Sealed FLA batteries and venting
Sealed FLA batteries like Lifeline need to be ventilated correct?
Forum Discussion
I tried to find this out for my AGM (they are all similar in this respect). The consensus seems to be - yes, they are gassing but very little and only if they are overcharged.
Meaning - if controller fails in such a way that charging will continue full throttle after they have been 100% charged. Not a very likely scenario, though possible. There is no generator in my rig, so controller is the only one to watch out.
Also, - they vent "less" in this case. Since there are no numbers, I decided - call it a guestimate - that if placed in the front through-storage with many cracks both to the outside (around the storage lids on both sides of trailer), and to the inside (around the bed frame), and IF controller fails in the aforesaid way, - my AGM bank won't vent more to the inside than a wet battery in a car that I'm driving.
Again, - I couldn't find any hard numbers, and for my AGM the numbers can be different from Lifeline.
PS: I don't understand why even consider AGM (and costly Lifeline at that), when you can mount it outside.
