Charge to test voltage at room temperature. Disconnect parts from
voltage to remove charging effects. Discharge cells with a constant current
(4 mA) noting voltage and time 1 and 2 seconds after beginning discharge.
C = I * dt/dv
Charge to test voltage at room temperature. Disconnect parts from
voltage to remove charging effects. Note voltage and time 5 minutes
and 25 minutes after disconnecting. I = C * dV/dt
Measurement frequency @ 1kHz; Measurement voltage @ 10 mV
at room temperature
Apply test voltage at 70ºC for 1000 hours. Allow to cool to room
temperature and measure Cap, DCL and ESR
Maintain at 70ºC for 1000 hours with no voltage applied. Allow to
cool to room temperature and measure Cap, DCL and ESR.
Maintain at 40°C / 95% RH for 1000 hours. Allow to cool to room
temperature and measure Cap, DCL and ESR.
Apply an increasing force in shear mode until leg pulls away

Place cells into an oven at –20°C for 30 minutes
In less than 15 seconds, move cells into a
70ºC oven for 30 minutes
Repeat 1 and 2 for 100 cycles
Apply a harmonic motion that is deflected 0.03 inches
Vary frequency from 10 cycles per second to
55 cycles at a ramp rate of 1 Hz per minute
Vibrate the cells in the X-Y direction for three hours
Vibrate the cells in the Z direction for three hours
Measure Cap, ESR and DCL
Ramp oven down to –20°C and then hold for 15 min.
Ramp oven up to 70ºC and then hold for 15 min.
