So, inside a garage, the hygrogen filled up the whole place? Must
have
been one hell of an explosion.

It must be that there's no breeze inside, so there isn't that much
hydrogen but it hasnt' spread out yet.

We should dye all the hydrogen blue. Then it would be easier to
figure out where it is.

For the OP, I've yet to see a starting battery that couldn't be
charged with a slow charger
while still connected to the engine without doing damage. People
routinely leave
battery tenders hooked up to all kinds of engines in everything from
cars to generators
without disconnecting the batteries. That's what I would use to keep
it charged.
