I've got Lead/Acid , 12 volt batteries. Some are 12 volt 12 amp/hour, left over from my experiments with electric assist (ebike).
The 12 volt 7 amp/hour is still my favorite.
I think I have a run time of ten or eleven hours with the 7 a/h battery.
I tried a 4 amp hour lead acid motorcycle battery, but had some issues with the extreme cold , temperatures below 20° Fahrenheit , which could be the cold, but also that type of battery is designed for "cold CRANKING Amps" (CCA) , so it does not have the run time that a normal AGM, SLA would have.
Heres a photo of the 4 amphour MC battery , at the bulkhead:
