Permaniant magnet charging systems like that typically put out around 20 amps max. + or - 5 amps to that 20 and it covers pertty much everything.
Your discharge rate life expectancy does have some relationship to charge rate life expectancy.
The optimia batteries I use at work have an absolute max charge rate of 60 amps. Max recomended charge rate is 40amps and most of my equipment charges its optima battery at a rate of between 10 and 20 amps and they last a long time.
They also weigh 44lb.
Back when I use to work with smaller batteries about half the size of the optima on lawn and garden, motorcycle and ATVs I figured you wanted to charge them no faster than 1 amp per pound of battery.

Did you ever put an ampmeter in line with your battery to see how much alternator power is soaking up?
When ever I have used deep cycle batteries, even hundreds of pounds of them all in one stack I have only used up to 20 amps to charge them.
These batteries are 6 volt and slightly larger than the batteries in my truck, each cell is more than double the size of the cells my starting battery.
