Keen to learn from the chemists/technical or battery experts out there.
Loaned the caravan to my daughter for the weekend. When it was returned MM was playing up, checked battery voltage and it was11v. Plugged in 240v, all was fine. Thought little more of it. Perhaps daughter had unplugged EHR early onsite and drained battery a tad. Next morning I could hear the Carbon Monoxide (CO) alarm kicking off. The alarm was close to its 7 year expiry so thought little more of it. Just opened the rooflight (just to be safe). That evening I turned off the gas supplies just to be sure nothing was burning. Next day, mid morning, CO alarm kicking off again. I checked the battery compartment; the battery felt warm but nut not hot. I phoned Fire angel and explained the situation and they explained that my CO alarm was a duffer. Whilst googling to find a replacement CO alarm I noticed that the alarm was reading 0ppm inside my house. This led me to think that perhaps the CO alarm was actually working correctly. Used different CO alarm from house in caravan and to my shock it also kicked off. Replaced leisure battery. No further problems.
There were no smells coming from the battery. The old battery since checked by the local garage who confirmed it was knackered. There were no other technical indications that anything was wrong once plugged in to EHU. So my question is: could we have been in danger had we used the caravan without a functioning CO detector? And also (one for the chemists or battery experts) why is a knackered battery giving off CO when being charged.
