Battery Life

RX2103 Battery Life:

Battery life with daily connections:

• RX2103: 1 year with 2 minute logging

Battery life with hourly connections and 1 minute logging:

• RX2103: 2 months

Note: Deployments in areas with weak cellular strength could reduce battery life.

RX2104 Battery Life:

Typical 3–5 years when operated in the temperature range -20° to 40°C (-4° to 104°F); operation outside this range will reduce the battery service life.

Maximum connection rates with built-in solar panel, in full sun:

• 10 minute connections year round for latitudes less than ±40°
• 10 minute connections through three seasons in other regions, reduced to 30 minute connections in winter

Maximum connection rates with external 5W or 15W solar panels:

• 10 minute connections year round, in full sun
• Connection rate with external solar panels may be less if deployed in partial sun

Battery life without solar recharging, with hourly connections and
1 minute logging:

• RX2104: 2 months
