Don't think that they were Std. Equipment!
Paul:I do not believe that they were standard equipment. When you look around, you should get one that is a smart charger. I recommend that you look at Statpower if you are looking for a charger only. They make a 20 and 40 unit. If you want to upgrade beyond this you may want to look at an Inverter/Charger Combo. Heart Interface is a very good choice here. Be sure that if you go with an Inverter, that you get one that is big enough to handle the startup load for specific appliances that you may want to run (coffee pot, microwave, drills, motors, etc).You can find the Statpower and Heart Interface on the Xantrex web site.(http://www.xantrex.com/)
