MW & LY - Thanks agin for the thoughts and info sharing.
MW - You understand my puzzlement completely. I felt 8 years would have been quite realistic, and long range retirement budget planning had amortized purchase price over 8 years (Though I of course hoped for more.).
I've seem the Meanwell mentioned a few times now. It is a dedicated charger to do nothing but charging - and has great feedback at doing that very well. Sort of a Swiss Army Knife dedicated charger.
LY - I'm really trying to be as open as I can about how I've cared for the bank. Again they were bought in January of 2013, (Drove up and picked them up from the older Azusa warehouse, to assure fresh stock.). The first 5-6 months, they were supported by the OEM Freedom 458. Set to the AGM setting, which is not really ideal for Lifeline. (But again, talking to Lifeline this bank was for then medium to large size, and they saw no problem with me using this as I mapped out my move to PSW and Solar with a Controller.).
I mention this, because it was 6 or so months with less then ideal Lifeline settings.
I'll again share, that in the life of the batteries, I've had it in the shop two times for a two week visit and three week visit. (The three week, was when the solar and Magnum swap out was occurring.) Yes, they assured me they would keep it plugged in. They also said that the two-three days of the Freedom swap over to MS2812 - that they would first make sure the bank was fully charged. BUT - I have no way of known those two times the bank was properly supported.
The Solar Controller and the MS2812 I feel were set up to play nicely with each other. One area I'll review to see if I messed up. And, many times while on shore power, I turn the MidNite Controller to avoid conflict.
I also three years ago upgraded the Alternator form 160 to 200A - but also added regulators to manage that. (Perhaps a problem on that end, yep, will retrace what I asked to be done, and see what was really done:)!).
Batteries resting now, and will get voltage readings in the to confirm what is what.
Yeah, out of the prorated warranty now. And I would not doubt Lifeline would ask reasonable questions about care. Willing to talk with them about that, as mentioned, I want their confirmation that they feel I've done the right maintenance.
One step at a time:)!
