Hi used my van this week and after 2 days could smell gas or rotton eggs turned out it was coming from the battery box. The battery was very hot and smelt realy bad. It has a vent tube coming out of battery but the smell was coming out of the top of batt.The battery was ok for water as i checked it before i went away.

Any help very welcome.

Kind regards.

sounds like the batterys had it it's sulphated hence the smell of rotten eggs. where you on electric hook up and over charged the battery or is your battery just old

Once had a rotten egg smell on a car battery and it turned out that the alternator was putting out too much charge and thus boiling the battery.

Were you on EHU at the time?

I am sure someone a bit more technical will be along soon.

THE BATTERY IS ABOUT 15 MONTHS OLD AND I WAS ON ELECTRIC.

THANKS.

leave the battery to stand for 2 days and check the voltage with a volt meter should be 12.65V or above if less you may have a cell gone down

On this issue if your van does not have a meter advising the charge level how long should you charge your battery for.     

Most modern caravan charging systems have a "float" facility built into their specification.  This means that when the battery is close to fully charged, the system keeps it in that state without overcharging it.  Most of the time, when my van is parked at home, the battery is on charge.  Sometimes I will switch off the charging for a couple of "rest days", but otherwise it is continuous.  My current (no pun intended) battery was transferred from my previous van, and is now about 4 years old.  It has always been subjected to this procedure.  It is a 110A/hr battery, because it has to deal with running the mover.

My battery box is sealed from the interior, and I thought this was always the case.   However, I would be concerned by an overheating battery, and would check/get checked the battery and the charging system.

Thanks for your comments all,

I rang local dealers were we got the van and they said its the battery because it was probably not checked as vans are not sold with a battery, I.E not any water in the sells. They checked the charge that was 13.8 volts so i guess it`s the battery.

Fingers crossed.
