Battery Monitor

[Landrover]

Using the Sea level II monitoring system on the Elite II  for  battery monitoring of the 4 AGM battery’s it appears that a full charge shows 13.2 volts  what  should those numbers look like in different stages of discharge.  Full charge 13.2  to  discharge volts? to the lowest voltage rate before recharge is needed or completely dead battery ? these voltage numbers can help if  no elect hook up, and no Solar panel for recharging.  Thoughts  Thanks

Does this help you?

Understand that the seelevel displays the status of the moment. If your batteries are under load (furnace fan or water pump running), you'll see a lower voltage displayed, and if you are charging, you'll see a higher voltage.

Wait 20 to 30 minutes with no load or charge to let the batteries settle down to get a somewhat accurate reading.

Not sure?  Aren’t the Ollie battery’s (4) 6volt AGMs your chart is for 12volt Single?  would it be the same results?

Essentially  the same,  as each 6v pair is wired in series, then the two pairs in parallel, for a 12v bank.

Your battery manufacturer may have a more specific chart for your brand and model. 

I try to run ours no less than 70 per cent, to sustain battery life,  And be able to charge to full each day. LA batteries don't love partial state of charge, though a day or two below full probably doesn't make a big difference.

Yep - what the Dawg said. 😉
