers are allowed. This does not mean that the chargers cannot be larger, or course. For example, we have a 100 ah and 12 volt battery, so we will need 25 amp for the battery, as 25 is the 25% of the ah. They recommend us to have 25% of the battery’s capacity. Using the battery’s capacity (ah and volt). Now here comes the main part: how many amps are needed for charging if we have a 12 volt battery? Manufacturers have provided a formula that allows us to measure the amp easily. ![]() From here, we can learn how amperage plays a big role and should be measured carefully. The trickle poses no danger since the amount is little, but if the amount is large, it can be threatening since you can drown in it even when the speed is slow. So if there is a small waterfall with a trickle of water, the water would be the amperage, while the speed and position of the waterfall is the voltage. Volt is basically the speed or steepness of the river, while the amp is the amount of water the river has. Let’s use a river as an example for amp and volt. Meanwhile, amp, or amperage, is the amount of electrons itself. In simpler terms, volt, or voltage, is the amount of pressure that’s needed to let the electrons flow. How many amps do you need to charge a 12 volt battery?īefore we delve into details regarding the amount of amps needed for a 12 volt battery, let us differentiate amps and volts first. For this reason, we will be discussing them today, in specific things related to amps, full charge, and power supply for a 12 volt battery. Therefore it is important for us to know terms such as amps, volts, and how they are applied to batteries. As we need batteries for daily activities, it is necessary for us to know the basics of it and how to maintain it properly. ![]()
