Ni-Cd , Ni-HM and other rechargeable batteries are in massive use now a days.
Let me not describe the use , importance and bla bla of the rechargeable batteries.
What we are going to talk about here is how to make simple battery charger circuit to recharge your rechargeable batteries.
Making a battery charger circuit is very simple , Simply step down the mains voltage using a step down transformer and convert the current into DC and stabilize it using a bridge rectifier circuit.
But you might not want to use a transformer in your circuit to maker your battery charger circuit small and handy.
If you don't want to use a a transformer to step down the mains voltage then you can also use a resistor and a capacitor to step down the voltage and stabilize it.
And you can see the circuit diagram of a battery charger below which is not using any transformer. Battery charger circuit diagram:So here is a simple battery charger circuit diagram:

Battery charger circuit diagram
You can see the values of the components used below:
R1: 56 giga ohms resistor
R2: 220 Mega ohms resistor
C1: 105 Kilo pico farad , 250 voltage capacitor
D1: IN 4007 Diode
D2: Light emitting diode indicator
D3 : IN 4007 Diode
If you use the values of the components stated above the circuit can recharge a 3 voltage rechargeable battery , You can change the value of R1 and C1 to get recharge battery of more voltage.
What else can I help you with?
Can a Diode be used on a battery charger?
ya. we are using diode in a battery charger to convert ac into dc. 230v dc is step down by using step down transformer
How can a capacitor be charged using a battery charger?
To charge a capacitor using a battery charger, you connect the positive terminal of the battery charger to the positive terminal of the capacitor, and the negative terminal of the battery charger to the negative terminal of the capacitor. The battery charger will then supply a voltage to the capacitor, causing it to store electrical energy.
What is the best way to charge an LP-E10 battery using a battery charger?
To charge an LP-E10 battery using a battery charger, follow these steps: Insert the battery into the charger correctly, ensuring the contacts align. Plug the charger into a power source. Wait for the battery to fully charge, indicated by a light or display on the charger. Once charged, remove the battery from the charger. Avoid overcharging to prolong battery life.
How long do you need to charge your car battery using an automatic battery charger?
If it is an automatic charger let it charge until the charger shuts off.
Can you charge a gas scooter battery using a car charger?
As long as it is a 12 volt battery you can if you set the charger on low.
How do you charge a battery using a battery eliminator?
You do not charge a battery using a battery eliminator. The eliminator is not a charger, it is an eliminator that allows you to run the device.
How can i charge my car battery from home using a laptop charger?
Sorry, but that is not likely to work. Both the voltage and amperage provided by a charger for a laptop battery will not be correct for a car battery. It is likely that you will damage the charger.
Does the type of charger you use matter for having a good battery life?
Yes, the type of charger affects the battery life of your device; using a charger not recommended by your manufacturer ruins the battery life of your device.
Can you use a 120V Dewalt battery charger rated 120V 60Hz off of a step down transformer putting out 120V 50Hz?
It will charge the battery a few times, but eventually it will ruin the battery. The problem is the difference in the Hz. The charger is designed to convert power at a specific level to DC power. When the input power is not at the needed pulse rate, in this case 60 Hz, it will not emit the correct DC voltage and slowly reduce the batteries capacity to hold a charge. If you want to continue using the 60 Hz charger, you need to convert the 50 Hz power into 60 Hz by filtering it through a battery. Example: Step down transformer 50 Hz 120v --> Battery supply (Uninterruptable Power Supply that can handle 50 ~ 60 Hz) --> Dewalt 60 Hz battery charger.... Or you can skip the science project and buy a 50Hz Dewalt battery charger. You may need a plug converter depending on the type of outlet you are using and the plug type the charger will come with.
LG Phoenix 2 wont turn on?
Either the battery is not retaining its charge - OR - the charger isn't charging the battery. Either way try using another battery - or charger.
Will a wall charger mess up my Ipod or its battery?
i have been using a wall charger for about 1.5 years, and my ipod and its battery still work fine
Can you charge a 28 volt Gill aircraft battery with a 12 volt car charger?
No, you cannot charge a 28 volt aircraft battery with a 12 volt car charger. The charger voltage needs to match the battery voltage for safe and effective charging. Using a charger with a lower voltage can damage the battery and pose safety risks.
