Voltage drop using remote battery pack

How much voltage drop is there for the 30 feet of wire used for the remote battery pack for the five in one? The reason I ask is that I get one bar rather than two some of the time. I always received two bars when the batteries were in the five in one. What battery best over comes that?

Hello William,

The battery extender should not affect the signal strength of the sensor.  Are you seeing the signal drop on the display or on Acu-Link.com?  If you are seeing the drop on the display please follow the directions listed below.  I have also added our battery recommendations.  If the issue persists please contact us back here or AcuRite Customer Support at 877-221-1252.  Thank you and have a great day!

  • 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.
Perform a hard reset:

  1. Bring both the sensor and display unit indoors side by side.
  2. Remove batteries from the sensor.
  3. Remove batteries from the display unit and unplug the AC adapter (if applicable).
  4. Wait 5 minute to ensure any remaining battery power is discharged from both units. 
  5. Make sure the A-B-C ID code switch on both units match. 
    *Sometimes changing to a different ID code can help.
  6. Reinstall batteries in outdoor sensor first.
  7. Reinstall batteries in display unit second.
  8. Let the units sit within a couple feet of each other for a few minutes to ensure a wireless signal is received. 
    * The display should receive the signal within several minutes. 
  9. After a connection has been established you may place the sensor outdoors.
    *If the signal connection fails after the units are separated try a new or different location for the display unit, the sensor or both.

Some folks have home-brewed these before.  Signal loss has never been mentioned as a side-effect.

I've no idea what the voltage drop would be.  It would depend on the resistance  of the wire they used.  I suspect they considered this and sized the wire appropriately.

If you are concerned about the voltage drop, lithiums should have a bit of an advantage.

Thank you Rachael for your answer regarding that the design should create little problem.  And, thank you George for confirming that the lithium type battery might make the difference if it would remain consistently at two or more signals. I am now using Duracell Copper top batteries which have lasted at least several months with no drop since initial installation.  I haven't noticed a complete drop to no bars with the new Acurite remote battery pack yet; however, it is just that I would not like my five in one to go off line to Weather Underground for any length of time.   I will probably  go with either Energizer or Duracell lithium batteries in the future,

Hello William,

We only recommend using Lithium batteries when temperatures are -4 and below.  Duracell does not currently make a Lithium battery. We do recommend something like Energizer Advanced Lithium when/if needed.  You need at least one bar to stream your sensor to Acu-Link.com. As long as your sensor is streaming to Acu-Link it should also transmit to Weather Underground. Something that improves reception would be to pull the bridge out as far from the router as you possibly can towards the direction of the sensor.  The battery pack should not affect the signal strength, but if you are concerned you can also look into a signal extender.  I have added a link below for your convenience.  Have a great day!
