As someone that has been involved with phone systems maintaining up to 300 amp-
hour 48 volt lead-calcium batteries for PBX backups (ok quite a few years ago)
I would agree with Rocket.
We could recharge that battery within a few hours and had a vent fan for the
switch room. It wasn't a much different than a normal fan for a commercial
grill at a restaurant.
The customer was an electric utility and didn't care much about the wear and
tear on the cells due to pushing the charge rate. Or the cost of electricity.
They just swapped out entire batteries regularly.
And it was still way overventilated.
Of course explosions being what they are...
