How long do the batteries last?

With general use (twice daily readings, with average alert triggers), we would expect the batteries to last 2-3 years. For hourly readings, we would expect to see battery life of around 12-18 months.

That being said, battery life depends on many factors:

- WiFi units tend to last longer than LTE units because the LTE units use more power connecting to the Telstra network to send readings.

- If the readings are more frequent, the batteries won’t last as long.

- Weather can play a part too, battery life can be degraded in hot weather.

- And if alerts are being triggered often, those batteries will run down faster than a sensor that doesn’t have alerts set or not as frequently triggered.

If the abnormal usage alert has been enabled, it will automatically change to take a reading every hour (irrespective of what setting you have put in for reading frequency). This is so it is able to compare successive hourly readings to determine if the threshold has been broken.

If just the low and/or high alerts have been enabled, it will send an alert when it next takes a reading that breaks that threshold - in this case, customers should look to increase thereading frequency to shorten the gap between readings so they are less exposed to loss of water due to breaks, accidents etc.

If the sensor is on a critical tank, customers should consider scheduling a battery replacement into their maintenance cycle (eg every year), quite a few of our customers already do this as it provides peace of mind and means they're being proactive rather than reactive.
