I've found the Zephyr Power vents to be a little undersized in
larger batteries with arrays over 1000 watts. Still get that smell
in the room outside of the battery box, though its not explosive.
That was with the 12 v model. I wouldn't mind seeing someone make a
similar vent plumbed to larger pipe with about double the flow rate.<br>

Thanks for the follow-up on this subject. I'd like to change the
example to show the ventilation required rather than the hydrogen
liberated. <br>
<br>
Consider a 48-volt bank of L16RE-B batteries: that's 24 cells of
370 amphours. Using the 14 cc/hr/Ah/cell H2 rate for equalizing
gives a total hydrogen of 124320 cc/hr or 124.32 liter/hr. To keep
the hydrogen concentration down to 1% would require that the total
ventilation is is 12432 liter/hr or 12.432 cubic meters per hour
or 7.3 CFM. A 12-volt Zephyr battery vent will move about 6 CFM,
that enough to keep the H2 concentration down to 1.2%. Zephyr
Industries claims the vent is suitable for 2200-amphour (12-volt)
battery banks which is six 370-amphour batteries. I've seen too
many battery boxes with no ventilation or with a single Zephyr
vent for 16 or 24 batteries.<br>
<br>
There is a DIN standard (EN 50272) for ventilating battery rooms.
The calculations for it are based on an assumed (electrolyzing)
current for various charging voltages. The main reason it is
interesting is that the ventilation requirements come out about to
be twice as much as when using the H2 rates you provided. I
suspect that is partly because it is intended to to cover all
batteries and it is intentionally conservative.<br>

“float charging” mentioned above is kind of confusing to
many. Indeed, there should be no mention of gassing during
“float” charge mode, since we are below gassing voltage.
It is mentioned for info here although not typical for
deep-cycle products: the Hydrogen production is only a
concern for UPS type of applications, where the battery
stays at float charge for several days /months. Float
charge mode is actually meant in “float” applications to
mitigate the self-discharge of the battery due to its
natural self-discharge. Indeed, even the very small float
charge current build up hydrogen over time. Note: VRLA
technology will generate less Hydrogen than flooded since
the required float current will be less for VRLA
technology (0.2 to 0.5% of C/20). Sorry for the confusion
to cyclic applications minded Wrenches.<o:p></o:p></span></p>

be advised the “boost” charging is only acceptable on VRLA
AGM, not VRLA GEL. It has the same role as the regular
equalization event: to equalize the cells, although for a
much lower voltage and very limited time. The “boost”
charging is often not activated as a safety precaution on
poor charge algorithms.<o:p></o:p></span></p>

keep in mind that the above are approximations, as, when
lead acid batteries issues are involved, “it depends” is
the first words you hear from battery OEM’s. Hope this is
helps.<o:p></o:p></span></p>
