Rogue MPPT, 490W and charging mysteries
Now that we were finally all in one place - me, Rogue 3048 and my rig - it was time to have some fun. 1)Battery: old starter, tested beyond dead, plates above the water. No wonder, 8 months in Mex...

Almot;
1. What is the age, based on the mfgr date, of the batteries that were stored for 8 mos?
1a. Were the batteries at full charge before the 8mos storage?
1b. What was the temp during storage?
1c. What were the Volts after 8mos?
1d. How did you arrive at 75% SOC?
2. Would you describe their current usage to date as standby or cyclical?
2a. Standby: what is the charge rate at 13.62V? (2.27V/cell)
2b. Cyclical: what is the charge rate at 14.4V? (2.4V/cell)
3. Would you describe your current charging as conditioning or regular charging?
FWIW, I have never conditioned/recovered my three AGMs.

1) Bought from Arizona Windsun in Jan 2013, they are a decent store. Darn Chinese forgot to stamp the date. There is a sticker with all the months and numbers from 0 to 9 (year?), but none of the boxes is checked. There is also an engraved number 1220JH which "might" be December 20.
1a)No. Did not have Rogue when brought the batts to this neck of woods. Before 8 months the Voc was 12.7.
1b) 50-110F
1c) 12.45
1d) Voc=12.45
2) No usage until now. What I wrote about was the very 1st charging and 50% discharge test wit 8A bulb.
3) Charging and load test of one battery mentioned yesterday. After that, today re-charged 2 other AGM to Float and the one that was 50% tested (not finished ABS on the latter, short day) - more in a separate post.
