Battery Storage Charge Profile
Well I've gone and done it. I pulled my group 27 marine yesterday evening to move it to the boat in preparation to catch some spec's ahead of the storm blowing in today. I use this battery on my troll...

My single mode charger boiled out one of my batteries in about three weeks. This was only putting out 13.6VDC...
Now I have a smart mode PD9260C Converter/Charger which puts out smart mode charging DC voltages...
This does the 14.4VDC - 13.6VDC - 13.2VDC and once every 19 hours will run about 15 minutes putting out 14.4VDC...
I use to watch my batteries after installing this unit but always found them in good shape...
It does everything automatic now when I leave it running off of home shore power...
Here lately however I have been doing a complete disconnect on my stored batteries and if they start out being fully charged then and reading 12.7 or so VDC just sitting there they will very slowly start dropping their charge.
Over the winer months it will take a couple of months for them to get from the 12.7VDC to the 12.5VDC readings. When I see that I will connect the batteries and turn on the PD9260C converter/charger again to bring them back to their full 100% charge again...
I have one GP24 battery setting here in my radio room that has been sitting here in a box disconnected and reads 12.6VDC and will occasionally flicker down to 12.5VDC... I can switch in my standby 600WATT PSW Power Inverter and it will run a couple of 120VAC emergency lights for hours... This is my last good GP24 12V 85AH battery from my original battery bank here.
I am currently in the planning stage to redo my trailer battery bank using two groups of T105 6V batteries in series to give my a good 450AH capacity 12VDC battery bank... Just about got my metal battery box all drilled out and fitted with BLUE SEA Switches, meters, and lug terminals components for monitoring and distributing my 12VDC power requirements. Waiting for money to purchase my Trojan T105s Batteries from a local golf cart dealer here where I live... This will all mount on my trailer tongue area in a 58-inch Torklift Battery box with top slide where my older 12VDC interstate set in plastic battery boxes... Gonna be a Perfect Fit within the one inch welded on Battery tray angle guides...
