How Do I Choose the Best 12V Battery?

Can you imagine how life would be without batteries? There are numerous variations of them, such as 3.7V batteries, 9V batteries, AA batteries, AAA batteries, you name it, and all of them have their practical uses in our modern world. You are probably reading this article from your laptop or tablet, which is, obviously, powered by a rechargeable battery. Even electric cars use batteries (and a great deal of them) to move you from point A to point B, so the importance of such accessories cannot be stressed enough.

One of the most popular types of battery is the 12V battery, which is usually used for remotes, flashlights, even to jump start your car. They are more powerful than other types of batteries and come at very low prices, so buying in bulk seems the right thing to do. We have analyzed the market extensively and found out more about these batteries to help you pick the ones you need. Keep reading this guide to find out everything you need to know about 12V batteries.
We are quite sure this is not the first time you are buying batteries, and you know that they are quite affordable, however, it is also important to know how many units you are getting in the package, and what can you do with your 12V battery. For example, you can buy 12V batteries between about $5 for a pack of four, and $25-$30 for a single rechargeable 12V battery that can be used for powering alarm systems or UPS systems. In some cases, batteries that can jump start your car and even recharge your phone can cost around $300.

Obviously, you need to know very well what types of batteries you require for your devices, and then set the budget. Be advised that there are also many cheap 12V batteries, usually costing less than a fiver for a pack of eight, but these products should be avoided, as they are not reliable.
Let's go ahead and find out more about 12V batteries, as they are available in several different types and can have various characteristics.
  • Type - Some batteries are rechargeable, others are not, so if you are using certain gadgets extensively such as a flashlight, you might want to spend a little more and go for a rechargeable model.
  • Uses - In most cases, small 12V batteries are used to power remotes and kids' toys, while larger ones can be used for UPS systems and home alarms. The latter usually have higher amperage, and that’s why they are suitable for electronics which require more power.
  • Quantity - Some manufacturers sell packs of two, four, six, eight, or up to 24 batteries per pack, so you should know what you are getting for your money.
In some cases, certain batteries are specially designed to perform other tasks, not just powering your devices. For example, some of them incorporate voltmeters and can be used to power your smartphone. Others might have a built-in flashlight, which is useful in various situations. At the end of the day, the most important numbers are the voltage of the battery (12 in our case) and the amperage, which is usually stated as Ah (Ampers per hour) or just Amps. The higher the amperage, the more powerful the battery is, and you can use it to power up multiple electronics, maybe even your vehicle.
Construction and Design
Most 12V batteries are built using lead acid, and that’s why you shouldn’t open them or let small kids play with them, as this substance is rather dangerous. They usually come with F1 terminals, which allow you to connect them to a wide variety of devices, including computers, motherboards, electric scooters, lawn mowers and many others.

If you want 12V batteries with a higher amperage, you should expect them to be a little bulkier, probably around two to three pounds, because they contain more acid to produce more power. However, they remain portable and easy to carry around, so if you go camping a lot, you can leave one in your RV to be used for emergencies. 12V batteries are not particularly striking to look at, and they cannot be used for decorative purposes, so there isn’t much information you need to know about their construction and design. We are also sure you don’t want a complex physics lesson on how they work, as that can be quite boring for some, so as long as you know what you are going to use them for, you'll be fine.
Performance and Ease of Use
Before wrapping it up, we want to mention a word about safety to ensure you have more peace of mind. Lead acid batteries have been seriously upgraded in the last years, and today they are spill proof and rigorously sealed to prevent accidents, overheating, and so on. As long as you keep them away from heat sources, you should be able to use your 12V battery for a long period of time. Also, make sure you check out the warranty information, as some batteries, particularly those with higher amperage, are backed by warranty periods of one or two years.
