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...

Hmmm ... where are you seeing that the GPL-30HT has a minimum charger rate of 20%?
For what it's worth, so far over the years I've not been able to find anywhere solid engineering statements stating that charging of a lead acid battery (AGM or wet) cannot be done slowly ... hence at low amperage rates. What I've found is that not charging them FULLY is the damage issue. RV batteries being exposed to low solar charging currents for hours upon hours still eventually fully charges them - just at relatively low current levels if one doesn't have a huge solar installation.
So far, I haven't been able to find the minimum 20% charging current requirement in either of these two Lifeline documents that apply to the their GPL-30HT battery:
- .pdf document for the GPL-30HT battery titled ... "manual.pdf"
- Word document for the GPL-30HT battery titled ... "GPL-30HT.doc"
