I don't know about battery tenders, but I have known people that had batteries explode with a trickle charger. Charging a battery can release small amounts of hydrogen gas. They had the battery in a confined space that allowed the hydrogen to build up. Then they disconnected the charger cables while the charger was still on. The resulting spark ignited the gas and caused a small explosion. Luckily no major damage or injury.
