A pocket scale that will not turn on may have depleted batteries, an incorrect battery connection or a charging problem. Before assuming the scale needs replacement, work through the power checks below.
Start with the correct battery type, battery placement and startup procedure. Calibration cannot restore power to a blank display.
This checklist applies to compact digital scales with replaceable batteries or rechargeable power. Follow the instructions for your exact model whenever they differ from general advice.
Quick Pocket Scale Power Checklist

The AWS product FAQ provides additional help with power problems and display messages.
1. Find the Exact Pocket Scale Model
Check the underside of the scale, its packaging or your purchase record for the model number.
This matters because similar-looking pocket scales can use different:
- Battery sizes
- Battery quantities
- Charging methods
- Power-button procedures
- Restart instructions
Find the matching guide in the AWS product manuals. Do not assume that instructions for another scale with the same capacity apply to yours.
2. Confirm the Startup Procedure
Place the scale on a stable surface with the platform empty. Open any cover that blocks access to the controls, then use the power button as instructed.
Some models use a brief press; others may require a different action. Avoid repeatedly pressing every button or trying undocumented button combinations.
Check for a Shipping Tab
If the scale is new, look for a clearly identified removable tab that isolates the batteries during storage.
Remove it only as directed. Do not pull unidentified strips, wires or internal parts.
Also confirm whether batteries need to be installed separately. A new product may include batteries in the package rather than inside the compartment.
3. Install Fresh Batteries of the Correct Type
If the scale uses replaceable batteries, replace the entire set with fresh, matching batteries of the specified type.
Battery Replacement Steps
- Disconnect external power, if applicable.
- Open the battery compartment as instructed.
- Remove the existing batteries.
- Check the required battery type.
- Install fresh batteries with the correct polarity.
- Close the compartment.
- Try the normal startup procedure.
Do not mix old and new batteries, brands or battery types. Energizer’s battery-care guidance recommends using the specified batteries and replacing them together. North America
Do Not Substitute Based on Size Alone
A battery that physically fits may have a different voltage or chemistry.
Use rechargeable replacements only if the scale manufacturer permits them. Do not install higher-voltage batteries or attempt to recharge disposable batteries.
4. Check Battery Polarity
Look carefully at the + and − markings inside the compartment.
Batteries installed next to one another may face opposite directions. For coin-cell models, follow the marked orientation rather than assuming which side faces outward.
Remove and reinstall any battery that is not seated correctly. Do not force it into position.
Checkpoint: If the scale turns on after correcting polarity, let its startup sequence finish before adding weight.
5. Inspect the Battery Contacts and Cover
With the batteries removed, visually inspect the accessible compartment.
Look for:
- Dust or loose debris
- White or colored residue
- Wet material
- Bent or broken contacts
- A damaged battery cover
- A battery that does not fit securely
For ordinary loose dirt, use only the cleaning method permitted by the manufacturer. Do not scrape contacts with metal tools or pour cleaning liquid into the compartment.
If You Find Leakage
Avoid touching leaked material with bare hands. Handling and cleanup depend on the battery chemistry and the condition of the scale.
Consult the battery and scale manufacturers before proceeding. Duracell’s battery information sheets provide chemistry-specific handling information for its products. Duracell
If It Works Only When You Press the Cover
A scale that turns on only when you squeeze the housing or press the battery cover may have a contact or compartment problem.
Do not wedge in paper, foil or other objects. Stop using the workaround and contact support.
6. Check Charging on Rechargeable Pocket Scales
For a rechargeable model, follow the specified charging procedure.
Confirm that:
- The cable is fully connected.
- The cable and supply are compatible with the scale.
- The charging source has power.
- Any expected charging indicator appears.
- You allow the charging time stated in the manual.
A plug fitting into the port does not prove that the charging setup is suitable. If the manufacturer permits it, test with another known-working compatible cable or supply.
Do not open the housing to disconnect or replace an internal battery unless the manufacturer provides a user-service procedure.
Stop charging if the device becomes unusually hot, swells, emits smoke or shows visible battery damage.
7. Consider Storage Conditions
A pocket scale stored for months may have exhausted or leaking batteries. A scale carried in a bag may also have had its power button pressed unintentionally.
Consider whether it was:
- Stored with batteries installed for a long period
- Left in a hot car
- Exposed to moisture
- Dropped or crushed
- Carried without protection for its buttons and platform
Let a cold scale return to its permitted operating conditions before use. If condensation is present, leave it disconnected and seek manufacturer guidance.
The AWS maintenance guide covers storage and care. Duracell’s battery-use guidance also explains why exhausted batteries and extreme temperatures can create problems. awscales.com
8. Use Only the Documented Restart Procedure
There is no universal reset sequence for every pocket scale.
Follow the manual if it describes removing user-replaceable batteries, disconnecting power or restarting the scale. Avoid undocumented button combinations.
If the power button feels stuck, loose or damaged, do not pry it out or force it. A mechanical fault may require service.
9. Separate a Power Failure From a Weighing Error
What appears on the screen changes the next step.
| Display behavior | What it tells you |
|---|---|
| Completely blank | Start with power and display checks |
| Brief flash, then blank | Check batteries and power connections |
| LO or a battery symbol | Follow the model’s low-power instructions |
| Error code | Record it and consult the manual |
| Stable zero | The scale is powered; check weighing operation |
| Incorrect weight | Investigate setup and measurement performance |
Once power is restored, verify normal operation before relying on readings.
Battery replacement does not automatically require calibration on every model. If the manual calls for it, or a suitable reference check indicates an error, follow the AWS guide on how to calibrate a digital scale.
10. Handle Removed Batteries Properly
Keep batteries secure while troubleshooting, especially button and coin cells. Refit the battery cover correctly before returning the scale to use.
The Consumer Product Safety Commission’s button-battery guidance explains why these batteries must be kept inaccessible to children. CPSC.gov
For disposal:
- Follow the EPA’s used household battery guidance and local requirements for replaceable batteries.
- Follow the EPA’s lithium-ion battery guidance for rechargeable batteries and devices. These should not go into household garbage or municipal recycling bins. US EPA
