How to Replace the Battery Pack on a Kohler Sensate Touchless Faucet
- Old cells leaked inside compartment
- Mixed old and new cells previously used
- Moisture in cabinet corroded contacts
Problem Description
Replace the below-deck battery pack on a Kohler Sensate faucet, restore reliable touchless response, and reset internal state so low-battery alerts clear after fresh cells are installed.
Symptoms
- Touchless sensor has become unreliable
- App shows critical battery status
- Faucet makes clicking noises
- Fresh premium batteries on hand
- Under-sink area accessible
- Flashlight available for cabinet work
Recognize these? Here's what usually causes it.
Common Causes
- Old cells leaked inside compartment
- Mixed old and new cells previously used
- Moisture in cabinet corroded contacts
- Battery pack connector loosened over time
- High-use kitchen drained cells faster
- Stale battery state cached in controller
Most fixes happen in the first 3 steps.
Never mix old and new batteries. Uneven discharge damages controller circuitry and causes repeated false low-battery alerts over time.

Step-by-Step Solution
Prepare Workspace
Clear the under-sink cabinet so you can access the Kohler control box without strain. Lay a towel to catch drips. Keep a flashlight nearby because the battery pack is often mounted behind supply lines where natural light does not reach.

$39.99Disconnect Battery Pack
Locate the cylindrical battery pack attached to the control box. Press the release tab and pull the connector straight out. Avoid twisting, which can stress the plug. Remove the pack fully so you can open it on a clean, flat surface.
Clean and Inspect Contacts
Open the pack, remove old batteries, and check for leakage or corrosion. Wipe contacts with a dry cloth. If you see heavy corrosion, replace the pack assembly rather than just the cells. Clean contacts improve conductivity and prevent false low-battery alerts.

$19.99Install Fresh Cells
Insert a full set of new premium batteries from the same brand and lot. Confirm polarity. Close the pack firmly. Reconnect the harness to the control box until it clicks. A secure connection is essential for stable sensor power during motion activation events.
Power Cycle and Verify
Unplug AC power briefly if your model has it, then reconnect to clear cached battery state. Refresh the Kohler app, confirm battery status reports healthy, and wave under the spout to test touchless response. Label the pack with today date for maintenance.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If drain continues after replacing batteries, check the event history — a stuck-open sensor or rapid polling loop burns through batteries in days.
Write the install date directly on the battery pack. Tracking usage time helps predict future replacements before the faucet becomes unreliable mid-task.
App battery indicators run 15–20% behind actual charge levels — by the time the low warning appears, the device has been struggling for days.
- Old cells leaked inside compartment
- Mixed old and new cells previously used
- Moisture in cabinet corroded contacts
- Battery pack connector loosened over time
- High-use kitchen drained cells faster
