Once the cover is off, locate the black and red wires coming from the AC input. Thanks, Paulo, from Brazil. But sometimes we cannot buy them. The rectifiers job is to convert the AC power from the transformer into DC power. The electrolyte and the load together determine the voltage of the battery. The rectifier should be able to handle the amount of current your power source produces. Once the battery is on, switch on the headlights to "load" the battery and reduce any surface charge that the battery may have built up. Connecting the Amperimeter to the output will burst the XL4015E1 IC or Multimeter. You can use this charger to charge any 12V lead acid battery, including car batteries. 4. That means if the battery is 12V, the transformer should be 24V, and if the AH of the battery is 7.5 then dividing this by 10 gives 750mA which becomes the recommended charging rate of the battery, multiplying this by 2 gives 1.5Amps, so this becomes the required current rating of the transformer. A 12-volt battery charger is an essential tool for any driver. So, what does this all mean for you? The advantage of this approach is that it eliminates wasted heat in the form of heat dissipation in resistors; efficiency can thus be increased to as much as 85%. Without a transformer, you can charge it urgently. I have also used this charger as a power supply for things like a hot wire cutter. Checking model numbers, one has ZK-DP60 another is ZK-J5X V2. The rectifier will convert the AC current from the power source into DC current. To make a charger without a transformer, you will need a rectifier, some wire, and a power source.
