What are 12v and 6v Lithium Batteries Made of?

6v and 12v batteries are pretty much identical in terms of their chemical makeup and structure. For a LiFePO4 lithium battery of any size, the chemical composition is simply lithium iron phosphate, a carbon anode, and a lithium salt electrolyte. Other types of lithium batteries will use the same chemicals, but they’ll also use lithium manganese oxide or cobalt in various amounts.

Those chemicals are used to make cells that range from 3.2v to 3.7v depending on the type of lithium battery, and those cells are connected in a series to reach the amount of voltage required for the battery being made. Those cells are then protected in a hardened housing to resist impact, electrical discharge, and other things that cause failures.

It’s important to note that the voltage rating is the voltage the battery can discharge continuously until it is depleted without fluctuation.

What’s the Physical Difference between 6v and 12v Batteries?

There isn’t really a chemical difference between the two, and the housings are largely the same designs depending on what each battery is made for. So, how does each battery physically differ, and how does that affect usage?

Well, it all comes down to the number of cells each battery has.

As we mentioned earlier, the higher the voltage you want, the more cells you need. Even the highest voltage cells only reach 3.7 volts in these batteries. So, making a battery that can discharge 6v of electricity continuously obviously requires half the number of cells as a battery that can discharge 12v.

This doesn’t mean that 12v is automatically the more powerful and superior option, though.

The way voltage works means that sometimes 6v is better than 12v due to how the battery operates with the ampere that a particular battery operates with.

Amp-Hour Capacity for 6v and 12v Batteries

The voltage is what you’ll usually see when buying a battery because it needs to remain consistent. However, amps and amp hours are just as important.

Amps refer to how much energy is flowing, and amp hours are how many amps can continuously stream in 1-hour until the battery depletes.

12v batteries are typically very flexible with their amp hours; with some models reaching 100ah or more. However, 6v batteries come in 5, 6.8, 10, and 12ah varieties. So, a 12-ah battery can discharge 12 amps of current at 6v for one hour before its cells deplete and need to be recharged.

Due to the primary uses for 6v batteries, that’s actually quite a bit of storage, and the max ampere isn’t often used. For example, if you’re using a flashlight with 5ah, it’s not going to discharge within just an hour. It’ll likely only use a couple of amps and last for hours on end. Keep this tidbit in mind throughout the following section.

How 6v and 12v Batteries Compare in Practical Usage

Despite being very similar, 6v and 12v batteries are typically used in very different applications.

In this section, we’re going to talk about the various areas each battery works best and why.

1: Diving Deep into 6V Lithium Batteries: Composition and Versatile Applications

In the universe of batteries, understanding the nitty-gritty of each type can make all the difference. The 6V lithium battery stands out in its unique composition and extensive applications. Here’s an in-depth look:

  • Backup Powerhouse for Household Gadgets: In those unexpected power outage moments, 6V batteries emerge as saviors, backing up devices like computers and TVs.
  • Adventurer’s Trusty Aid in Camping and Hiking: Those bitten by the adventure bug find a reliable ally in 6V batteries. Portable 6V lithium units effortlessly light up torches, headlights, or even run mini electronic tools during adventurous escapades.

6v is Most Commonly Used in Small Electronics

A 6v battery performs best when it’s delivering a steady, yet relatively low, ampere for long periods of time. This is why you’ll usually find them in smaller electronics that require a fair amount of power, but they’re not quite energy hogs like an EV car or anything like that.

These are commonly used for flashlights, toys, phones, tablets, and similar items.

However, there are some usages that are far more energy-intensive.

For example, some RVs use two 6v batteries in place of a single 12v battery, because they can get better ampere out of the duo than they would a 12v. However, they obviously have to stick two batteries side by side, and that ends up requiring more space. So, many still use 12v batteries for that purpose.

In most standard practical uses, 6v batteries are used for smaller electronics.

Final Thoughts:

The 6V lithium battery is more than just a power source; it’s a blend of innovative design and multifunctionality. Whether it’s a serene camping night or a demanding construction task, these batteries prove their mettle time and again.

2: What is a 12v Battery Used for?

12v batteries are more commonly used for electronic systems that need to maintain a consistent ampere and 12v voltage for long hours of constant use before resting to charge.

Most commonly, you’ll find them in recreational vehicles. The batteries that power golf carts, motocross bikes, and similar vehicles are typically 12v, and they’re hooked directly into the system just like a car battery. 12v batteries are also common in power tools that require high torque and higher ampere to generate that torque. So, items like power drills, impact wrenches, and similar electronic tools often have 12v batteries. Let’s explore the many avenues where these batteries reign supreme.

  • Energizing Electronic Vehicles: Primarily, 12V batteries find their stronghold in driving electronic vehicles, which includes an array that spans RVs, campers, wheelchairs, scooters, and even golf carts. Given the heightened energy demands of these vehicles, the 12V battery fits the bill perfectly. Boasting consistent power delivery, these batteries are adept at jumpstarting these vehicles with efficiency and speed.
  • The Backbone of Home Inverter Systems: For those seeking uninterrupted power at home, especially during unexpected outages, 12V batteries shine as the go-to option for inverter systems.

3: Weight Differences – 6v VS 12v Battery Solutions

There is another consideration that has to be made beyond just which one will provide steady ampere throughout the duration of your intended use, or which one can provide more power. Weight is a major concern in many applications.

6v batteries typically use fewer cells, and that dramatically lowers their weight in direct comparison to 12v batteries.

In some instances, such as driving a dune buggy or golf cart, the added weight of a 12v battery isn’t a concern, and it doesn’t impact the user or the vehicle.

However, weight is a concern when you’re talking about items such as flashlights, smaller electronics, battery-powered tools that don’t require much power to operate, and similar applications. The added weight can put more strain on the device, and it can make such items uncomfortable to use.

This is one major consideration when developing products for the consumer market, and it often plays a major role in designing the item’s power needs. Granted, 6v and 12v batteries can be made larger or smaller than the car-style batteries often pictured, but scaling them down affects capacity dramatically.

4: Why 12v is Almost Exclusively Used in Home Power Storage

If you’re looking at home power storage solutions, such as those used in conjunction with solar panels to help power a home during emergencies or cut back on electric bills, you’ll notice that almost every option you commonly see uses a 12v battery solution.

This is due to the high capacity and maximum 100ah rating that 12v batteries have. 6v simply doesn’t come close.

However, 48v batteries are starting to enter the home power storage space, and that provides another option for homeowners to consider when planning out their power needs.

Non-Use-Based Traits to Consider

There are a couple of things you should know about that change the performance of a battery without it coming down to the battery’s voltage.

1: Type

There are different types of lithium batteries. A 6v lithium battery can be a standard lithium-ion battery, one that uses manganese, or the newer LiFePro4 lithium batteries that provide unique benefits and drawbacks of their own.

The type of battery you get dramatically changes its performance.

2: Brand and Quality Matter

While the statistics we provided are standard, there are other specifications that vary dramatically. You can have two 6v, 5ah, batteries, and they’ll perform differently if they’re made by different battery suppliers. The build quality of the batteries, chemical quality, chemical ratio, and more can all vary from one manufacturer to another. That can create differences in lifespan, long-term performance, safety, and a variety of other things.

So, it’s best to try to get the best batteries you can regardless of whether you’re getting a 6v or 12v battery.

3: Ampere

When talking about batteries, voltage usually comes up, because that’s the potential electrical difference from the source to the receiving end of the current.

However, amps are just as important, and both 6v and 12v batteries come in varying amp ratings.

If you compare a low amp-hour 12v to a higher amp-hour 6v, the difference doesn’t seem so dramatic. However, when you compare a 100ah 12v to a 5ah 6v battery, the difference is so dramatic it’s like comparing an AA to a generator. The items that can be powered, and the duration of the battery’s discharge, are affected by that.
