The Homedics SC 380 scale said low battery. After the battery (3V DL 2032) was replaced nothing works (does not turn on). Why would this happen? Is there a reset button or a button that turns it back on?

If you have already tried replacing the batteries in your Homedics SC-531 body fat scale and are still unsuccessful, try the following:
Voltage of the battery:
Verify that the batteries are inserted correctly with respect to polarity. When you put the batteries in the compartment, make sure the marks on the inside match up with the positive and negative ends.
Battery Reliability:
Use new, high-quality batteries exclusively. It is possible for batteries to be low on charge or have a problem, even if they are brand new.
Contacts for batteries:
Be sure there is no debris or rust on the battery contacts located inside the battery compartment. Use rubbing alcohol and a cotton swab to clean the contacts if corrosion is visible.
How to Reset:
On the scale, you should see a button or other option to reset it. You can restart the system by pressing a little reset button that is located on some scales. For instructions on how to find and utilize this feature, consult the handbook that came with your particular model.
Hold on a second.
Do not attempt to power on the scale until one minute has passed after you have replaced the batteries. It may take a bit for some electronic gadgets to reset.
Make sure nothing else is wrong.
Check the scale for obvious signs of wear and tear, such as loose pieces or cracked surfaces. Get in touch with the manufacturer's customer service department if you run into any problems.
Instruction Guide:
See the instructions that come with the scale for further information. It might provide advice on how to fix common power problems or detailed directions for fixing specific problems.
Get in touch with CS:
Get in touch with Homedics's support staff if the troubleshooting instructions don't solve the issue. Depending on the problem you're experiencing, they might be able to provide you with more precise advice or suggestions.
Always refer to the user manual for specific instructions on how to disassemble the scale before handling it, and be sure to follow any manufacturer-provided safety warnings. Contacting customer service is crucial if the scale is still within the warranty period.

The HoMedics digital scale SC-300 uses a CR2032 lithium coin cell battery. This battery has a diameter of 20mm and a thickness of 3.2mm, which makes it a small, flat battery that can easily fit into the scale.

Hello,
It's not a battery problem. The LCD panel of the DIGITAL SCALE has been wrong. Reasons: water, vapour, connector oxidation.

I have same problem with my scale. New batteries work for a few days. I'm throwing this thing out.

Open it again and make sure the battery is in the correct angle..... I have made this mistake from time to time

ensure the battery contacts are clean, if they are corroded it wont work. You may have to buy a contact cleaning spray or brush to do it.

Check to make sure you inserted the batteries correctly the plus signs should be up. If that doesn't work I reccomend contacting homedics customer support as something is worng with the scale that you cannot fix there is a lifetime limited warranty on the product so its better to let them try to fix the problem.
