Place your charger where you can get to it easily to plug it in.

The other question is. The charger has only a red and a black wire coming from the charger. The left and right batteries are 12 volt each.

If all you have is the 1 charger you would have to disconnect the jumper wire between the 2 batteries and charge them seperatly 1 at a time.

So you hook up the Battery Tender first to the left side battery at 12 volts and then after that charge -hook it up to the right side battery at 12 volts.
