Before changing a makeup mirror battery, identify how the mirror is powered. A removable AA or AAA battery compartment needs a different approach from a built-in rechargeable battery. A plug-in mirror may have no battery to replace.
For example, this round makeup mirror with rechargeable and plug-in versions offers separate power choices. Select the correct version and follow its charging instructions; do not treat the built-in rechargeable version as an AA-battery mirror.
Check the Power Type First
- Replaceable batteries: read the compartment label or instructions for the exact battery type and quantity.
- Built-in rechargeable battery: charge it using the specified cable and power supply. Do not open a sealed housing to replace the battery yourself.
- Plug-in version: check the external power supply rather than looking for a battery compartment.
If you are choosing a replacement mirror, our makeup mirrors with rechargeable and plug-in options let you compare the versions before ordering. The Charge selector identifies which version you are buying.
How to Replace Removable Batteries
- Switch off the mirror and disconnect any external power lead.
- Place it securely on a soft, dry surface, protecting the glass.
- Open only the battery compartment described in the instructions. Do not force a panel or remove the mirror glass.
- Note the polarity markings and remove the old batteries.
- Fit the specified fresh batteries in the correct orientation. Replace the whole set together; do not mix old and new batteries or different types.
- Close the compartment securely, then test the mirror.
If Your Mirror Is Rechargeable
Use the charging method specified for your model and allow the recommended charging time. Keep the charging connection dry. If it still will not charge, check the cable for visible damage and ask the retailer for model-specific support. A phone-charging USB outlet on a mirror does not necessarily charge the mirror itself.
For example, the arched model with a 10X magnifier offers separate Rechargeable and Plugin choices. Selecting Plugin does not give you a cordless battery version. Battery capacity and charging time should be checked for the chosen model, not assumed from its shape or size.
When a Battery Change Will Not Solve the Problem
Dim lighting can also be caused by a low brightness setting, a connection problem or a failed component. Check the controls and supplied instructions first. If you see leakage, swelling, unusual heat or damage, stop using the mirror and contact the supplier. Do not attempt to repair a battery pack.
Frequently Asked Questions
Can I replace a built-in rechargeable battery with AA batteries?
No. Use only the power system designed for that mirror. A sealed rechargeable pack is not interchangeable with loose batteries.
How often should I change the batteries?
There is no universal interval. It depends on battery type, brightness and daily use. Follow the model instructions and replace removable batteries when appropriate.
What if fresh batteries do not help?
Check polarity and the selected lighting setting. For further checks, read our lighted makeup mirror troubleshooting guide or contact support.
