Finally bought a battery hydrometer, need help with results

That clears up a lot! A Megawatt and and an ammeter is the plan. Also, the actual batteries I will dry camp with will be the T-105's. All this messing around with wall warts and the Interstate 24 really is more about education than anything else. I have a really good grasp of electrical in general, both AC and DC. It's just when you get to batteries and charging in particular where there's a lot I still don't understand.
