The cyclic life of a battery can be estimated by measuring the duration time of one cycle. For
this test, one cycle consists of a discharge through a 16 ohm resistor to the end voltage of 10.5
V per battery and a charge of six hours with a charger that uses a charging voltage of 14.70 V
(+0.2 V) and an initial maximum current of 0.92 A. The ambient temperature should be 25°C
(+2°C) for the test. Under these conditions, the cycle life shall be more than 150 cycles to the
end of use when the duration time in discharging is 60 minutes.
The over-discharge recovery of the batteries can be estimated by using the following test
procedure at an ambient temperature of 25°C (+2°C). Connect the battery to a 16 ohm
resistor and discharge the battery for 24 hours. Open the circuit and stand the battery for one
month. Charge the battery for 24 hours with the specified charger (see Cycle Life above).
Remove the battery from the charger and let it stand for one hour. Now discharge the battery
at 0.75 A to the end voltage of 10.5 V. The duration time for the discharging should be more
than 90 minutes. If the batteries discharge much more quickly than expected, the batteries
have exceeded their useful life and should be replaced.
