A refinement to the batter life question question is, after how many charge/discharge cycles does the charge capacity reach 20% of its original capacity?
We can then divide that number by our respective number of charges per week and arrive at a life duration.
If you could provide a graph with capacity over charges, that would be great, since others may wish to use a different % as the minimum. For example, someone with he 160 mile battery might want a minimum 45 mile range, and thus 30% is their threshold for wanting to buy a new battery.
A decay graph would also help us choose which battery to buy based on cost-justification and computing the expected life.
