Not necessarily related to RVs, however,
I removed the battery (Crown Deep Cycle, 2 years old) from our Slingshot and have had it hooked up to a Battery Tender Plus in the garage for a couple weeks now. While in the garage recently, I heard a sound emanating from the battery. The best description I can give of the sound is like an electric coffee pot percolating. It was brief, intermittent and only lasted a couple perks each time. The battery is sealed/capped straight from the trailer.
Coincidently, the first time I heard this was a few hours after BC Hydro came by and exchanged our meter for one of those new "Smart" meters and, in doing so, had to turn the power off for about 30 seconds. However, not sure if this is related. The correct green light is currently showing on the Tender.
As I have had other batteries hooked up to this device in the past and I have never heard this gurgling sound before from any battery, I thought I would ask if anyone here has any experience with this sort of thing??
Thanks in advance,
