Table A2: Estimates the number of discharge/charge cycles Li-ion can deliver at
various DoD levels before the battery capacity drops to 70 percent. DoD
constitutes a full charge followed by a discharge to the indicated state-of-charge
(SoC) level in the table.

Partial and random charge is fine; does not need full charge; lower
voltage limit preferred; keep battery cool.
Constant voltage to 4.20V/cell; no trickle charge; battery can, no trickle
charge, battery can stay in charger
Rapid charge = 3h (recommended)
Fast charge = 1h
Prevent full cycles, apply some charge after a full discharge to keep the
protection circuit alive.
Keep cool. Operate in mid SoC of 30–80%. Prevent ultra-fast charging
and high loads (most Li-ion)
Store at 40% charge in cool place (40% SoC reads 3.75–3.80V/cell). Do
not go below 2.0V/cell.
Low toxicity. Can be disposed in low volume. Best to recycle.

4.2 V/cell (8.4 V for IsoLED Plus +)
4.2 v – 3 v = 1.2 v/cell = 29 % (For minimum
of 1000 cycles)
1.3 A = 1.3/3.5 = 0.37C Charge Rate

Table A2: Cycle life as a function
of
depth of discharge.* A partial
discharge reduces stress and
prolongs battery life, so does a
partial charge. Elevated
temperature and high currents also
affect cycle life.
Note: 100% DoD is a full cycle;
10% is very brief. Cycling in mid-
state-of-charge would have best
longevity.
