4. 0 V Battery Charge Starting Charger Voltage (Product with 0 V Battery Charge Function), 0 V

Battery Charge Inhibition Battery Voltage (Product with 0 V Battery Charge Inhibition Function)

(Test circuit 4)

Ether the 0 V battery charge starting charger voltage or the 0 V battery charge inhibition battery voltage is

applied to each product according to the 0 V battery charging function.

Function)

The starting condition is V1

= V2 = V3 = V4 = 0 V for a product in which 0 V battery charging is

Inhibition Function)

The starting condition is V1

= V2 = V3 = V4 = V
