BLACK+DECKER Battery Charger FAQ

How to charge a lithium-ion battery without a charger?

If your charger is already dead and you need to keep the phone alive, there are several ways to try:

USB cable. Connected to a laptop, car charger, etc., the USB can also power your phone.
DC outlet. The regular power supply hooked by the relevant cables at the phone battery input can charge it. This method requires measuring equipment, constant attention and precise calculation of volts and amperes to come.
Power bank. The power banks can be of different construction and accumulate the energy from solar batteries or DC supply.
Solar-powered charger. However, it requires direct sunlight and a lot of hours to charge the battery.
Hand crank charger. This charger is completely independent on the electricity so that you need to power it by hand.

How does a battery charger work?

A lithium-ion framework is about the ions and electrons flow. They move from one electrode to another through the electrolyte, gaining or giving away the current. When charging is in process, the ions and electrode move from a positive electrode to the negative one.

The charger’s task is to activate this flow. This is performed on a simple constant current supply at the predetermined voltage. Once the battery voltage drops, it means it cannot take a charge anymore, and the feeding is seized. The chargers can feature different enhancements like temperature proof charging, fast safe charging, charge indication, automatic shut off, and so on.

How to test a battery charger?

No matter if you have the BLACK+DECKER battery charger or any other device, you should check its state on a regular basis. Having a voltmeter at hand, you can easily check your power appliance. Here’s a short action list:

1. Get the voltmeter ready. Install the test probes, ensure the power supply, select the “DC” measurement and put the indication slightly bigger than the nominal charger voltage.
2. Plug the charger into an outlet and connect the voltmeter to it. The red probe goes to the positive contact and the black to the negative one.
3. Check the voltage indication. An indicator on the left side means a non-working charger or incorrect probes placement. The indicator on the right side means the appliance is working. The reading will show how much charge it conveys. For sufficient feeding of the particular power bank, the voltage should be equal or higher than the cell’s indication.
