David Jones has another useful video tutorial about how to safely charge Lithium Ion and Lithium Polymer batteries with a bench power supply. The purpose of this tutorial is to learn how to use your lab power supply to charge your Lithium Ion battery when you don’t have a special charger circuit to do so.
The purpose of this tutorial is to learn how to use your lab power supply to charge your Lithium Ion battery when you don’t have a special charger circuit to do so. He used NCR18650B in his tutorial, a 3.6V 3400mAh Lithium Ion battery from Panasonic.
You can also use the power supply to equalize a lead acid battery by setting the charge voltage 10 percent higher than recommended. The time in overcharge is critical and must be carefully observed. (See BU-404: What is Equalizing Charge) A power supply can also reverse sulfation.
Storing lithium-ion batteries at full charge for an extended period can increase stress and decrease capacity. It’s recommended to store lithium-ion batteries at a 40-50% charge level. Research indicates that storing a battery at a 40% charge reduces the loss of capacity and the rate of aging.
However, this is only partially true. The lithium-ion battery’s voltage increases as it charges, but the relationship is not linear. It can vary based on several factors, including the battery’s age and temperature. For instance, a typical lithium-ion cell might show a voltage of 3.7V at 50% charge.
Data shows that partial charges can be more beneficial. According to Battery University, lithium-ion batteries do not require a complete charge cycle, and partial discharges with frequent recharges are preferable. Full eruptions should be avoided because they put additional strain on the battery.

Can I charge a car battery with a 14V power supply? 14V is good; most automobile batteries are charged at 14.4V. Can I charge a car battery using a 13.8 V power supply? Your power supply can charge your automobile …
Lithium-ion batteries should be charged in environments with temperatures between 0°C and 45°C. Charging in extreme conditions—above 60°C or below -20°C—can damage the battery …
Generally, the most ideal value is 0.8 C, but even a lower value can extend the life of the battery. If you can, it''s better that you don''t use fast charging. Temperature should be monitored while charging Li-ion battery i.e. for optimum battery charging, it must not be charged at a temperature lower than 0°C or higher than 45°C.
Lithium-ion charges similarly to lead acid and you can also use the power supply but exercise extra caution. Check the full charge voltage, which is commonly 4.20V/cell, and set the threshold accordingly. Make certain that none of the …
If you have access to a DC power supply with adjustable voltage output, you can use it to charge your 20V lithium battery. This method allows you to control the voltage applied to the battery, ensuring safe and efficient charging. Follow these steps:
No, an adjustable constant voltage supply can''t be used to charge batteries, because a power supply is not a charger. A power supply like the LRS-350-24 tries to keep the output supply voltage constant. For example you can set it to 26V. A somewhat empty LiFePo4 could have 22V.
Can you charge a lithium ion battery with a power supply? Lithium ion batteries can be charged manually using a power supply. However, when using a power supply for …

Granted this is not a charger yet, it still needs a regulator or two to be able to control the voltage and current to make it a proper battery charger, but this is the core of the battery charger as it is the input power supply. Even though this is a fixed-mode power supply and it''s not listed on the page, there is an adjustment screw on the ...
Can you charge a lithium ion battery with a power supply? Lithium ion batteries can be charged manually using a power supply. However, when using a power supply for charging a Lithium ion battery, voltage and current limiting are adjustable. Moreover, the charging process can never be left unattended, charge termination is not an ...
This tutorial applies to all Lithium Ion and Lithium Polymer batteries not only NCR18650B. You can perform this 2-stage charging using your power supply, but it must …

Let your phone lithium-ion battery charge while you''re sitting still—but don''t overdo it. Tamarcus Brown/Unsplash . Share. This story has been updated. It was originally published on 8/23/17 ...
A lithium battery charger is just a fixed voltage power supply with current limit. Sure - you can set the voltage wrong but if you know what you are doing and are careful, you …
Key Takeaways: • The lithium battery is rechargeable, and lithium ions can migrate from the negative to the positive electrode. • Lithium batteries facilitate the transfer of lithium ions between the anode and cathode via the electrolyte in conjunction with the movement of electrons in the external circuit. • There are seven ways to charge a lithium battery: USB …
Lithium-Ion Batteries: Typically, set the voltage to around 4.2V per cell for safe charging. Next, set the current limit according to the battery''s specifications. A good rule of …
Lithium-ion charges similarly to lead acid and you can also use the power supply but exercise extra caution. Check the full charge voltage, which is commonly 4.20V/cell, and set the threshold accordingly. Make certain that none of the cells connected in series exceeds this voltage. (The protection circuit in a commercial pack does this.)

This tutorial applies to all Lithium Ion and Lithium Polymer batteries not only NCR18650B. You can perform this 2-stage charging using your power supply, but it must supports CC(Constant Current) and CV(Constant Voltage) modes.
Lithium-ion batteries should be charged in environments with temperatures between 0°C and 45°C. Charging in extreme conditions—above 60°C or below -20°C—can damage the battery or reduce its lifespan.
IMO you can use a good power supply in a pinch as long as you do it right and you have a BMS in the battery that monitors the individual cell voltages. A Lithium charger is just a current limited power supply that is set to the correct open circuit voltage and correct short circuit current. I have built several of them.
The full charge open-circuit voltage (OCV) of a 12V SLA battery is nominally 13.1 and the full charge OCV of a 12V lithium battery is around 13.6. A battery will only sustain damage if the charging voltage applied is significantly higher than the full charge voltage of the battery.
Generally, the most ideal value is 0.8 C, but even a lower value can extend the life of the battery. If you can, it''s better that you don''t use fast charging. Temperature should be monitored while charging Li-ion battery i.e. …
