Video doorbell battery won't charge

Symptoms

• Charging light doesn't turn on when plugged in
• Battery percentage doesn't move after hours of charging
• Doorbell only charges intermittently
• Battery shows full but drains within minutes of remounting

Likely causes

• CommonFaulty or low-quality charging cableA worn USB cable is a very common reason a battery doesn't seem to charge.
• CommonDirty charging port or contact pinsDust or corrosion on the charging pins prevents a full connection.
• PossibleWeak or incorrect power adapterUsing a low-output adapter can result in extremely slow or stalled charging.
• PossibleBattery not seated correctly if removableSome doorbells use a removable battery pack that must click firmly into place.
• Less commonBattery has reached end of lifeRechargeable batteries eventually lose the ability to hold or accept a charge after years of cycles.

What to do

1. Try a different USB cable and wall adapter known to work with other devices.
2. Clean the charging port or contact pins gently with a dry cloth or soft brush.
3. Watch for a charging indicator light and consult the manual for what a normal charging light looks like.
4. If the battery is removable, take it out and reseat it firmly, checking for a physical click.
5. Let it charge for at least 4–6 hours before assuming it isn't working, since a fully drained battery can be slow to start.
6. Try charging the battery indoors at room temperature, since extreme cold or heat can block charging as a safety feature.
7. Replace the battery pack if it never accepts a charge after trying another cable, adapter, and port cleaning.

Tools and parts

• Soft cloth or brush

When to call a pro

If the battery is swollen, contact the manufacturer for a proper replacement and disposal rather than attempting to charge or open it.
