Checking the recharging function
A conventional method of checking the recharging function is to check the difference of the rechargeable
battery voltage between before and after a recharge.
<Checking procedure>
1) Apply the probes of the tester as shown in the illustration to measure the voltage of the rechargeable
battery before recharge.
2) Place the watch at a distance of 5cm under a fluorescent light of 15 to 20 watts, and charge it for 30 minutes.
Remarks:
•
Be sure to use a fluorescent light to charge the watch, as light
sources generating heat may cause damage to the watch. To
charge the watch efficiently, place it under the center of the
fluorescent tube.
•
While charging the watch, make sure that the watch
temperature does not exceed 50
°
C.
3) After recharging for 30 minutes, apply the probes of the
tester in the same manner as in step 1) above, and
measure the rechargeable battery voltage while keeping
the watch exposed to the light.
4) Refer to the table below to determine whether the recharging function is normal or not.
Voltage before recharge
Criteria for recharging quality
1.01 ~ 1.30V
The battery is normal if the rechargeable battery voltage has
increased more than 0.04V after recharge.
[Guideline for the quality of the recharging function]
* The above criteria are applicable only when the rechargeable battery voltage before recharge is within
the range of 0.5V and 1.3V.
0.5 ~ 1.00V
The battery is normal if the rechargeable battery voltage
obtained after recharge is more than 1.2V.
