How many amps does a 12 volt battery charger draw? A medium amp output 12 volt charger would be in the range of 20 to 50 amps or so, and be used for many applications using about 100 amp hours of battery and up, or applications with a constant amp load (power supply application).
How much current does a battery charger draw? A basic charger usually charges at around 2 amps – and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market – from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.
How much watts does a 12V battery charger use? 30 A 12 V charger can charge a maximum of 360 Watts. This information is intended to be at the battery being charged side, since at the AC mains side you can consider from 20 to 40% more energy being consumed. The charger has losses in the conversion.
How many amps is a 12 volt trickle charger? The trickle charger produces a constant small amp charge, usually 2 amps or less, that keeps the battery fully charged while at rest.
How many amps does a 12 volt battery charger draw? – Related Questions
How to check ground wire with 12 volt circuit tester?
This is easy. Since you have already established a good positive source, attach one end of the circuit tester to the positive end. Now touch the other end of the tester to the ground wire for this component. If it lights up, you have a good ground and need to check the component further.

How many volts is ground wire?
You have to measure neutral-ground or hot-ground. If neutral-ground voltage is about 120 V and hot-ground is a few volts or less, then hot and neutral have been reversed. Under load conditions, there should be some neutral-ground voltage – 2 V or a little bit less is pretty typical.
How to link two 12 volt batteries?
To join batteries in parallel, use a jumper wire to connect both the positive terminals, and another jumper wire to connect both the negative terminals of both batteries to each other. Negative to negative and positive to positive. You CAN connect your load to ONE of the batteries, and it will drain both equally.
