The CM's handle that just fine - why couldn't they exchange far less messy (and toxic and flammable) sealed batteries instead?
Because if they choose a higher energy density chemistry battery such as most Li-ion flavors, it has the potential of thermal runaway. Are all the CM's going to be trained on proper techniques on how to address a Li-ion fire? It is not a simple fire extinguisher. This goes back to my previous post about using a sealed AGM or VRLA Pb acid battery, but this is not an innovative battery technology.
"If a Li-ion battery overheats, hisses or bulges, immediately move the device away from flammable materials and place it on a non-combustible surface. If at all possible, remove the battery and put it outdoors to burn out. Simply disconnecting the battery from charge may not stop its destructive path. "
"Heat combined with a full charge is said to induce more stress to Li-ion than regular cycling. Keep the battery and a device away from sun exposure and store in a cool place at a partial charge. Exceeding the recommended charge current by ultra-fast changing also harms Li-ion. Nickel-cadmium is the only chemistry that accepts ultra-fast charging with minimal stress. ".

I will disagree with their last sentence as we used NiMH and proved ultra-fast charging with ultra-low stress far exceeding any battery known at that time.
