Replace a battery with a power supply

Replacing a battery from a battery-operated equipment with a power supply can be tricky. Especially when the equipment uses an electric motor.

Run laptop off AC power without charging battery

Both of my laptops (HP Pavilion dv6z-3000 and Clevo P157SM) can run without a battery attached. To test whether this can be done safely, turn off the computer, remove the

power supply

This page has a good answer: "it depends". The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery

Does Lithium-ion battery behaves different than DC power supply?

Lithium batteries loose voltage as they are used. Your power supply doesn''t, but that shouldn''t affect operation. Be sure your supply is the correct voltage and can provide

How To Convert A Battery Operated Device To A Power Adapter

Laptops with Lithium-ion batteries have an extra circuit that cuts off the battery from power when it reaches 100%. You don''t destroy the battery by leaving it plugged in all the time under normal

Using a 9V battery instead of a DC power supply

How can I take a 9V battery plus a snap adapter and create a power supply that would be equivalent to the DC power adapter? Do I need to add a 6 Ohm resistor in the loop

6 FAQs about [Is it okay to change the lithium battery power supply to a direct plug power supply ]

How do you charge a lithium battery?

A fully charged Lithium is 4.2V. Just power it from 5V USB, with a standard 1n4001 diode in series to drop a volt. You might need an electrolytic capacitor across the battery place e.g. 1000uF to reduce noise and supply peaks. (batteries have a low impedance, and it has only 3" of wire) Brilliant! Why didn't I think about this?

Can You charge a lithium ion battery directly?

You can't wire a battery directly to the charger. Charging a Lithium-Ion battery requires a somewhat complex charging control circuit. Well, I shouldn't say you can't; you can, you just run a really high risk of blowing yourself up. Connectors are easy to replace. Which is broken?

How to charge a battery with a drooping power supply?

The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics (Far Left) where a constant current range is used for charging batteries with a constant current. The other two characteristics should not be used to charge batteries.

What is a switching power supply?

This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is a constant voltage power supply, so it monitors fluctuations in output voltages, inputs the results in the control circuit, and executes constant voltage controlling also known as feedback controlling.

Can a lithium ion battery be overcharged?

They added: Be sure to use lithium-ion and other such batteries with a battery management system (BMS*). When charging and discharging are repeatedly performed, differences in the charging capacity of the individual cells occur, and if discharging occurs in this condition, overcharging can occur.

Can you touch unprotected lithium based batteries?

When your batteries are quite empty too much current might flow and that will damage your batteries. A proper charging circuit is needed. See the list of related questions on the right --> and start reading. In my opinion no one should even be allowed to touch unprotected lithium based cells before understanding the basics of how to use them.
