Lithiums in 5-in-1 Sensor Last a LONG Time (6 Years!)

It's been 2 years since I installed my 5-in-1 sensor. I used lithium batteries, Energizer Ultimate AA, rated at 3 amp-hours. Not knowing how much power the 5-in-1 was drawing from these batteries I decided to play it safe and replace them now.

The measured voltage on each of the 4 AA cells that I removed were 1.7v. That's high for a battery that I expected to be about gone. So I connected the 4 cells to a load and a voltage logger to see just how much capacity was left in them. Would you believe 2.175 amp-hours!!?? So in 2 years they have lost less than a third of their capacity. A fresh set should therefore go for 6 years. Not bad.

If only my 09150 bridge would go 1% that distance without losing its connection to WU.

Hello Wingsy,

Our weather stations are specifically designed to not be high draining units. We do recommend the battery guidelines below. We typically say you should get 12 months out of the batteries depending on the name brand.  We do recommend using Alkaline batteries, unless you are in a location where you will get temperatures below -4 for a long period of time. I have posted the guidelines below:

  • Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.
  • Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.
  • Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.
  • Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.
  • Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.
  • Mixing different battery types (brands, old/new, etc.) is not recommended.

Rayovac Fusions are the only one's I've had last more than a month lately. I've tried Energiser, and Duracells, those run down faster for some reason I have yet to understand.

Hello Jon008,

How long have you had your sensor?  The batteries in a 5in1 sensor should last anywhere from 12-24months.  We do not recommend using Rayovac Fusions.  We recommend standard Duracell, Rayovac, Energizer, or Kirkland batteries.  Thank you.

What is wrong with Fusions? They are Alkaline, and work perfectly for me. They also do not die after 1 month in the sensor. The humidity sensor in mine is failing, so I believe this is the fault in my unit. It will be 3 yrs old this coming January.

Hello Jon008,
We do not recommend using Fusion batteries within our units. As we have seen our users experience issue before when using these batteries. We would recommend changing to something such as Duracell Coppertop, Energizer alkaline, Or Kirkland's. We want to make sure we are exhausting all troubleshooting. This way we can determine what is causing the issue that you are experiencing. Thank you.

Thank you. I am not having any issues at this time. I have your battery pack extension and it works very nicely to keep from having to take down the sensor from it's home 30 Ft AGL.
