After installing my RedArc Dual Battery System, I got to wondering Battery life and my ARB 78L Fridge. How long would it last for, and how long it’d take to recharge the battery on my RedArc Dual Battery System. So I did a quick test. Well, not so quick as it turned out.
So I must admit that I wasn’t very scientific about this. My tests involved basically running my fridge at home for a few days. The fridge, inside and was empty and set to 4 degrees C. When the battery reached approximately one third of capacity, I attached it to my dual battery system and went for a drive to see how long it’d take to charge.
And when I say I wasn’t very scientific, I really mean it, OK.
- The battery is a Century 100 Ah AGM deep cycle battery.
- The fridge is an ARB 78L fridge with the canvas cover
- The Dual Battery System is a RedArc SBI12
So my very unscientific results are:
From full charge to one third battery capacity, running my fridge in my home at 4 degrees C took 72 hours.
From that point to full charge took approximately 34 minutes. I drove for 17 minutes initially and tested the battery capacity. it wasn’t fully charged. I then drove home again (another 17 minutes) and by then the battery was fully charged. During this time, the battery was only connected to the charger. I.e. it was not providing power to the fridge any longer.
So in summary, the battery will run the fridge for a long time. And the battery doesn’t take much time to charge up on my Dual Battery System.
