So I started testing my batteries with a optronics H3 50W light. The battery is a 12V, 7 Amh SLA. They are free and hope to put them to good use. I can get 1 hr(or a little more) bright burn time with this set up. It was still burning at 1.5 hrs but was a less bright yellow light. If I switch to 2(flood and spot) 20 W MR 16 lights, what can I expect as to burn time.
What happens to SLA if they stay out overnight during winter? I have to leave a bike at the train station everyday.
Thanks all. Charlie
