CR2032 3V Lithium Coin Battery

CR2032 3V Lithium Coin Battery provides replacement power for many bicycle computers, heart-rate straps, speed and cadence sensors, electronic shift controls, key fobs, scales, lights, and other compact electronics. Choose the available brand option before adding the battery to your cart. Each variant uses the standard CR2032 size and 3-volt lithium chemistry while retaining its own inventory record and product identification.

CR2032 describes a coin cell approximately 20 millimeters in diameter and 3.2 millimeters thick. Confirm that the device specifically calls for CR2032 before installation. A CR2025, CR2016, CR1632, or other similarly named battery may have a different thickness or diameter and should not be substituted unless the equipment manufacturer explicitly approves it. Check the old cell, device label, or owner’s manual when uncertain.

To replace the battery, open the compartment according to the device instructions and note which side faces upward. Handle the new cell by its edge, insert it with the polarity aligned correctly, and close the cover securely. Some sensors need to be paired again after battery replacement. If a device uses more than one cell, replace the full set and avoid mixing brands, chemistries, ages, or states of charge.

This listing is for one CR2032 battery in the selected brand. Coin batteries can cause severe injury if swallowed. Keep new and depleted cells away from children and pets, secure battery compartments completely, store unused batteries in their packaging, and recycle used lithium cells through an appropriate collection program.

Brand availability may vary, but both listed choices meet the standard CR2032 size designation.
