Just been down to check daughter's caravan in readiness for new season. Been there since November with no charging what so ever during this period. Out of interest measured battery it is showing 12.39 volts. What does this tell me about the state of it? Any advice welcomed,

To measure it properly is very much more complex and needs the makers performance charts, frequently hard to come by. It really gets all too complicated, so I would wait to see if it does what is asked of it adequately, as I assume it once did.

Relax, I passed out well before charging had really got started although It was me in trickle mode
. I do hope the battery is in a better condition than me this morning. Think I'll leave it on the MH until tomorrow (48hrs). Will update after the weekend as to what appears to be the result. Who knows?

Took battery off van and its charger at 4pm yesterday. Left in awning overnight, very cold.. My multimeter gives a reading of 13.3v just now!

Sounds good Micky.
How useful the battery will be for your daughter depends also on what use she asks of it, if she is only an EHU user with modest mover requirements then probably its loss of ability to hold a big charge will go unnoticed. Where it will have ramifications is if her use is extended off EHU camping where retention of capacity is all important. From Ocsid is bang on

Posted on 07/04/2019 20:33 by mickysfWe will see, it'll stand for a week off charge before being put back on charge in the daughter's van. Wonder what it'll register then? Electrickery, don't you just love it!😉
