Well I thought I'd do a hydrometer test. The battery of the left had good readings on 5 cells (all the beads floated) but had 1 cell bad. On the battery to right, no beads floated at all. That tells me that battery is no good. Looks like time for 2 new batteries.
I have been chasing a charging problem but this seems to tell the story. I've had the coach only 7 weeks or so and have been going through all the systems and now I'm to the electrical systems/batteries.
So, I have in there now 2 - Marine RV Deep Cycle, SRM-24, 690 MCA, 140 RC for the house batteries which when I searched seem to be 12 volts each. After reading much on this subject in past and everyones opinions, I have the money so how about just buying these:
GPL-24T 12 Volt, 80 Amp Hour Deep Cycle AGM
I'm thinking of these because DW & I will be doing a lot of traveling in a few months and quite possibly some boon docking so this should give use plenty of hours.
But then again I can't seem to find these Lifelines anywhere here in houston. I'm open for suggestions.
These are my batteries now:
And, is there any special procedure to changing out these batteries other than, disconnecting from shore power, turning off the batteries at the disconnect switch, and then removing the neg. cable 1st? I know with changing the chassis battery you can have computer memory issues if you don't apply supplement power prior to changing out.
