* Nominal capacity indicates duration until the voltage drops down to 2.0V when discharged at a nominal discharge current at 20 deg. C.
** Dimensions and weight are for the battery itself, but may vary depending on the shape of terminals or other factors.

• How to select the protective resistance for the current control
The maximum charge current flows in the battery when charged at an end voltage of 2V. Therefore, the value of resistance is calculated using this
equation:
(R) >= ((Output Voltage of Voltage Regulator) - 2) / (Nominal Charge Current)
For example, the S-812C series, which has a maximum input voltage of 18V, or the S-817 series with a maximum input voltage of 10V (Seiko Instruments
Inc.) can be used as a voltage regulator.
Note 1: If the main power source voltage is stable, the charge voltage can be allotted from main power source divided by the combination of resistances.
Note 2: Because the battery height must be changed by the charge and discharge cycle, place a minimum of 1mm of space between the battery and
device or chassis.
The battery may be regulated by national or local regulation. Please follow the
instructions of proper regulation. As electric capacity is left in a discarded
battery and it comes into contact with other metals, it could lead to distortion,
leakage, overheating, or explosion, so make sure to cover the (+) and (-)
terminals with friction tape or some other insulator before disposal.

• Use within the rated temperature range of - 20 to + 60 deg C.
Otherwise, the battery's charge and discharge characteristics may be reduced.
• Never expose the battery to ultrasonic sound.
Exposing the battery to ultrasonic sound may cause short-circuiting because the inside material is broken into pieces, leading to distortion, leakage,
overheating, explosion, or fire.
• Never subject the battery to severe shock.
Dropping, throwing, or stomping on the battery may cause distortion, leakage, overheating, explosion, or fire.
• Never use or leave the battery in a hot place such as under the direct rays of the sun or in a car in hot weather.
If you do, this may cause distortion, leakage, overheating, explosion, or fire.
• Never allow the battery to come in contact with water.
If it does, this may cause the battery to rust or lead to distortion, leakage, overheating, explosion, or fire.
• Never store the battery in a hot and highly humid environment.
Doing so may cause the performance of the battery to deteriorate. In certain environments, this may lead to distortion, leakage, overheating, explosion, or
fire.
