How long does the Sensedge Go battery last?

The Sensedge Go is a wireless, battery-powered device, with up to 8 years of battery life under the default setting.

Battery life depends on three things: the sampling configuration you choose, the operating hours you set, and which Sensedge Go SKU you have (what parameters you measure).

Battery life by configuration

Configuration	Sample intervals	Expected battery life
Default (factory setting)	Operating hours: PM2.5 every 10 min; all other analytes every 1 min Off-hours: PM2.5 every 60 min; all other analytes every 5-15 min based on battery level	SE-300A: 4.42 years SE-300W: 3.45 years SE-300L: 8.33 years
Adaptive Sampling™	Operating hours: PM2.5 every 10-60 min, set algorithmically; all other analytes every 1 min Off-hours: PM2.5 every 60 min; all other analytes every 5-15 min based on battery level	Over 10 years*
Custom	Choose 1, 2, 5, 10, 15, 20, 30, or 60 minutes, or a 24-hour interval, for each analyte. You can also set a custom off-hours time frame.	Depends on the configuration

Expected battery life

Default (factory setting)

Operating hours: PM2.5 every 10 min; all other analytes every 1 min

Off-hours: PM2.5 every 60 min; all other analytes every 5-15 min based on battery level

SE-300A: 4.42 years

SE-300W: 3.45 years

SE-300L: 8.33 years

Adaptive Sampling™

Operating hours: PM2.5 every 10-60 min, set algorithmically; all other analytes every 1 min

Off-hours: PM2.5 every 60 min; all other analytes every 5-15 min based on battery level

Over 10 years*

Custom

Choose 1, 2, 5, 10, 15, 20, 30, or 60 minutes, or a 24-hour interval, for each analyte. You can also set a custom off-hours time frame.

Depends on the configuration

*Adaptive Sampling™ requires 10 or more devices in a building to achieve this battery life.

How operating hours affect battery life

The estimates above assume operating hours of 9am-5pm, Monday to Friday. Off-hours are the nights and weekends outside that window.

In practice, operating hours are set per building by the user, based on that building's actual occupancy schedule. Longer operating hours reduce battery life, because the device spends more time on the higher-frequency sampling schedule.

If your building runs extended hours - for example 7am-9pm, seven days a week - expect battery life below the figures in the table.

Which configuration should I use?

For most deployments, the default configuration is sufficient and it meets WELL’s requirements on sampling intervals. You don’t have to make any changes.

Choose Adaptive Sampling™ if you have 10 or more devices in the building and want to maximise battery life. The algorithm adjusts the PM2.5 sample interval during operating hours based on conditions, rather than holding it at a fixed 10 minutes. Note that this does not comply with WELL’s sampling interval requirements.
