PD9245 and Lifeline GPL-31XT testing
I just acquired a Progressive Dynamics PD9245 converter to specifically charge a New Lifeline AGM GPL-31Xt at 125AH capacity. I tested the converter tonight on a different battery, and saw Voltages...
Forum Discussion
Have a 9260 and the 100ah lifeline. My lifeline is 6 years old and still holds spec capacity.
I monitor AH discharge v/s battery voltage and it is still right on the money. I also let the Trimetric track total AH... Well over 5000 AH from this battery so far.
I do a c/20 discharge to 70% every couple of months. Measure the voltage, then recharge. This battery still is at spec capacity.
When the camper is sitting for a month or so on shore power I always reset my Trimetric Voltage high to insure that the PD9260 is doing its 14.4 every 23 or so hours. (does this for 15 min).
I do have 200 watts of solar which is inop when sitting at home in my covered port so it does not work.
During our trips I never plug into shore power... Solar takes care of it excellently.
Morningstar Sunsaver mppt... With temp compensation. During cold weather the controller will pump 14.9 for the battery and in the high 13's when 90+deg, love it!
I do like the ability to drop the charge voltage down to 13.6 when my Lifeline temperature is above 90 deg... and on shore power. I have not done that now for a few years because I have solar and let it do the temperature adjustments.
Lastly, after dealing with 2 gp24 FWC's for years and removing to check water etc I have not removed this lifeline since I put it in 6 years ago.... What a pleasure!
With the advent of led lights, led tv and the Wave 3 for heat we no longer need 2 batteries.
