A car emergency start battery can be a lifesaver when your car battery dies. Most people focus on output voltage or portability, but input voltage is just as important. In this article we’ll explain what input voltage is, why it matters and how to choose the right jump starter for your vehicle.
What Is Input Voltage?
Input voltage is the electrical power required to recharge the emergency start battery. Usually input voltage is between 12V and 15V. Make sure your jump starter has the right input voltage for battery health and quick recharge when you need it.
Why Input Voltage Matters
Input voltage is important for:
-
Charging Speed: Higher input voltage means faster charging, less time to recharge the battery.
-
Battery Life: Using the wrong input voltage can shorten the life of your jump starter. Make sure you have the right voltage for battery health.
-
Compatibility: Ensure your jump starter’s input voltage matches the power source you’re charging it from, whether at home or in your car. Most jump starters can be charged from a wall outlet or a car’s charging port.
How to Choose the Right Input Voltage
Here are a few things to consider when choosing the right car emergency start battery:
-
Check the Battery’s Spec: Always check the manufacturer’s instructions to confirm the input voltage. Most car emergency start batteries recharge at 12V, but some may need a higher voltage.
-
Your Charging Source: If you charge your jump starter in your car, make sure the input voltage matches your vehicle’s charging system. Portable jump starters that charge from 12V car sockets are common, but a higher voltage option may be better for faster recharging at home.
-
Versatility: Some car emergency start batteries come with multi-voltage input options. This allows you to charge the battery from different power sources, providing added flexibility. This is handy for frequent travelers or those who need multiple recharging options.
Extra
Besides input voltage, look for:
-
Overcharge Protection: Prevents the battery from getting too much voltage and extends its life.
-
Fast-Charging: Some models have fast-charging feature which reduces recharging time.
-
Portability: A compact design for easy storage and access during emergencies.
Bottom Line
A car emergency start battery with the right input voltage ensures a fast recharge. It also extends the battery's life and increases compatibility with different power sources. A good jump starter keeps you ready for emergencies, worry free.
