Hi All,
Hi All,
Well my ALUM showed up from Nuts.com today so that got me in gear. I went out and bought a Auto Craft, Power Sport Battery Model 4L-BS 4Ah dry charged. I left the acid at the store. Filled it with a very strong mixture of ALUM/Distilled water 1.5 Cup distilled water and 1/3 cup Alum, dissolved Around 150 degrees in the water. Battery measured 8.28 VDC with no charging done to it right out of the gate. Started with a 2A charge but had to lower it to 0.5 A after 15 min as battery was boiling. We will see what we got this evening. Big battery still on discharge so have to wait till it gets off dis-charger but might use the power supply as a 0.5 amp reverse constant current load and measure its capacity in my watt meter. This will be a much more manageable battery!! I'll know what I have later today.
