Trailer Battery Load Support
As a followup to my recent discussion about my newly acquired CTEK Multi US 7002 Charger I'd be interested in some further input on the subject of trailer battery load support. :) First, I should c...

Hi BFL13;
Nice to see you back.
Your test doesn't include any times so I assume you were only testing for initial Volts drop. That is good info and I am not suggesting you should proceed with a capacity test.
I got the two 5yo(as I was told) 135AH telco pulls last year. At rest they read 12.88V @ 85F. I wanted to establish a baseline capacity to know what to expect from them.
Before installing them I ran 1.00KWh from them in parallel by using the Magnum 1000W/50A inverter/charger with 6 feet of 2/0 cables. I used a KAW to observe that the 800W ceramic heater ran 1:15 to use 1.00KWh. At that point, the batteries were reading 11.99V on the Turnigy. After a :15 rest, the Turnigy read 12.33V. I did not measure Amps or AHs.
