Sensor Battery Life and Replacement
Homeowner Summary
Most Shipshape sensors are battery-powered and run for roughly two to five years before the battery needs replacing, depending on the device and how often it reports. Shipshape watches battery level for you and sends a low-battery alert well before a sensor goes dark, so a dead battery rarely catches you by surprise.
If a battery drains much faster than expected, it's usually one of a few causes — heavy sensor activity, a weak connection to the gateway, a battery installed backwards, or simply a low-quality battery. This article explains why batteries drain, how to replace them, and when faster-than-normal drain points to something worth fixing.
Why a Battery Drains Faster Than Expected
1. Frequent triggering or sensor activity
- A sensor that's triggered repeatedly (for example, a leak sensor placed where it keeps getting wet, or a door sensor on a frequently used door) stays active longer and uses more power.
- On water-leak detectors, the small internal sensor button being pressed or held for an extended period keeps the sensor engaged and accelerates drain.
2. Weak connection or signal strength
- If a sensor struggles to hold a steady connection — because it's far from the gateway or there's interference — it burns extra power retrying.
- A sensor far from your gateway or a range extender will have shorter battery life. Moving it closer, or adding a range extender, improves both connection and battery life.
3. Battery installation or quality
- Make sure the battery is seated correctly: the + (positive) side must match the + symbol in the compartment. A reversed battery won't power the device and can cause odd behavior.
- Battery quality varies between manufacturers. Use a reputable name-brand battery of the exact type specified for your device.
4. Natural wear and environment
- Battery lifespan varies with temperature and humidity. A sensor in a hot attic, an unconditioned crawl space, or a high-humidity area will see shorter battery life than one in conditioned living space.
Replacing a Battery
- Wait for the low-battery alert in the Shipshape app, or check the device's battery level on its detail screen.
- Confirm the battery type your device uses (printed inside the compartment or in the device's help article — common types are CR123A, CR2477, and CR2032).
- Open the device, remove the old battery, and insert the new one with the + side matching the + symbol.
- Close the device. It should report a healthy battery level to the app within a few minutes. If it doesn't, see Water Leak Sensor Offline or Low Battery.
Replace batteries with the device near the gateway when possible, so it re-establishes a strong connection right away.
When to Call a Professional
A fresh, correctly installed battery that drains again within weeks usually points to a hardware fault or a placement/connection problem rather than the battery itself. Contact Shipshape support or your installer if a device repeatedly drains new batteries, or if it won't come back online after a replacement.
Shipshape Integration
Shipshape monitors battery level on every battery-powered sensor and raises a low-battery alert before the sensor stops reporting — so you replace batteries on your schedule, not after a sensor has already gone silent. Repeated low-battery alerts on the same device, especially soon after a replacement, are a signal worth investigating with support.
