Can I Charge A Lithium Battery With A Normal Charger?

Can I charge a lithium battery with a normal charger? People often ask that question when they can’t find the regular charger for the battery.

The answer is yes, you can use a normal charger to charge the lithium battery as long as it can provide the required voltage and current.

Now, it opens up a few more questions. Also, knowing the ratings of the lithium-ion battery charger tells us which normal chargers are suitable for the job. So, don’t skip any part and read till the end to know those facts.

What Kind of Charger Does A Lithium-Ion Battery Use?

The chargers that can provide a constant voltage and constant current are the right kind of devices for recharging lithium-ion batteries.

Remember that other battery chargers such as lead-acid ones have a different output characteristic.

They sometimes give pulses to the battery with high voltages for decalcification. And, you can’t do that with li batteries.

Can I Charge A Lithium-Ion Battery with A Normal Charger?

First of all, you have to define which ones you are considering as a normal charger.

In the introduction, I have given you a positive answer stating normal chargers can do the job. But that is the half-truth.

You have to understand that lithium cells are very sensitive requiring special charging circuits to manage them.

In most cases, it is not possible to get precise voltage and current from a normal charger.

For example, your li-ion battery recommends charging at 5V 1.2A, or a 6W charger is required.

Here, one must use a charger with those specific output power ratings.

Now, let’s talk about different types of battery chargers and their capabilities to charge a lithium cell.

Can I Charge A Lithium Battery with A Lead-Acid Charger?

Yes, you can do that but you have to have the ability to control the maximum voltage of the charger. And, the equalization mode must be disabled.

Can You Charge Lithium-Ion Batteries with A NiCad Charger?

According to the output characteristics of NiCad chargers, you can’t charge a Li battery with them without harming the cells.

But it is possible the other way around. I mean, you can charge a NiCad battery with a Li-ion battery charger.

What Is the Best Way to Charge A Lithium-Ion Battery?

There is a detailed guide on the best practice for charging li batteries. Let me tell you the process in short here.

First of all, you have to understand the nature of lithium cells. Otherwise, you won’t think twice before taking a risk.

One of the lightest metals on earth is lithium. Also, it is one of the highest reactive ones.

Because of energy density and the highest electrochemical potential, lithium is widely used in almost all electronic devices.

Even after using the right kind of charger, you will have to keep a few things in mind to prolong its service life and overall performance.

charge-current termination setting of a charger is also important to maintain the health of the cells.

Frequently Asked Questions(FAQs):

u003cstrongu003eWhat Is The Lithium-Ion Battery Charging Voltage?u003c/strongu003e

According to a study, most consumer-level Lithium batteries are charged at 4.2 volts per cell. And, the tolerance level of them is around ± 50 mV per cell.

u003cstrongu003eCan You Use A Regular Trickle Charger On A Lithium Battery?u003c/strongu003e

As lithium battery cells are very sensitive to overcharging, you can’t use a regular trickle charger on this type of battery. It will damage the cells in the process.

u003cstrongu003eDo Lithium Batteries Need A DC To DC Charger?u003c/strongu003e

For the sake of li-ion batteries’ health, you should use a DC-DC charger. It promotes the correct charging profile.

u003cstrongu003eCan You Charge A 36v Lithium Battery With A 12v Charger?u003c/strongu003e

Yes, one can charge a 36V li-ion battery using a 12V charger on one condition. He/she has to charge 12V cells separately or connect them in parallel.

u003cstrongu003e Is it OK to leave a lithium-ion battery on the charger overnight? u003c/strongu003e

With the advancement in the battery management circuit, it is now possible to leave the charger connected to your phone or laptop overnight without causing serious damage to the battery.


So, can I charge a lithium battery with a normal charger? I hope that you have understood the technical terms mentioned above.

The best way is to use a specific charger type for its respective battery type. There are multi-mode chargers capable of supporting different kinds of batteries.

Get one of those, and you will be able to maintain the health of the batteries.
