Understanding How Your SimpleHuman Trash Can Works
Before diving into the battery replacement process, it’s essential to understand how your SimpleHuman trash can functions. Most SimpleHuman trash cans in the sensor-activated category use a motion-detection system powered by batteries. When your hand or an object comes within range (usually 6 to 12 inches), infrared sensors detect the movement and trigger the motorized lid to open silently and smoothly.
The Role of Batteries in Sensor Operation
The batteries serve two main purposes:
- Powering the motion sensors for detection accuracy
- Operating the motor that lifts and closes the lid
Low or dead batteries result in delayed responses, incomplete lid opening, or no response at all. Thus, consistently replacing batteries as needed ensures the sensor remains responsive and the mechanism operates flawlessly.
Different Types of SimpleHuman Trash Cans and Their Power Sources
Not all SimpleHuman models use the same type of battery or power configuration. Here’s a quick breakdown:
| Model Type | Battery Type | Number of Batteries | Typical Battery Life |
|---|---|---|---|
| Sensor Can – Basic Models | D-cell alkaline | 4 D-cells | 6–12 months |
| Sensor Can – Advanced Models (e.g., 80 Series) | AA rechargeable batteries | 4 AA batteries | Up to 1 year (with charging) |
| Recycler & Step Cans (non-sensor) | Manual operation (no batteries) | N/A | Indefinite |
Pro Tip: Always verify your specific model number (found on the bottom or at the rear of the can) before purchasing replacement batteries. Using incorrect batteries may damage the electronics or void your warranty.
When Should You Change the Batteries?
Recognizing early signs of battery depletion helps prevent sudden malfunctions. Here are several indicators that the batteries in your SimpleHuman trash can may need replacement:
1. Slow or Incomplete Lid Movement
If the lid opens sluggishly, doesn’t open fully, or takes longer than usual to respond, it’s typically a sign of low power.
2. No Response from the Sensor
When waving your hand in front of the can elicits no reaction, the sensor may not have enough power to function effectively.
3. Intermittent Operation
Sometimes the lid opens and other times it doesn’t. This inconsistency suggests unreliable power delivery from the batteries.
4. Flashing Indicator Lights (on Select Models)
Some SimpleHuman models feature LED status indicators. A blinking red or yellow light usually indicates low battery levels.
5. Unusual Noises During Operation
Weak batteries may cause the motor to strain, producing grinding or stuttering sounds.
Note: If replacing the batteries doesn’t resolve these issues, the problem may be with the sensor, motor, or mechanical components — not necessarily the power source.
Tools and Materials You’ll Need
The battery change process is straightforward and requires minimal tools. Here’s what you should prepare:
- Fresh batteries (correct type for your model)
- Small flashlight (optional, for visibility in low-light areas)
- Soft cloth (to keep the battery compartment clean)
For most users, it’s recommended to use high-quality alkaline batteries. Avoid using old or recharged batteries unless your model specifically supports rechargeable ones.
Alkaline vs. Rechargeable Batteries
SimpleHuman designs their trash cans with battery efficiency in mind. While standard D-cell and AA alkaline batteries work well, some users opt for rechargeable NiMH (Nickel-Metal Hydride) batteries, particularly in high-usage households.
| Battery Type | Pros | Cons | Cost Over Time |
|---|---|---|---|
| Alkaline | Long shelf life, high power output, widely available | Not rechargeable, less eco-friendly | Higher long-term cost |
| Rechargeable (NiMH) | Eco-friendly, cost-effective, long-term savings | Lower voltage, shorter lifespan per charge | Lower cost over 2+ years |
While rechargeable batteries are sustainable, ensure they are compatible with your model. Some automatic sensors may not respond reliably to lower voltages.

– Secure the screws in a safe place during replacement.
Warning: Never force open the compartment. If it doesn’t budge, double-check for hidden latches or screws.
Step 5: Remove the Old Batteries
Once the compartment is open, carefully remove each battery.
- Note the orientation of each battery (positive (+) and negative (–) ends).
- Check for signs of leakage, corrosion, or swelling.
- If you see corrosion, clean the contacts with a cotton swab dipped in white vinegar or rubbing alcohol. Let it dry completely before inserting new batteries.
Dispose of old batteries properly at a recycling center or electronic waste facility. Never throw them in regular trash due to environmental and fire hazards.
Step 6: Insert the New Batteries
Follow the polarity diagram inside the battery compartment. It shows the correct direction for inserting each battery.
For models requiring D-cells:
– Insert each battery firmly, ensuring the positive end aligns with the spring or contact marked (+).
– Most models hold four D-cell batteries in a side-by-side or stacked configuration.
For models with AA batteries, typically used in rechargeable units:

Changing the batteries in a SimpleHuman trash can typically requires very few tools, as most models are designed for easy maintenance. All you need is a fresh set of AA or D batteries, depending on your specific model, and possibly a flathead screwdriver if your trash can has a secured battery compartment. Most models use either four AA or four D batteries to power the sensor and automatic lid mechanism.
Before starting, make sure to consult your user manual or check the manufacturer’s website to confirm the type of batteries your model uses. While the manual may recommend alkaline batteries for longer life, avoid using rechargeable batteries as they often do not provide sufficient voltage. The design of the SimpleHuman trash can allows for tool-free access in many cases, but if there are screws, a small screwdriver will help without damaging the plastic casing.
How do I locate the battery compartment on my SimpleHuman trash can?
The battery compartment on a SimpleHuman trash can is typically located on the bottom or side of the base unit, depending on the model. For most automatic sensor models, you’ll find a rectangular panel with a “Battery” label or symbol underneath the can or near the back of the base. Some designs may place the compartment behind a removable plastic cover on the side to protect it from spills and moisture.
To access it, gently turn the trash can upside down on a soft surface to avoid scratching the finish. Look for screws or a sliding latch securing the cover. If there are screws, carefully remove them using a screwdriver. For latch-style compartments, slide the tab to release the panel. Take care not to force anything, as this could damage the housing. Once opened, you’ll see the battery tray where the old batteries are seated.
Can I change the batteries without turning off the trash can?
It is strongly recommended to turn off your SimpleHuman trash can before changing the batteries, if your model includes an on/off switch. This prevents accidental activation of the lid during the process, which could pinch fingers or malfunction due to fluctuating power. Most models feature a small power switch near the sensor or inside the battery compartment—flip it to the “Off” position before starting.
Even if your model doesn’t have a switch, removing the old batteries effectively powers down the unit. However, handling the trash can while it’s operational could cause erratic behavior, especially if the battery voltage is low. Turning it off (or ensuring it’s off by removing batteries) ensures a safe and smooth battery replacement and helps preserve the sensor’s integrity over time.

Avoid using lithium or rechargeable batteries, as they may not deliver the correct voltage range and could lead to performance issues.
Using the correct battery type also helps extend the life of your trash can’s electronic components. Rechargeable batteries tend to have a lower voltage (1.2V vs. 1.5V for alkalines), which may cause the sensor to respond slowly or fail to activate. Additionally, leaking or low-quality batteries can damage the battery contacts or internal circuitry. Always replace all batteries at the same time to maintain balanced power distribution.
How often should I replace the batteries in my SimpleHuman trash can?
On average, you should replace the batteries in your SimpleHuman trash can every 6 to 12 months, depending on usage. A household with frequent use—such as multiple lid openings per day—may need to replace batteries closer to the 6-month mark. Models with LED lights or voice activation may consume power more quickly and require more frequent changes.
Signs that it’s time to change the batteries include a slow or unresponsive sensor, a lid that doesn’t open fully, or intermittent operation. Some models may also have a low-battery indicator light that blinks when power is running low. To avoid disruption, consider replacing the batteries as a preventive measure once a year, especially if you notice any decline in performance before complete failure.
What should I do if the lid does not work after replacing the batteries?
If the lid of your SimpleHuman trash can does not work after installing new batteries, first double-check that the batteries are inserted correctly according to the polarity markings (+/-) inside the tray. Incorrect placement is a common cause of malfunction. Also, ensure that all batteries are fresh and from the same brand to avoid voltage inconsistencies.
Next, inspect the battery contacts for corrosion, dirt, or damage. Clean the contacts gently with a dry cloth or cotton swab. Reset the trash can by removing the batteries for 30 seconds and then reinserting them. If the issue persists, verify that the power switch (if present) is set to “On” and that the trash can is on a level surface. If none of these steps restore function, contact SimpleHuman customer support for troubleshooting assistance.
Are there any safety tips to follow when changing batteries?
Always handle battery replacement in a dry environment and ensure your hands are clean and dry to prevent moisture from entering the battery compartment.
