Energizer Series CR Button Battery, 3V Nominal Voltage, 235mAh Capacity - 7638900083040


This button battery is a 3V lithium coin cell designed to provide compact, low-drain power for small electronic devices. It uses a lithium/manganese dioxide chemistry that offers long shelf life and stable voltage output across a wide temperature range, making it suitable for devices requiring reliable coin-cell power in everyday and industrial settings.

Features and Benefits:


• 235mAh typical capacity delivers extended service life
• Flat termination enables secure, low-profile contact
• Self-discharge ∼1%/year reduces replacement frequency
• Operates between -30°C and 60°C for varied environments
• Continuous background drain 0.19mA at 2.9V for standby loads

Applications


• Suitable for key fobs and remote controls requiring steady output
• Ideal for small medical sensors with low continuous drain
• Used with memory backup circuits needing low self-discharge
• Can be used for fitness trackers and wearable sensors
• Appropriate for electronic scales and small measurement devices

How does it behave under frequent short pulses?


Short repeated Pulses draw higher instantaneous current, a 400Ω Pulse yields approximately 6.8mA at 2.7V for 2-second bursts repeated multiple times per day.

What is the maximum allowable reverse current during accidental charging?


Reverse charging is limited to a maximum of 1μA Peak to prevent hazardous conditions.

How much lithium is contained in the cell by mass?


The typical lithium content is 0.109 g within each coin cell.

What is the typical energy density by volume?


The cell has about 653 mW·h/cc energy density, reflecting Compact energy storage.

At what voltage is the cell considered depleted for load cut-off?


The usable cut-off voltage under typical conditions is 2.0V.
