12 volt 7 amp Battery (Features, Benefits and Uses)

We live in a world full of batteries. The most commonly used battery out of them is probably a 12v battery but even this battery has its further types. A 12 volt 7 amp battery is one of such types which is used more often.

We have a full length article on a 12v rechargeable battery in our Blog section. However, there was a need to guide about a 12 volt battery with the 7 amp current which slightly acts in a different way.

As we know that we are all surrounded by the batteries and maybe we cannot survive efficiently without the power storage devices like batteries, we must be aware of their possible uses. They are used in almost everything. Batteries make things easier and convenient. Many things can be operated on the go just because of batteries.

Batteries are useful because they are portable, they keep your devices functional even when you are not near an electricity socket. This article specifically portrays the features and the benefits of a battery having a 12 volt and a 7 amp capacity.

Features and benefits of 12 volt 7 amp battery

We have covered the sparkling features of such batteries in this section which include the following:

Special Lead Alloy with Low Calcium

Better Durability

Resin or similar material battery cases

Shock Protection

Unique Material Components

Enhanced Performance

Optimized electrolyte reactions

Reduced leakages and spillover effects

Working of a Lead Acid Battery

A 12 volt 7-amp battery is usually a Lead Acid battery. They are made up of plates of lead. They consist of lead and lead oxide. The battery works on these plates and the electrolyte.

The electrolyte is made of two things. It is it mixture of two liquids. It is made of 35% sulfuric acid and the rest is water. This solution is called the electrolyte. The working of the battery is based up on the electrolyte and the lead plates.

When the battery is being used, the sulfur ions move to the plates to conduct electrons. This produces electricity that is then used in the appliances. When the battery is running low on electricity, it means that it has low quantity of sulfur in the electrolyte.

Sulfur that was present earlier, is now on the plates of the battery. When you recharge the battery, you make the sulfur ions go back into making the electrolyte by mixing back with water. To run a battery in a good way, you must make sure that it has the right quantity of water and sulfuric acid in it.

Battery Maintenance

Maintaining a 12 volt 7-amp battery is one of the most important things. Many people ruin their battery’s life by not maintain it or dealing it with a way that is not supposed to happen. When you have a lead battery, make sure that you check the water content regularly, especially in hot weathers.

You should always make sure that the battery is recharged right after it loses its energy. If it does not get recharged, it might lose its energy.

There are certain things that you must avoid when dealing with a lead battery. You should never change the electrolyte of the battery, you should always make sure that the battery doesn’t die, or simply doesn’t get discharged to the end. You should also avoid adding tap water into the battery.

Tap water is not right since it has harmful contents for the battery. You should never use other batteries that are unregulated, to charge the battery. You might end up damaging both of the batteries. If you observer the battery to be hot, or the electrolyte to be boiling, this might be an indication that the battery is in a very bad condition.

Now we come to the most important part, which covers the uses of 12 volt 7 amp battery. Below are mentioned some of the fields that have a lot of battery usage.

Uses of 12v 7 amp Batteries


Most of the batteries are used in your own house. There are many things that run-on batteries. You have your remotes, weight scales, flash lights and many other stuffs. Many things on the house run on batteries.

Your mobile phones have batteries. Mostly the advanced batteries that are used around the house are in the laptops or the mobile phones. They are lithium batteries instead of the nickel ones. Since, lithium batteries can give out much more power as compared to the nickel batteries.


Batteries are more important in the military than we consider them to be. Some of the most important things are being run on batteries. The soldiers have intercoms and radios that they use to stay in contact with the headquarters and the other soldiers. These things always require a battery.

Battery is one of the most important things that are in the backpack of an armed officer. They have other things that run-on batteries. For example, when carrying out tasks in the night, they have night vision. A night vision always requires a set of batteries.


Batteries are also an important part of the construction industry. There are many things that they use, that run-on batteries. There are many things that have batteries of different kinds. There might be regular batteries or heavy duty batteries.

They use batteries in things like forklifts. When they are working in a congested area, there is a risk of using an engine because it would pollute the air, that would make things dangerous for the people. So, they use batteries instead. Batteries are also used in the larger machines. They are heavy duty batteries. They tend to power the electronics of the machines.


Batteries are a big part of the hospitals and the medical environments. There are many things that run-on batteries there. Things like defibrillators or pacemakers. They require their equipment to be mobile.

Because when there is an emergency, they can’t just take the patient here and there. They need their equipment to be near them when they are operating on the patient. That is why batteries are important in Hospitals. The batteries that are used there are usually rechargeable. They are the most popular batteries that are used in the medical field.


 Another use of batteries is in the toys of children. There are many sorts of batteries that are used in the toys. But mostly, the batteries that are used, are not heavy duty. They most used batteries are AA size batteries and smaller ones.

But there are other toys that might require other sizes of batteries. Like power wheels, power wheels require a 12 volt 7 amp battery. These help the power wheels run at a moderate power, and children enjoy them too.

There are many other uses of batteries. In modern cars, the engine is replaced by batteries. We never know what will happen in the days to come.


​A 12 Volt 7 amp battery is the requirement of the most of electrical equipment. You need to be careful in choosing the right battery in order to have the ideal performance of the batteries you have. A nominal voltage and the right amp are specified by the OEMs and if you deviate from those specifications, you might lose your equipment’s performance.
