12v Lithium Battery Charger: Voltage, Charging Method, and Need

Jul 13, 2020   Pageview:63

How many home appliances do you have? You might not have a lot, but we are sure that it’s not a little either. Some of them work by giving them energy, and the battery is one of the options to give them the said energy. A lithium battery is one of the batteries that can be used for the said energy, as it can be used repeatedly thanks to its rechargeable nature. Here, we will talk about 12v lithium battery charger and the things you need to know to charge the batteries properly.

How many voltages of lithium battery charger?

Before we start with the charging process, it’s best for us to understand what a lithium battery is

What is a lithium battery?

Lithium batteries are basically batteries made out of lithium. The most basic lithium batteries are commonly used for household appliances. They are also the batteries that can be found in minimarkets too.

Later on, an upgrade of lithium batteries is found, and they are called lithium ion batteries. Lithium ion is similar to its predecessors, except that it has different chemicals and other perks that cannot be gotten from its predecessor.

The first perk lithium-ion has is the amount of energy it has. It can contain up to 3,500 mAh at most, so don’t be surprised if you see some lithium ion batteries having energy around 3,000 to 3,500 mAh.

Besides its large amount of battery, lithium ion batteries also have large discharge power that gives consistent power throughout the battery usage. So, you don’t need to worry about having your device stops moving for no reason; the device will remain consistent and normal until the battery’s energy is finished.

Lithium ion batteries charger and voltage

When the battery is finished, what should you do? You recharge it, of course! As it has been stated, lithium-ion batteries can be charged when its energy is finished. So, there is no need for you to buy batteries when it’s done. You only need to spend more money on the charger, and that’s it!

There are many kinds of battery chargers for lithium ion batteries, both online or at physical stores. So, there is no need for you to get confused as to where to get the chargers!

To be able to charge the batteries properly, you will need to know the number of volts you need to charge it properly.

There are different volts you can use, but to play it safe, it is best to use 12 volts when you charge the lithium-ion batteries. When you use 12 volts during charging, there’s no need for you to worry that the battery will be overcharged. It is thanks to the constant voltage of the charger. Moreover, when you the battery finishes charging, it will stop right away.

So you can always leave the battery peacefully without having to worry that it will get overcharged. In fact, you can also leave the battery overnight too! Let the battery takes care of itself.

Can you charge a lithium battery with a normal charger?

There are moments where some people do not have lithium-ion chargers and only have normal chargers, such as the lead-acid charger. Can such charger be used?

The answer is yes, you can! However, there are some requirements you need to do when you charge the lithium-ion batteries with lead-acid charger.

The first requirement is the voltage. Just like how it is with lithium ion chargers, you need to have at least 12 volts to charge lithium ion batteries using lead-acid chargers.

You must never, however, set the voltage above 14.6. You must also make sure that the charging can be turned off right away because it needs to be turned off manually as soon as it has done charging. This is why you must not purchase a lead-acid charger with the equalisation mode either, as the mode prevents you from disabling/turning off the charger.

Aso, you must not use the charger to store the battery. You must not connect the charger to the electricity all the time either. After all, there is no such thing as constant voltage when it comes to battery charging.

It can eventually lead to damage, and the damage to the battery can be severe. It is the kind of damage that cannot be covered by battery warranty, so it’s best not to do such a thing. Of course, the ultimate solution is to purchase a charger specifically for lithium ion batteries.

How do you charge a lithium battery without a charger?

If you don’t have a charger, some battery cells and metal wires will do the trick for you. All you need to do is to connect the batteries, and then attach the wires to the batteries. Then, you connect the battery-turned-charger to the battery you want to charge in serie. It means that you must connect the negative side of the charger to the negative side of the battery, and the same goes to the positive side. After that, you only need to wait until the battery is charged. However, it should be noted that you won’t get full energy for the battery. But hey, it’s better than nothing!

Another trick you can do is rubbing the battery for several minutes. It actually doesn’t give energy, but it reignites the last moment when the battery almost on the verge of death. It’s not the most useful trick, but it’s definitely useful for those who need to do something urgently.

Charging lithium-ion batteries are not not complex, but it’s no simple matter either. You cannot charge just like that, as you need to know the volt and things related to the charging process. If you don’t know them, there is no way you will be able to charge the lithium ion batteries properly. And if you’re persistent, you might even damage the battery, making it unusable. Rather than having such a thing, it’s best to understand the process first, then charges the battery properly.
