TYPES OF BATTERY CHARGERS
There are three main kinds of battery chargers. These are identified and explained in details hereunder:
These chargers use the pulse technology to power up phones. The pulse technology entails the use of a series of current or voltage pulses to feed the batteries. These pulses are controlled in such a manner as to set the rise pulse repetition rates, pulse width, amplitude, and rise times.
Smart chargers have the ability to detect and respond appropriately to the conditions of the batteries. They can also vary the various charging actions accordingly.
A simple charger is a charger that possesses the bare minimum features, parts, and components of the typical charger. They supply constant or pulsed DC power to the batteries that are being charged. It does not, however, vary the output on the basis of the charging times or quantity of charge on the battery.
A CHARGING GUIDE FOR BATTERIES: HOW TO CHARGE YOUR BATTERIES
Insert the Battery in the Charger
Start off by inserting the batteries into the charger. Be gentle while doing this to prevent any damages to the battery. Take care of the polarities as well to prevent the distortions of the chemical states of the batteries.
Plug the Charger on the Socket
Proceed to plug the charger on the socket. After you have inserted the plug in the socket, do not switch on the charger, at least for the time being.
Set the Necessary Parameters appropriately
Set the necessary parameters appropriately. These include the charge duration, top temperatures, voltage, and current, among others.
Switch on the Charger
Now switch on the charger. Wait for the charging process to conclude before switching it off. Some chargers are automatic and so do not require physical attention.
Switch off the Charger
At the conclusion of the charging process, switch off the charger and unplug it from the socket. You do not want to experience damages to the charger, do you?
SAFETY GUIDES FOR CHARGING A BATTERY
Keep the Charger at the Right Temperature
Chargers are very sensitive to temperature levels. Too high temperatures can interfere with their functioning and also overwhelm the batteries. While stored, keep the ambient temperatures cool enough to prevent damages and malfunctions.
Put the Charger out of reach of Children
Children are very restless and lack restraints. The last thing you would want to do is to subject them to the risks of electric shocks and other hazards. This is why you must keep the chargers as far away from them as possible.
Store the Chargers Securely while not in Use
While in store, be sure to lock the cabinets and the other compartments wherein the chargers are stored. This is to prevent unauthorized access and with it, the attendant injuries.
Use the Chargers Moderately
It goes without saying that the more frequent you use the chargers, the more likely they are to wear out sooner. To be guaranteed of being able to use them for longer, you have to do so moderately. Use them if and only if you have to.
Pay Constant Attention to the Charger while in Use
Even though most modern chargers are automatic, you still have to monitor them constantly throughout the charging process. You just never know when a disaster might strike!
