I'm living in an off-grid house with battery power storage. Batteries are one of the most expensive and problem prone aspects of off-grid power. I have a battery bank in which some of the batteries are experiencing positive terminal growth. This is when the positive terminal literally grows longer and starts to push its way out of the battery case.
The batteries are 2v 460 A/hr Gel Batteries (sealed lead acid). I have 24 batteries running in series.
I have not had much luck finding out exactly what causes this and how to avoid further worsening of the batteries.
Does anyone know the exact causes of this, or whether it's possible to reverse it?
