The minimum life expectancy of the energizer AAA batteries is one week. We used to be able to provide the Energizer Industrial which had a longer lifespan but unfortunately these are no longer available to us to order.
The battery indicator in the top-right of the pump will display the estimated life left, however the life left can be affected by the temperature. When leaving a heated house to outside and vice versa the battery indicator will change accordingly.
There are a few steps you can take to ensure that the battery lasts as long as possible:
· Ensure each battery placed into the device is new
· The backlight is not used in daytime
· Clear and respond to any alarms on the device. If left they can drain the battery
· Is the pump on vibrate mode? This will use more battery than the audio alerts
· Is the “remote” feature turned on? This feature will use more power as it keeps the pump awaiting an input form the remote using the radio frequency receivers.
· Uploading the pump to Carelink once a week will have a heavy impact on the battery life
