Re: Dead house batt

Actually you probably know how your battery preformed before and it should still be the same. Each type of battery can be slightly different so Concord who makes Lifeline batteries should have the info on their site. You might see a chart similar to this below for AGM batteries but you have to figure in time and the amps being used. This has been asked before and if I find the link I'll post it.

State of Charge Specific Gravity Voltage
12V 6V
100% 1.265 12.7 6.3
*75% 1.225 12.4 6.2
50% 1.190 12.2 6.1
25% 1.155 12.0 6.0
Discharged 1.120 11.9 6.0

I have a friend who has a carbon pile tester that I use which comes with charts and takes the math out of it.

Re: Dead house batt

Update... The first overnight charge didnt really work out. I came home the next day and for some reason there was no power coming from the outlet. The batt was drained again. I removed the plug and switched outlets. Power was back on. I then had the van plugged in for 4 days. I unplugged last night and this morning still had a full charge! I know its only a few hrs but I think it is a good sign. I will unplug for a day or two and see what happens.
