Energizer Series CR Button Battery, 20mm Diameter, 3V Nominal Voltage - 7638900248333

This button cell is a 3V lithium coin cell intended to power small electronic devices where compact, long-life energy is required. It uses a lithium/manganese dioxide chemical system and is supplied as a two-cell pack for applications that demand consistent low to moderate continuous or Pulse current over extended storage and operating temperatures.

Features and Benefits:

• 155mAh capacity delivers prolonged service for low-drain devices
• Flat termination simplifies secure mounting and contact stability
• Low self-discharge of ∼1%/year supports long shelf life
• Operates from -30°C to 60°C for wide environmental use
• 1μA maximum reverse charge minimises risk from charging currents

Applications

• Suitable for key fob remote devices requiring Compact cells
• Ideal for watches and timing instruments with low drain
• Used with small medical sensors needing long storage life
• Can be used for calculators and LED indicators with Pulse loads

What continuous drain behaviour can I expect at room temperature?

A continuous 15kΩ load draws about 0.186mA producing roughly 835 hours of service until 2.0V cut-off.

How does the cell perform under periodic Pulse loads?

Pulse testing with 2s Pulses 12 times/day shows capability to handle higher instantaneous currents such as 6.8mA at 2.7V with a 400Ω Pulse load.

What are the physical attributes relevant to device design?

The cell has a diameter of 20mm and a height of 2.5mm and weighs approximately 2.6g, with a flat TOP termination suited to surface contact.

What safety considerations should be applied for user access?

Compartments should require a tool or two independent motions to open and children must be prevented from accessing cells due to ingestion hazards.

How efficient is the energy storage relative to mass and volume?

Energy density is about 176mWh/g and 616mWh/cc, with typical lithium content near 0.078g.
