Battery Warning lethal gases

I presume the sealed type of battery (ie no vent) would just explode?

I too have a Sterling van and my friend has a Swift but the same group. I just wonder how many fires are as a result of batteries over heating, I'm sure someone knows the answer to this problem but more importantly how can It be avoided.

The U.K. seem to have followed continental practice and fitted sealed lead acid batteries inside. Ours is in a plastic battery box under the bench seat and as far as I am aware there is no vent tube. They don't vent anyway but have an emergency release valve. Not much use for catastrophic failure and definitely a risk which is mitigated in our motorhome by having a Sargent system which should control the charging current.

It is true that an ordinary charger will continue to push current into the battery even when fully charged and this is more of a safety risk. So if you have a simple system like this you should not leave permanently on hook-up and after discharge you should disconnect and recharge with a smart charger.

I,m a bit confused, the original post say's "if the battery fails" how did the battery fail? it sounds to me that the battery was over charged, that is not the fault of the battery but the charging device! If the original post just replaces the battery the chances are the the new battery will go the same way as the previous one did.
