How long is a cycle in battery life?
Each round of full discharge and then full recharge is called battery cycle life. A battery's cycle life can range from 500 to 1200. That means a life cycle of 18 months to 3 years for a typical battery.
[Note the term "full discharge". I imagine most people do not let their battery go to 0%.]
Just to clarify, "full discharge" is a cumulative computation, i.e., 20 x 5% discharges = 1 full discharge, as do 2 x 50% discharges.
Quite true. And the discharges can be over a period of days or weeks, so that the duration of a life cycle can be even harder to determine. That's why I think the maximum battery charge, rather than cycles, is a better indicator of battery life and power. And in the case of this thread, to me, 23% (or now 24%) is not a good sign.
I agree. % charge
is more important than number of discharge cycles...considerably more important, in fact. And you're quite right about Rita's battery taking only a 23/4% charge being ominous (and that's to say the least).
But it seems to me that there should be some degree of correlation, and a battery that's only used up 1/4 of its life yet only takes 1/4 of a charge seems anomalous to me.
Has anybody got any insights into that?
