No...but it does explain some things about you Ed!
Vent it anywhere you like. The whole idea is just to get some air flow in there so there is no accumulation of vapor.

No longer posting. Reach me by PM!

BTW, Hydrogen is pretty good at escaping... Helium isn't as active and look at how it does from sealed mylar balloons. You probably don't need a whole lot of venting for a battery long as the vent is at the top of the box... Hydrogen rises...fairly rapidly.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Trojans are not the only choice for wet acid batts.
Interstate makes 225Ah. 6V that are pretty good also. They hold more liquid are heavier and have better construction.
I've had six of them in my Endeavour 32 for 8 years now maintained only by my AirX turbine...they lasted 8 years and I wasn't very nice to them. I bought 2 Rolls Surrette 8D's because I got them for a song at CE Beckman's.
But I was pleased with the Interstates.
And...There is no such thing as a "maintenance free" batt.
