also if i remember correctly that charger is only capable of 2A charge rates, and may not even be able to supply that on the transformer that it comes with. I think that it is able to supply 2A on both sides if you run it off a car battery due to higher input capacity to the charger than the AC transformer is able to supply.
This is correct. It will only supply 2.00 amps total on the DC power supply. So if you are charging two batteries it is only capable of charging each a 1.00 amp.
