Indeed.  Keep the battery in the [30%,85%] charge interval.  Stop charging
when it goes from burp charge (yellow led) to tickle charge (blinking green
led).

But it *will* still be at 50% original capacity after two years, unless you
live in a very cold climate (when it won't work right anyway, soo... :) ).
