Comparison study of 6v vs 12v battery

What are 12v batteries used for

Electric vehicles:
12 voltage batteries will give more ampere capacity can deliver uninterrupted power for long hours, these batteries are used in electric vehicles, such as golf carts, scooters, wheelchairs, etc. But in most cases it is more convenient to use the 12v battery directly.

Most recreational vehicles use 12v batteries for their electrical power requirements. As the vehicle requires continuous powering, the energy storage is not enough to meet its requirements.

Instead of using one 12v battery, if they can change to two 6v batteries, the RV can get the same amount of amp power for an extended period because 6v batteries can run longer ampere-hour subject to the cell’s capacity. But there is a disadvantage too. Using two 6v batteries will consume more space. So, in that point of view, a 12v lithium-ion battery is preferred over two 6v batteries when comparing a 6v vs 12v battery.

Home energy storage:
Since the 12v battery can deliver seamless power for an extended period, it can effectively operate as a power bank because of its significant storage feature. Its deep-cycled technology lets the battery recharge frequently and drain without damaging the battery life. 12v battery is an excellent option to use as a home energy storage to back up the electric power requirement.

In various 6v vs 12v battery surveys on power bank usage, we can find that 12v has more acceptance because of its power storage capacity.

In addition, you can use a 12V battery for backup flash power, electric scooter, electric wheelchair, power garden houses, powering trolling motors, solar power storage, a portable power device for your laptop, powering surveillance and alarm system, powering entertainment units, etc.

How many amp-hours does a 12v battery have

Before we answer the question, let us understand the amp-hour. It is the measurement of amperage a battery can deliver in an hour. The ampere of a battery depends on the chemistry technology used for the battery. Different manufacturers use different technology.

Hence the ampere-hour of a lithium-ion battery varies. On average, a 12v battery will have 20-600 Ah. Car batteries with 12v will have 40-100ah, and deep-cycle RV batteries will have 100ah.

Does 6v vs 12v battery produce DC or AC

All battery-operated electronic and electrical equipment works on DC electricity. When AC electricity is used to charge the battery, the electricity will be stored as DC electricity. The DC electricity will not change its direction.

What is the difference between a 6v vs 12v battery

The main difference between a 6v vs 12v battery is that a 6v battery will have 2 cells, and each cell will be producing 3.2voltage, making it 6v. A 12v battery will have 4 cells, and they combinedly produce 12v.

Better longevity: The longevity always depends on the battery chemistry and material used for the cells. If both are lithium-iron-phosphate batteries, the cycle life is similar, up to 4,000 cycles.
Utility: When we look into the utility factors, lithium-ion batteries are suitable for the high-power requirement since they are maintenance-free and can last up to 4000 cycles.

Voltage: If the cells of the battery pack is the same, a 12v battery will have more Ah capacity than a 6v battery because 12v has more cells than a 6v battery. That means the usable energy will be more in a 12v battery than in a 6v battery. Ah stands for ampere-hour. Voltage is the electrical strength unit in electrical measurement.

Recharging: The charging time of a lithium-ion battery depends on the Amh and battery charger Ah. A 12v lithium battery at 6amps can fully charge within 8-10 hours. The charging time depends on the charger’s Ah capacity. If a charger can supply constant 1A, then to charge a 12v 6A battery, the charging time will be 6Ah/1A, which is equal to 6 hours for a full recharge. But lithium-ion battery charging is a bit complex. When the charge reaches 80%, the charging will slow down.

Because of this, the remaining 20% will take more time than what has mentioned in the theory. Up to 80% charge can reach within 5-6 hours, provided the charger can supply 1A current constantly.
Weight: A 12v battery will have more weight than a 6v battery. So, if you need to shift the battery from one location to another, a 6v battery will have the advantage.

Size and shape: A 12v battery will be rectangular and much bigger than a 6v battery. The size of 6v battery is 115mm x 68.2mm x 68.2mm and the size of 12v battery is 203.2mm x 228.6mm x 152.4mm H x L x W respectively. The average weight of a 6v and 12v battery is about 360gms, and 11-13.5kgs, respectively are the difference when comparing 6v vs 12v battery.

Price: The average cost for a 6v 100ah lithium battery is about $50-$100 per piece, and a 12v rechargeable 200ah lithium-ion battery is about $125-$180 per piece.

Can I charge a 6v battery with a 12v charger

You should not recharge a 6v battery with a 12v battery. It is risky and damages the battery. It would be best to use the correct voltage charger to charge a battery with a corresponding voltage. You have to use a 6-voltage charger to recharge a 6v battery.

Suppose you use a high or low-voltage charger to recharge a 6v battery; it will damage and overheat the battery and charger, leading to a risky situation, including a possible explosion. Many reports and industry experts reconfirm this report while comparing a 6v vs 12v battery.

Can I use a 6V battery instead of a 12v

Since a device circuit is designed to run on 12v, it will not run on 6v. So, you cannot use it. If you reduce the voltage, it will defunct some systems or won’t allow some sections to work.

How long does 6v vs 12v battery last for one charge

It depends on the amperage of the battery and ampere consumption of the device. When the ampere consumption is low, the charge may last for more hours. Apart from the amperage, power life may depend on the motor’s power usage.

Cycle life of lithium 6v vs 12v battery

Battery quality and material used for manufacturing the battery play a pivotal role in determining the life cycle of a lithium battery. It doesn’t matter the voltage of the battery. Generally, the lithium-ion battery cycle is about 1500-4000 times, and for a lithium-iron-phosphate battery is about 4000 times. These are relevant points when we make a 6v vs 12v battery comparison.

Technology advancement has contributed to increasing the lifespan of lithium-ion batteries. In a general perception, an average lithium battery can meet at least1500 life cycles (One charge and one discharge are equal to one cycle).

If you can maintain proper charging, you can get 4000 cycles for your lithium battery. Lithium batteries should not be subjected to overcharge and over-discharge for a better result.

Which is better, 6v vs 12v battery

This question, which is a better battery while evaluating a 6v vs 12v battery, needs to be addressed from a different perspective considering various factors. First of all, a 6v battery is 6 voltage battery, and a 12v is a 12-voltage battery. Both have their application based on the requirement. You cannot use a 6v battery in a device designed with a 12v power circuit and vice versa. Using a 12v battery on a 6v circuit device won’t work or get damaged.

Further, you must be sure about the ampere requirement of the device you want to run with the battery irrespective of its voltage power. If you use a low ampere battery instead of a high ampere requirement, your device won’t work.

Conclusion

Lithium-ion batteries are currently the most popular battery technology. We can always enjoy the battery performance of lithium-ion batteries because of the extended life and high ampere with a continuous power discharge. Lots of advantages are happening in this segment daily.

If you can use the battery intelligently by recharging the batteries in an acceptable temperature environment using the same amp charger, you can undoubtedly get more life cycles. So, comparing a 6v vs 12v battery is not enough to decide, but power usage, space, and convenience matter a lot when selecting the battery.
