I was doing a research for my customer. I ended up reading the Battery Life and Performance Factors on CivicSolar.
Here you mention that Gel batteries are more advantegous in terms of life cycle. I understand that the author has referred to MK/DEKA Battery technical document from where I take the below snapshot.
However, I was reading another article on this link (2nd snapshot added below) which mentions exactly the opposite: The AGM battery life cycle is higher than that of Gel batteries.
The question is; which one is correct?
