IF those L 16s are much over 5 years old, they could be gone. L16s (of any
brand) have less cycle life than a golf cart battery, just check the charts.
They also don't fair very well long term in float charge.
You can probably EQ them back to life as already mentioned, but then after 6

L16s do have the advantage of holding more water, so I think that might be why

Your table shows just what I found as well: too large a battery bank actually
isn't as cost effective.
Also, based on the Trojan chart, you can see that a regular L16 isn't even as

The aux off is only if the generator doesn't start. You need to set the
gen start voltage higher. Aux off is last ditch shut down, set for 44v
