There's a subtle difference. One is designed to release that energy in a fraction of a second in a frangible metal casing, the other is designed to release it over a number of hours. Yes, batteries can go wrong, just like any tech, but comparing them to hand grenades is just ludicrous.

Next, let's calculate the energy input required to heat a small cup of coffee and compare that to a hand grenade. (Hint: The coffee wins easily.) I wonder how many hand grenade equivalents a 10 minute lukewarm shower equates to?

In some universe there's an internal combustion shower powered entirely by an operator ripping out pull rings with their teeth and throwing armed grenades into a heating chamber.

Preferably yelling 'fire in the hole!' each time.
