Renogy Charger Settings for Trojan T-105
When I first got my Renogy Portable Solar Suitcase, I had a single 12v battery and just hooked it up. Then I started reading the manual and found that the charger had a default battery type of AGM. A...

I don't have a problem with your concerns because I don't know enough to know if the numbers are good or not. I will update once I get a consensus from Renogy and Trojan. However, this is from the Trojan site:
FOR SOLAR APPLICATION
Store and operate your batteries in a cool, dry place.
For every 18° F (10° C) rise above room temperature (77° F or 25° C), battery life decreases by 50%.
Charge your batteries fully after each period of use.
Allowing your batteries to sit in a low state of charge for extended periods will decrease their capacity and life.
If you store your batteries for an extended period of time, be sure to charge them fully every 3 to 6 months. Lead acid batteries will self-discharge 5% to 15% per month, depending on the temperature of the storage conditions.
Monitor battery voltage and specific gravity of the electrolyte regularly to verify full recharging. As a general rule of thumb, the total amps from your PV panels should be sized between 10% and 20% of the total amp-hours (Ah) of the battery pack.
Many charge controllers have equalization settings that you can set to help ensure the health of your batteries. Equalize your batteries at least once per month for 2 to 4 hours, longer if your batteries have been consistently undercharged.

Volt Settings 12V
Daily Charge 14.8
Float Charge 13.2
