House Battery Not Holding Charge , Bad Battery or Converter Issue?
Hi everyone,
I’m having an issue with my RV house battery not holding a charge for very long. Even after being plugged into shore power overnight, the battery seems to drain pretty quickly once I disconnect.
Lights dim faster than expected, and basic 12V usage doesn’t last long at all
I’m trying to figure out whether this is:
A weak/aging battery
A converter not charging properly
Or possibly something else in the system
I haven’t done detailed testing yet, but I’m planning to check voltage soon.
Has anyone experienced something similar? What would you check first in this situation?
Any guidance would be really appreciated
