Fair enough. Bill, it's common to develop a maintenance cycle for lead acids. Because they lose capacity over their usage lifetimes most people recommend replacement after a year or two of usage. How do these compare? Assuming no 'abuse', how long will they last, and should they be replaced on a schedule?

Also, will they lose charge while stored, and how quickly compared to a lead acid? Will a lead acid trickle charger work to maintain these, or is something special required?

Thanks,
Chad
