Battery Venting

[HUGGY]

Hi All,

Now have 2 x Banner 110 amp wet batteries in my Bailey MoHo. Housed in a twin battery box which is set into the floor. Currently have 1 x vent tube venting through the floor. Question is: When I fit the second vent tube is it in order to connect both batteries via Y connector and then use the existing vent hole for both, or should I vent them individually and put another vent hole in the floor.

Thanks,

Ensure you all stay safe and well

When I fitted 6 lead acid batteries in my van I fitted a vent tube for each one

I bought a 5mm mixed bag of tube connections and a piece of 5mm tube from B&Q. Cheap as chips. Tee them together, there's no pressure the just need pressure release in emergency

We have three batteries & I have them all venting individually.

Not trying to hijack the thread.... Is it correct that I can plug one end and vent the other? (Normal acid leisure battery).
And then put pipe through hole in the floor?

yes
thats exactly how it works

Huggy,when I fitted an extra battery on my van,
I did as you have suggested and used a Y connector to link the vents into one out through the floor.

Many thanks to all for your comments and suggestions

Yes to the Y or T connector, theres no pressure in the tube so could probably link quite a few this way or use gel batteries which don't need venting.

My CO alarm goes off from battery fumes when it is sunny and on EHU. So I vented the end vents to a plastic tube which goes outside and it still does it. It has three leisure batteries and they all connect to the vent tube and it goes out to atmosphere. Maybe two vent holes per battery but I never looked for any, all my bike batteries have one and so does the car one.

As the battery will fit many vehicles they normally have two vents so it can be vented left or right, rear or front (depending on orientation of battery) using the shortest tube. .

I found there, IS ,vents at both ends of the batteries so I have now plugged the open vents and depend on the gasses going out the breather pipe. The original Hymer leisure battery is already plugged at the rear so the other two are sealed now. maybe the CO alarm will stop wailing when on charge from EHU.

I am mildly surprised that a CO2 alarm is triggered by Battery Venting, The gasses produced are O2 and H2, not CO2, with small amounts of H2SO4 vapour.? As for venting, I had one in the base of the wardrobe in a Battery box sealed, and vented to the underside of the Van via 1" tubing which also conducted the cabling

There are no CO2 alarms they are CO carbon monoxide Not dioxide. The alarms are triggered by the venting hydrogen you breathe out carbon dioxide and any sensor would be going all the time.
