Description
The Panasonic ML-2020/F1AN 3V Rechargeable Lithium Battery provides dependable rechargeable backup power for compatible electronic equipment requiring an ML2020 lithium-manganese coin cell with F1AN solder-tab terminals. Manufactured under the Panasonic brand, this battery belongs to Panasonic's ML rechargeable lithium battery series and features manganese lithium rechargeable (Panasonic ML series) chemistry, a nominal voltage of 3.0 volts, and a capacity of 45 mAh. Its compact coin-cell design is particularly suitable for compatible memory backup circuits, real-time clock (RTC) backup systems, industrial electronic assemblies, communication equipment, and other low-current electronic applications designed for rechargeable ML2020 batteries.
Designed in the standard ML2020 coin-cell format, the Panasonic ML-2020/F1AN battery measures 20.0 × 2.0 mm (0.79 × 0.079 in), diameter × height, coin cell without tabs. The battery weighs 2.2 g (0.078 oz). This F1AN version features 2 tabs (F1AN) arranged for compatible surface-mount electronic assemblies, rather than a conventional loose coin-cell holder. The battery uses manganese lithium rechargeable (Panasonic ML series) chemistry and is designed for compatible charging circuits operating at 2.8–3.2 V constant-voltage. Its low-current characteristics make it suitable for maintaining memory and real-time clock functions in properly designed electronic systems.
The Panasonic ML-2020/F1AN is a rechargeable lithium coin-cell battery intended for equipment specifically designed to charge and operate an ML2020 battery with matching F1AN terminal configuration. It must not be substituted with a non-rechargeable CR2020 or CR2032 battery in a charging circuit, and it must not be assumed interchangeable with rechargeable VL2020 or LIR2020 batteries because their chemistry, charging requirements, and electrical characteristics can differ. The F1AN solder-tab configuration must also match the equipment's circuit-board mounting layout and polarity. Always verify the original battery part number, charging voltage, nominal voltage, physical dimensions, terminal arrangement, and equipment manufacturer's approved replacement specifications before installation. Each purchase includes one Panasonic ML-2020/F1AN 3V Rechargeable Lithium Battery.
