Energizer Series CR Button Battery, 20mm Diameter, 3V Nominal Voltage - 7638900083026


This button battery is a 3V lithium coin cell designed to provide long-term power for low-drain electronics. It uses a lithium/manganese dioxide chemistry and is intended for applications requiring a compact, low-profile energy source with very low self-discharge across a wide temperature range.

Features and Benefits:


• 155mAh capacity for extended service life under light loads
• 3.0V nominal voltage for stable device operation
• Flat termination reduces contact resistance in holders
• Low self-discharge of ∼1%/year for long storage life
• Operates between -30°C and 60°C for varied environments

Applications


• Suitable for remote key fob power replacement
• Used with wrist devices requiring thin-profile cells
• Ideal for small sensors with intermittent pulses
• Can be used for memory backup in low-power electronics

How does the cell behave under continuous background drain?


At a 15kΩ continuous load the cell yields about 835 hours of service with a typical drain of 0.186mA at 2.9V.

What Pulse performance can be expected for periodic transmissions?


Under a Pulse schedule of 2s Pulses 12 times per day, a 400Ω Pulse produces approximately 6.8mA at 2.7V during bursts.

What limits exist for reverse charging?


The maximum permissible reverse charge is about 1μA, indicating very low tolerance for being charged in reverse.

What are the energy density and lithium content figures?


Energy density is roughly 176mW·hr/g and 616mW·hr/cc with typical lithium content of 0.078g.

How should compartments be designed for safety regarding child access?


Design should require either a tool to open the compartment or two independent simultaneous movements to release the cover to reduce removal risk.
