Do D constitutes a full charge followed by a discharge to the indicated state-of-charge (So C) level in the table.

Table 2: Cycle life as a function of depth of discharge.

In lieu of cycle count, some device manufacturers suggest battery replacement on a date stamp, but this method does not take usage into account.

A battery may fail within the allotted time due to heavy use or unfavorable temperature conditions; however, most packs last considerably longer than what the stamp indicates.

There are good reasons to be optimistic as lithium-ion is, in many ways, superior to other chemistries.

Most Li-ions charge to 4.20V/cell, and every reduction in peak charge voltage of 0.10V/cell is said to double the cycle life.

The performance of a battery is measured in capacity, a leading health indicator.

Internal resistance and self-discharge also play roles, but these are less significant in predicting the end of battery life with modern Li-ion.

The batteries were then discharged at 1,500m A to 3.0V/cell, and the cycle was repeated.

The expected capacity loss of Li-ion batteries was uniform over the delivered 250 cycles and the batteries performed as expected. Eleven new Li-ion were tested on a Cadex C7400 battery analyzer.
