Get 12v Lithium Car Battery As a Power Source for the Ride

By Gerald, Updated on April 30, 2024

Every passing day, the automotive industry is embracing advancement in every aspect. The same case applies to the battery compartment of the vehicles. Now, traditional lead-acid batteries have become old-fashioned with many flaws. At the same time, a 12 volt lithium car battery is the alternative solution to all the battery problems. The compelling features make it the first choice for everyone. You can expect from a 12 volt lithium car battery a long lifespan, fast charging, and lightweight and maintenance-free abilities. So today, we are going to dive deep to explore everything about the 12 volt lithium battery which will help to choose the right battery for your car.

Part 1. What is a 12 volt lithium battery?

A battery that utilizes lithium ion technology to store and deliver a 12-volt electrical power is known as 12 volt lithium battery. The power rating of 12 volts makes the lithium battery ideal for most electrical devices, especially vehicles. It functions to crank the engine and deliver the power to the electrical instruments of the cars.

There are two common types of lithium car batteries: 12v power density. The first one is Lithium Ion Phosphate (LiFePO4), the most famous one. It offers stability, safety, and long lifespan, making it a reliable choice for every car. The second type is Lithium Nickel Manganese Cobalt Oxide (NMC) which provides high-power delivery within a compact size. However, it is a bit expensive compared to LiFePO4 and sensitive to extreme temperatures.

Part 2. How long does the 12 V lithium car battery last?

A 12 volt lithium car battery can last up to 3 to 5 years. If used with extra care, it can last 5 to 7 years. A 12 volt lithium polymer car battery (LiPO) battery provides a lifespan of around 300 to 500 charge cycles. After completing its charge cycles, it starts to lose efficiency.
Whereas, a 12 volt lithium car battery (LIFePO4) provides more than 2000 charge cycles. So you will not have to replace the battery frequently. Several factors contribute to the life of a 12 volt lithium battery.

Charging cycles: The primary factor affecting a lithium battery’s lifespan is the many charging cycles it goes through.
Depth of discharge: Always aim to stay between 50% to 100% battery level because deep discharge can shorten the battery life.
Extreme temperatures: A normal temperature guarantees a long lifespan of the 12 volt lithium car battery. Excessive heat or cold can damage the battery and reduce its lifespan.

Part 3. 12 v lithium car battery VS 12 V lead acid battery

If you are thinking of installing a 12v lithium battery for your car. In that case, it means you will get some compelling benefits with this change. Compared to a traditional 12 volt lead acid battery, a 12 volt lithium car battery is improved in almost every aspect. Here are the key differences between the two batteries.
1. Improved fuel efficiency

Lithium ion batteries come with high energy storage compared to traditional lead-acid batteries. A 12 volt lithium car battery is 60% lightweight. That means you will make your car lightweight and will get some good fuel mileage.

2. Increased performance and power delivery

Not only do lithium batteries improve fuel efficiency, but they also provide high torque and stable performance on the road. With the high and constant energy of a 12v lithium battery car computers and electrical instruments will perform at their peak.

3. Better suited for extreme weather conditions

The primary purpose of a car is to crank the engine to give it starting power. But it becomes hard to start the car in cold weather. A traditional lead acid battery has lower cold cranks. However, a new advanced 12 volt lithium car battery has high cold cranks and high energy density, making it easier to start the car in cold weather.

4. Reduced maintenance requirements

Installing lithium car battery 12v means getting rid of frequent topping up of fluids like lead-acid battery needs. Once you have installed a lithium battery in a car, you will not need to worry about maintaining the battery for many years.

Part 4. How to charge a 12 volt lithium car battery?

A proper charging of a 12 volt lithium car battery guarantees a long life and battery efficiency of the battery. Therefore, having the proper knowledge to charge 12v battery becomes compulsory for everyone to learn.

Step 1. Ensure the charger is unplugged from the power to avoid any electrical shock or short circuit.
Step 2. Now connect the charging clamp positive (red) to the positive terminal of your battery, marked with a plus sign (+). At the same time, the negative clamp ( black or blue) to the negative terminal is indicated by a minus sign (-).
Step 3. After making the right connections, double-check the clamps plug the charger into the power socket, and start charging a 12 volt lithium car battery.

Try to keep an eye on the charging process of a 12 volt lithium battery. If the battery is overheating, immediately disconnect the power from the charger. Moreover, the battery must be charged at a well-ventilated place because the charging process generates some heat.

Part 5. Buy the 12 volt lithium car battery

Here are some considerations you should keep in mind while buying a new battery for your car.

1. Higher Initial Cost Compared to Lead-acid Batteries

You should understand that a lithium car battery 12v is a bit expensive. It is 3 to 4 times higher in price. However, this expense will be compensated in the form of a longer lifespan compared to lead-acid batteries.
2. Choosing a Reputable Brand

A good battery heavily depends on the build quality. Therefore, choosing a reputed brand that provides quality within a suitable price bracket is important. Ufine Battery is one of the reputed brands that provides a 12-volt lithium car battery, ranking third.
3. Battery Management System (BMS)

Before buying, you should know the Battery Management System (BMS). It is a built-in battery circuit that works as a safety barrier. It controls charging ampere, overcharging cut-off, and overheat protection. Choosing a 12 volt lithium battery with BMS is an ideal choice.
4. Compatibility With Car’s Charging System

Consider the car’s needs, like the size, amperes, and volts, before installing a 12-volt lithium car battery. To check the battery’s compatibility with the car, you can get the help of a technician, user manual, or previous car battery. You must take time to verify everything before installing a new 12 volt lithium car battery because a wrong model of the battery can cause discharge, bad cranking, or low electrical voltage problems.
