Acidic maths

Your safe with the batteries as it's already diluted.
Adding water to conc acid is a bit of an attention getter.
Adding conc acid to water is quite safe if done gently. The more water there
is the safer, as the acid is diluted on contact.

It's still a bit exothermic though.

You know how you're always warned about not using a naked flame near a
charging battery? And you know how, when you're 14 years old, you have
a burning desire to find out if those things that adults tell you are
true? And you know how a 14-year old considers himself indestructible?

Well, imagine me as a 14-year old with a charging battery, a box of
matches and nobody else around...

 

Make a nice bang, did it?
Or did it just make an unsatisfying *pop*?

Oh, definitely a bang. It resulted in neighbours appearing in the
street talking about gunshots.

Injuries?

Same for other exothermic solutions. I'm sure I've already mentioned
here the cautionary tale of two lads who tried to short-circuit the procedure
for cleaning a large vessel at a local sugar-cane refinery by dumping several
bags of caustic soda into it and then starting to fill it with a fire-hose.

Boiling caustic melts flesh...

They vary.
The one that blew up in a foreman's face where I was working made a dull
thud.
Mind you, the stupid **** jump-started it with a welding set.

 

Yes, but the greater mass of the water disperses the energy so
that you don't get localised heating unto the boiling point that will
happen of water is dripped into (rather viscous IIRC) concentrated sulfuric.
[I still hate typing that; I wish IUPAC hadn't caved in to the Yanks.]
