Choosing batteries and accessories
Match batteries to each device’s listed type and check charging method, runtime, and compatibility for rechargeable field gear.
Check the device label or manual for the exact battery code, chemistry, voltage, and orientation. Similar size alone does not confirm compatibility. Use another cell only when the device maker lists it as an equivalent.
The short answer
Choose the battery type, chemistry, and voltage specified by the device maker.
Battery type and chemistry
Match the cell code and chemistry named by the device maker. A cell can fit the compartment and still be the wrong type. Energizer lists the specifications for its CR2032 coin cell.
Voltage and device rating
Use the voltage specified for the device. Do not choose a cell by fit alone.
Specific spare type
Before a trip, compare each device’s battery code and orientation with its label or manual, then pack the matching spare.
Radios and rechargeable power
For radios and rechargeable field gear, compare battery type, charging method, runtime, and compatibility with the device. Point Blank Archery’s Radios & Power collection groups communication and portable power items. Check the device manual for the exact power requirements.
Storage and recycling
Follow the cell maker’s storage directions. Do not let children play with or handle button or coin batteries. CPSC says a swallowed button cell can burn a child’s throat or esophagus in as little as two hours. (CPSC button and coin battery safety) EPA says to recycle lithium and button or coin cells through specialized collection, not household trash or municipal recycling. (EPA battery recycling guidance)

Before you buy
If a device label is missing or hard to read, check its manual before ordering a replacement cell.

What battery should I carry?
Match the device maker’s listed code, chemistry, voltage, and orientation. Similar size alone does not confirm compatibility.
How do I handle used button cells?
Keep button cells away from children. Follow local collection guidance and use a battery recycler or hazardous-waste collection program rather than household trash or curbside recycling.
How do I compare radios and rechargeable power?
Compare the device’s battery type, charging method, runtime, and compatibility. Check the exact device manual before choosing a power source or charger.
