Here's what i'm wondering, in these cases of thermal runaway on Li aircraft batteries: (1) how many owners routinely used a "trickle charger"? (2) how many tried to "deep cycle" their Li battery? (3) how many noticed the battery was not maintaining a charge, but just continued using it, assuming the alternator would charge it up; then, they'd just plug it into the trickle charger when they get home? (4) how many tried to recharge an Li battery with charge of 6 volts or less? (5) How many put their Li battery on a charger in cold weather, cause it seemed to be weak? I've been carrying a lithium-ion polymer battery in my front pocket (same one) now for 3 years. It hasn't shorted out internally yet. And, I've had a couple of other cellphones with Li batteries, never had a problem (no Samsung for me! and, those were recalled anyway). ....So, my unscientific deduction is that, since all the big recalls early on, most Li aircraft battery failures that are happening now are from misuse.
