batteries
$begingroup$ As for why it exploded (and not just got warm or did nothing), this is because lead-acid batteries produce hydrogen gas while charging. Normally, this is vented to the atmosphere as it''s created, and it harmlessly floats away. However, in a damaged, vent-hole plugged, or heavily-used battery, a lot of hydrogen can collect inside or near the battery.
