ML1220 Rechargable 3V Lith-Ion

Lithium Rechargeable 3 VOLT Battery with Tabs

DESCRIPTION

The ML1220 is a 3V rechargeable lithium manganese dioxide button cell battery, commonly used for CMOS/BIOS memory backup in laptops (e.g., Dell, Toshiba) and other small electronics.

• Specifications:
  • Capacity: 17mAh
  • Diameter: 12.5mm
  • Height: 2.0mm
  • Often comes with solder tabs

Features

This versatile battery is ideal for a wide range of applications, including:

• Computer motherboards
• Remote controls
• Active RFID products
• 3D glasses
• Cameras
• Watches
• POS machines
• Electronic toys
• Shoe lights
• LED lights
• Electronic flash products
• Other electronic devices

Performance Highlights

1. High Working Voltage

• The working voltage can reach up to 2.8V.
• When charged at a constant voltage of 3.0 to 3.25V until full capacity is reached and discharged at a standard current of 0.1mA to 10% of the nominal capacity (DOD10%), the discharge voltage is close to 3V, higher than that of Japanese brand products.
• When discharged at 2mA for 10%, the discharge voltage remains higher than 2.7V.

2. Excellent Heavy-Load Capacity

• Under full charging conditions, discharging 10% of the capacity at a current of 2.0mA can achieve a cycle life approaching 180 times.
• In the first 150 cycles, the terminal voltage after 10% deep discharge stays above 2.8V.
• Under the same test conditions, the 10% charge and discharge cycle life of the same model battery of Japanese brands is comparable, but their terminal voltage is always lower than 2.4V.

3. Exceptional Performance in Extreme Applications

• Even when discharged at 8mA in the fully charged state, the battery can still achieve a 10% deep discharge application of the nominal capacity.

This battery is designed to deliver superior performance, reliability, and durability, making it a trusted choice for various electronic devices and demanding applications.
