Carlos, I'll give it a go:
I dropped over 300lb going to Li. I can charge this baby at 34 amps, that's the equivalent of 132 amps @ 12v. There's no long absorb phase. There's no harm in sitting undercharged. I never have to water. I never get corrosion. At age 70 these are the last batteries I will ever buy - I seriously doubt I'll be alive in 30 years. And, the best part is, I can afford it.
