Fair enough. But if it is in an electrical device with shoddy glue that is likely to catch fire or explode, then it would be nice to not be given a lethal dose of lead in addition to my place burning down.
Personally,.I would much prefer my odds as an adult in a lead poisoning/fire situation than a similar li-po situation. Going with the more complex battery is basically choosing a future of experimental medicine over treatments with long and successful track records.
