# Can you use a 24 volt battery in a car?

Contents

The same principle holds for a 24V battery bank in that it provides 24 volts. As we discussed before, most car and RV batteries are 12V. … We sometimes use 24V battery systems in larger trucks and busses due to the vehicle’s higher power needs and long cable runs.

## Can I use a 24V battery instead of 12V?

In an electric vehicle the power usually comes from the battery, and is converted by the motor into energy. Electrical power is volts multiplied by amps so that 40 amps from a 12v battery is 480 watts. … so a 24v system is always better than a 12v system – provided you can physically fit two batteries.

## Can you jump start a car with 24V?

Find someone with a 24-volt system in their car or truck to come help you. Their electrical system can safely be connected to yours with jump leads without risking an overload as your vehicle starts. … They are large, rectangular plastic boxes with two large electrical contacts on them.

## Can you jump start a 12V with a 24V?

Jump-starting a 24-volt system from a 12-volt system won’t work if only one 12-volt battery is available, but if the 12-volt truck has two batteries, it becomes possible to produce a 24-volt supply.

## What is the advantage of using a 24 volt electrical system over a 12 volt?

24 Volts: Advantages

Using a 24 volt supply instead of a 12 volt supply greatly reduces the wiring cost to almost half the original cost. This is so because increasing the voltage of a system causes a reduction in the current through it, and in turn reduces the size of the wires you need .

## Will 24 volts hurt a 12 volt system?

For 12 volts in a 24 volt system use the positive and negative from the same battery to get 12 volts it does not matter how they are wired. like mentioned it can be done but it isn’t recomended.

## Can you charge a 24 volt system with a 12 volt charger?

This requires only one bank of a 12V charger to be attached to the positive terminal of the first battery, and the negative terminal of the second battery. In the second example, to charge a 24V system simply use each bank of the charger on each 12V battery terminal leads.

## What happens if you charge a 12 volt battery with 24 volts?

#12. Yes, if you regulate the voltage down to the right amount. If you just plug a 12 volt a battery into a 24 volt charger it will die in a matter of hours.

## How do you know if your car is 12V or 24V?

The most common method for building a 24V system is to run batteries in series. Running batteries in series means they have a single electrical path equal to the sum of the system’s volts. So, if you have two 12V batteries wired in series, then 2x12V=24V.

## Why does the military use 24 volt?

The voltage that is used for Military radios happens to be 24 volts! We have a winner! According to the mililtary documents from the 1940s (and this should be correct!), the reason for the 24 volt electrical system was to ensure radio compatibility.
