*1. Value measured using an AC (Alternating Current) method in the fully charged state.
*2. Counts of charge and discharge repetition that maintains about 50% of the minimum guaranteed capacity
*3. A constant voltage charge is recommended, but due to a limit in the charge current, it is necessary to insert a resistor to regulate the
*4. D.O.D. : Depth of Discharge
TS lithium rechargeable batteries are high capacity 1.5V
type non-reflowable rechargeable batteries that provide
suffi cient discharge capacity with a charge voltage of less
than 2.0V, and are intended for support of recent low-
operating-voltage mobile devices.
