Just had a frightening incident. Alarm sounding in the caravan and on checking found a dreadful smell. Took me a few moments before I realised what was happening. Yes the battery was rapidly approaching boiling point. However, I was in time to shut off the power and save it from exploding.
The question now, was this just the 5 year old battery at fault or the charger. I will try to check the charger output tomorrow, but if this does not look good, then I will seek to replace the psu.
It is from a 2017 Coachman caravan, a PS276-1-BCSM unit. I gather these can be problematic and have come across a company called APUJACK who claim to make an improved and upgraded version of this.
I would welcome any comments on this topic and has anyone tried an alternative replacement for this psu?
Quite a few members have used Apuljack with only good things to say about them.
------------- XVI yes?
As well is two words!

Remember, if you buy something you bought it, not brought it.
Far more likely to be a charger problem than the battery I would have thought. However, having said that it is possible that the faulty charger has now damaged the battery. I don't know anything about that particular charger though.
Have you checked the charger without the battery connected up as you will receive a lower reading if the battery is currently under load from the charger?
Checking the two battery terminals independently with a live feed will provide an accurate reading with a voltmeter. It should read about 14 volts which if it's anything less then it proves that the charger is defective. Also check the battery independently too which gives you a positive answer as to which of the two are at fault or both but having a nasty smell from the battery means the the battery has over-gassed which might mean a replacement battery anyway.
My leisure battery is 10 years old and still going strong but I keep it charged 24 hours via a smart charger which helps prevent the battery from sulphating.
