TS Lithium Rechargeable Battery <For Solar Watches> 1.5V Type
TS920E / TS621E (Under Development)
FEATURES
• Low-voltage rechargeable
• High capacity
• Long cycle life: at least 1000 cycles (20% D.O.D.)
• RoHS Compliant
TS lithium rechargeable batteries are high capacity 1.5V
type non-reflowable rechargeable batteries that provide
sufficient discharge capacity with a charge voltage of less
than 2.0V.

*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
charge current.
Please contact us for further details.
If a constant current charge is required, please contact us for more information.
*4. D.O.D. : Depth of Discharge
TS Lithium Rechargeable Batteries are not reflowable. Please mount them on PCB by hand soldering.
