Faulty Battery Watering System?
A couple years ago I purchased a BWS to simplify the process of keeping the water levels in my battery proper. Every month or so I would get out the hand pump and give it a few pumps until the floats all popped up and cut off the valves indicating full. It appeared that the SOC was 100% always until the last time I took out the camper and I get a Low Voltage error from my auto level.
I then notice the SOC is 72%. The unit sits at a storage lot with solar so it should be full and it had been a few months since I visited. I give the system a few pumps and it appears near full. I have 3 12V Batts in parallel and noticed some corrosion on one of the connections so figure that might be the source of the problem. I remove all three Batteries to inspect/clean all the connections. I remove the BWS and surprised to find several cells are low on water. I verify the floats, water flow and cutoff on the valves and all seems ok. Yet, when I test the fill again the valves pop up and cut off the flow on certain cell prematurely.
Not sure if I am doing something wrong or the system is broken or the system I have is junk? I really like having the system since it is not practical to fill the batteries without it.
The BWS gave me a piece of mind and added simplicity to this task but now not so sure. Has anyone had a similar issue or any info that may help?
I manually filled the low cells and am charging the batteries now but suspect they may be gone. Might be time for AGMs
fyi, the system I have is: BWS
