typoFor charge maintenance on a charger, I guess a different restart-charge voltage might be used than in an intermittent drain application.
Presumably in a charger, a voltage is picked that a cell is unlikely to quickly discharge to after being charged up?
One scenario on a bike could be a stop-start pattern that results in charging being repeatedly triggered, so the cell is almost permanently in a state of being charged, possibly hovering around the retriggering point, or maybe continually being just topped up to cutoff point, then cycled back down to the retrigger point. Presumably in a case like that, the lower the retriggering voltage, the better for the cell, though at the expense of possibly reduced stationary runtime.
However, could it be that somewhat deeper cycling and/or a lower maximum voltage would actually end up over time with a greater [average or minimum] stationary runtime, compared to a system based round a less-well-treated cell which was kept more topped up but [hence] lost capacity faster? Much might depend on the pattern of cycling, and the frequency of light use.
