So, how to charge 12v battery with 12v adapter? To charge a 12v battery with a 12v adapter, you will need to connect the adapter to the battery terminals. Make sure that the adapter is rated for the voltage of the battery, and that the battery is rated for the current output of the adapter.
A car battery needs a charge of 12 volts to start. The amount of charge that a battery can hold depends on the size of the battery and the number of cells. A typical car battery has six cells, each of which can hold a charge of 2 volts. So, a fully charged car battery will have a total charge of 12 volts.
There is a rumor unspoken rule : the slower charge the better battery, it seems charging current is around C/10 and
You can charge it with a 12V adapter. Just follow these simple steps: 1. Hook up the positive (red) lead from the adapter to the positive terminal on the battery. 2. Hook up the negative (black) lead from the adapter to the negative terminal on the battery. 3. Plug in the adapter to an outlet and turn it on. 4.
