Batteries
Neighbor Mike has a big Ford Expedition so we expeditioned ourselves to our local Sears Auto Center and picked up 13 Diehard Platinum P1s last Saturday. They are equivalent to the Oddysey PC1500 I was eyeing up, but about $50 less each so I’ll give them a go. The best part was customers weren’t allowed in the work area unless they had eye protection. Neighbor Mike jumped right in and helped loading, but in doing so took the only extra pair of safetly glasses they had. So I scoped out the vending machines while they loaded 650 lbs of batteries.
I did help unload and then moved them into the garage on a pallet though. I’d never heard it before but people are saying that leaving a battery on concrete will drain it. One idea I thought made sense is that the concrete remains cooler than the ambient air so the electrolyte separates at the bottom. The slight differential created eddy currents which drain the battery. I remember hearing about those at UF, but I don’t know what they are. I do know they aren’t used to build roads and were not on the PE exam.
