You can find a wiring diagram for changing the input voltage of an Exide NPC12 3 680 L battery charger in the user manual that comes with the device, which is often available on the manufacturer's website. Additionally, check online forums or technical support resources dedicated to Exide products, as they may have specific guides or diagrams shared by other users. If you can't find the information online, contacting Exide customer support directly may also provide the necessary details.

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:Click on the image to enlarge it:Battery charger circuit diagramYou can see the values of the components used below:R1: 56 giga ohms resistorR2: 220 Mega ohms resistorC1: 105 Kilo pico farad , 250 voltage capacitorD1: IN 4007 DiodeD2: Light emitting diode indicatorD3 : IN 4007 DiodeIf 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.
You cant it comes with a charger
I think they mean "How do you charge a golf cart battery wired in series?" If you only have a 12 volt charger disconnect the batteries and charge individually. Wired in series you double the voltage, two 12 v batteries equal 24 v, three equals 36, four batteries equal 48v. Unless you have a charger that will charge the total voltage you have to charge each battery.
A twelve volt charger will charge twelve volt batteries only unless it has a feature that allows you to change the chargers voltage. But on fast or slow charge 12 volts is 12 volts so most 12 volt chargers are only good for 12 volt batteries.
Lift the seat up all the way and on the right hand side you will see the battery. You will need a battery charger with relatively small clamps. Pull the red plastic cover back from the hot terminal and connect the hot clamp from the battery charger. Then connect the ground clamp to the ground terminal on the battery. Be sure to set your battery charger on 12 volts
by changing the way the battery is positioned
Thanks for your contribution and thoughts but you CAN use a 4.2 volt charger for a 3 volt battery.JyotNo. You should not use a 4.2V charger for a 3V battery. The charger is specifically designed for the battery. Attempting to use a non rated configuration, unless the charger states clearly on its label that it can handle the 4.2V battery, could result in overcharge, overheat, even fire.Even attempting to place a resistor or zener diode in series with the battery is not a good idea, because some chargers use the voltage/time curve to sense when the battery is fully charged, and this will bias the results.
Try another charger that you know is working. If the battery charges - your original charger is faulty. If it still doesn't charge - the battery is faulty.
A lot of auto part stores will test them for free. Give them a call. Your alternator can only be tested when the engine is running, therefore you will have to get a boost or use a battery charger for the battery. If you have a voltmeter, test at the battery terminals with engine still running, if you get 13.5 to 14.7 volts, the alternator is charging. In some cars, the voltage could go over 15 volts if the battery is close to dead (right after being boosted), but the voltage should go back to normal as the battery gets closer to fully charged. Turn off the engine, the voltage will go down to 12.5 volts if the battery is now charged, lower if is not. If there is no change, the alternator is not charging. KGP484
It is saying that your battery or plug & play charger kit is low. Charge your adapter or change batteries.
