Flat leisure battery!

I bought a brand new swift challenger(my first ever caravan) last May and put it in storage over winter thinking the solar panel would maintain the battery charge. But when I visited it last week there was no power so the alarm and control panel (or anything else) didn’t work. I’ve checked all the fuses/trips etc and they seem ok. So I checked battery charge and found it’s only 3.8 volts!

the caravan has an alarm and tracker so I’m wondering if they’ve drained the battery.

any advice you can give would be most welcome especially about is the battery now capable of being recharged/if not is it covered by the warranty/can I do anything to prevent this happening every winter?

I had a tracker and alarm on a caravan but no solar panel and the battery would last 1 to 2 months before needing topping up. The solar panel should be more than capable of keeping the leisure battery charged if the van is not parked in shade. It sounds as though there is a drain on the battery as suggested by others and you need to isolate the system. I believe it’s a Sargent system on the Challenger and, if so, it should have a shutdown button. Alternatively, the leisure battery was faulty.
