Relying on an engine alternator will not properly charge a
deep cycle battery long term. Economy trickle chargers do not help.

Here's a good easy read on batteries talking specifically about the
Optima
vs. other types,
And a good breakdown on why the 3 stages of charging are important.

I never realized how much there is to batteries.
The world seems to be asking for a really really good way to store
electrons.
I hope someday soon we can look back and laugh that we used these heavy,
acid fume producing potentially explosive batteries. .
