Can batteries test "ok", but still be bad?
Let me begin by saying I have no knowledge/skills when it comes to all things mechanical, etc. This saga begins when I was parked for 5 mo season, and used a battery tender on the engine start batter...

OP back, with a couple of follow up questions. The tender is hooked up to the 2 engine start batteries, not house batteries. Those engine batteries should have been fully charged from 2 days of driving, when the tender was connected. Am I to gather that I should not base battery condition on the fact that the tender is not indicating "charge/float"? Would I be better off using a trickle charge system? I am plugged in to shore power, and will be sitting for about 3 mo before heading to FL for the winter.
Your post is a little hazy to me.We fully realize its the chassis batterys the tender is hooked up to so not sure why u said that.?
You said and I quote here"Those engine batteries should have been fully charged from 2 days of driving, when the tender was connected."
The Battery tender does nothing when driving the unit and your battery has a fair amount of draw when driving.SO after stopping and pluging into Shore power to activate your battery tender it would take about 24 hours for the tender to say or indicate fully charged
Also to note its not to say your tender is not operating correctly and giving a false reading.Take a volt meter and see what the battey voltage is.Its should be in the 12.7V range or slightly higher
