Great battery, though it is FAA approved for what that’s worth for the price it should be lithium, thus is certified aviation though

Q: Can this battery be charged and maintained with a 24volt battery tender? I ruined a Gill battery with my battery tender. Upon review at Deltrans site they specifically mention Gill Batteries not being compatible. Is this battery different?
