IIRC, LA batteries will last for 5-7 thousand charge cycles when batteries are only slightly discharged (~80% charged). Same battery good for 5-7 HUNDRED cycles when discharged over 50%.

You and Allegro are essentially saying the same thing.

Regardless it's good to know. I may have known that about LE batteries, it just hasn't occurred to me the way you both described it. Now it's more clear to me.
