Food for thought: lead-acid batteries are the most recycled things on earth, at around 99%. Probably because they tend to be large, so they have a high volume to surface ratio, and are relatively simple and easy to recycle compared to more modern battery types, and many automotive related companies are required to have recycling programs for them, and they've been around for many decades ...
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.
