How long should your Wellntel battery last?

Wellntel Home Static can be powered with either a 9V non-rechargeable lithium-ion battery, an AC adapter, or a Solar Power Kit.

If you must measure pump duty and/or take water level readings during pumping, you should choose a Wellntel +Pump Kit, which can be powered by either an AC adapter, or a Solar Power Kit, but not by battery, since battery life will be shortened by readings taken during pumping and it’s much cheaper to go with line or solar power in the long run.

If you own or want a Home Static system, and choose the battery option, you should be aware that battery life is variable and depends on many operational factors. Out of the box, your Wellntel’s default settings is a timed reading taken every four hours and the system is designed with ample radio transmission for most most yards and some small farms. In this duty, the battery may last up to ten months. Factors that will shorten battery life include: a shorter timed interval, readings taken during pumping events, long periods of pumping, a long distance or many obstructions (like Stucco,  metal buildings or hillsides) between the sensor and gateway, or very wide and frequent temperature swings.

If you have a batter-powered Wellntel already, and are measuring pumping, we suggest that you upgrade to either an AC adapter or Solar Power Kit the next time your battery runs out. Either will pay back quickly.

You may be able to improve battery life by improving radio signal strength by “lifting” one or both of your antennae using our antenna extension and mounts. A Wellntel technician can help you check signal strength and will help you determine is this is a viable option.

Finally, for some applications, it may not be necessary to measure every event. Battery life can be maximized, to some degree, with settings changes.

  • At your request, a qualified technician can change the system settings to only measure one pumping event in a day. In this mode, the customer will have one recovery event per day for reference, but will not receive pumping duty totals or be able to set pump duty alerts. This setting dramatically decreases the load on battery and extends its life in a pump cycling application.
  • At your request, a qualified technician can change the system settings to limit the number of readings taken during a pumping event. This also saves battery power, but at a lower data resolution for pumping data, and not as dramatically as option one.
