It uses a user-replaceable 1000 mAh CR2477 Li/MnO2 coin cell battery (included), with a real-world lifespan of 12-24 months under typical conditions (broadcasting at 0.8 Hz and sampling at 0.4 Hz). Theoretical maximum is up to 10 years depending on firmware and usage. For extended temperature ranges (-40°C to +85°C), a CR2477T variant is recommended. No charging is required—simply replace the battery.
