Use low-battery reporting

Enable alerts where available.

Keep a small inventory

Know which devices use which battery type.

Radio conditions affect life

Poor connectivity can cause some devices to communicate more often or less efficiently.

Replace safely and correctly

Use the battery chemistry, orientation and replacement method specified by the manufacturer.

Keep in mind. Compatibility is not permanent. Confirm the current manufacturer, platform and certification information before purchasing, resetting or migrating a device.
