Vapor density of battery gas.

[bertro]

I know have learned my lifeline can produce gas. I have the orig. cap on the battery that is sealed down pretty good. What might the vapor density of this gas be so I know if I should vent above or below the cover. Thanks Robert.

In my safari the battery vent exits out right above the back access hatch, which is about 6" higher than the top of the battery. I don't think the density has much to do with this though because the expanding gas will create pressure which will push the vapor out weather you go up or down with your vent tube.
Good luck, Rich

The gas generated during charging a lead-acid battery is Hydrogen Gas.
It it lighter that air.
That is why the vent is higher than the battery box.
It is also flammable, and can be explosive if it is at the right concentration in air.
It is therefore very important to properly vent it.
This is similar to Methane Gas which can be generated from eating too many beans.
I have been told that exterior venting is best in the latter case.
Good luck

Overcharged lead acid batteries produce hydrogen gas, which is obviously explosive if not properly vented. Hydrogen gas will rise -- that is why the battery compartments are vented up top.

I'm curious. How did you learn that your Lifeline produces gas? I thought they were well sealed.

I just noticed it on lifelines website. My vent port is not easy to hookup without removing the inner skin. I was just wanting to vent through the floor. Thanks for all of the replys. Robert.

I was told they shouldn't unless the case is compromised.
Hope it's true!! "designed to reduce outgassing under normal charging conditions"
They are in the Classic compartments, kind'a tight in there and smallish vents 'ta boot.

Guy's read the manual! ALL Lead Acid Batteries will off gas Hydrogen when charging. You must vent.
