Battery 15% alert
Tedee PRO smart lock Battery 15% alert: recharge needed
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Tedee PRO's 15% battery notification means charging should be arranged while some power remains. Check the level in the app and use the supplied magnetic cable to charge the mounted lock; a full charge takes approximately six hours.
Safety first
Stop and check this first
- Charge a door-mounted Tedee PRO with the supplied magnetic cable: Tedee advises against other cables in that position, while the intended magnetic connection can separate safely if the lock rotates.
Safe checks you can perform
- Confirm your Tedee PRO notification and reported charge
- Connect the magnetic charging cable to the mounted lock
- Inspect the percentage after the approximate charging period
Leave these tasks to a qualified professional
- Do not attempt this professional task: Verify the documented external charging setup for PRO
- Do not attempt this professional task: Review whether PRO bolt travel adds avoidable energy use
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Verify the documented external charging setup for PRO
What they doThe technician checks the magnetic adapter, supplied cable and USB power connection, then records battery status before and after the charging period.
They must show youthe supplied cable attached to the side adapter and the battery readings in the app.
In writingcharging duration, USB power source and the percentages observed before and after the 15% notification.
Review whether PRO bolt travel adds avoidable energy use
What they doWhen reviewing calibration because of recharge frequency, the professional observes full bolt extension and retraction with the door open and confirms those limits in device settings.
They must show youthe fully extended and fully retracted bolt references used to calibrate your PRO.
In writingwhether spare rotation existed, which travel references were confirmed and the battery level recorded during the review.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Confirm your Tedee PRO notification and reported charge
- Who:
- you, in the Tedee application associated with your PRO device.
- How:
- inspect battery status in the device list and on the lock's main control screen, then record the percentage alongside the notification you received.
- Result that matters:
- check the battery reading accompanying the default 15% warning before recharging.
- If the app reports low charge for your PRO:
- prepare the supplied cable for external charging.
- If your device is a Tedee GO:
- use its model-specific guidance because this charging procedure covers PRO only.
- Evidence to keep:
- confirmed model, displayed percentage and time of the low-battery notification.
Evidence: Tedee PRO charging
Connect the magnetic charging cable to the mounted lock
- Who:
- you, with the included charging cable and access to Tedee PRO's side port.
- How:
- insert the magnetic adapter into the side micro USB port first, attach the cable to that adapter next, and connect its USB end to a power bank as described by Tedee.
- Result that matters:
- use the magnetic connection intended for charging PRO while it remains on the door.
- If the supplied cable is available:
- retain that connection for the manufacturer's charging period.
- If only another micro USB cable is available:
- do not use it on the mounted lock and discuss the official alternative with a professional.
- Evidence to keep:
- identification of the included cable and the USB power source used for this charge.
Evidence: Tedee PRO charging
Inspect the percentage after the approximate charging period
- Who:
- you, checking the application again after charging Tedee PRO.
- How:
- allow approximately six hours as the reference for a full charge, review battery status in the app and, once charging is complete, remove the adapter if you want to store it until next time.
- Result that matters:
- document how the integrated battery percentage changes during the charging session.
- If the recorded level increases while charging:
- keep the final reading for comparison with the next notification.
- If the percentage does not progress or the alert persists after charging:
- provide Tedee with the readings and connection details.
- Evidence to keep:
- starting and ending percentages, approximate connection time and whether the notification remains.
Evidence: Tedee PRO charging

What it means
The official Tedee PRO: charging page gives 15% as the default low-battery notification threshold for the PRO family and explains that power still remains. Battery status is available in the device list and main control screen. This charging guide excludes Tedee GO, and other models can use different power arrangements and alerts. Battery 15% alert by itself never establishes that the battery or charging circuit is defective.
Warnings and stop conditions

Charge a door-mounted Tedee PRO with the supplied magnetic cable: Tedee advises against other cables in that position, while the intended magnetic connection can separate safely if the lock rotates.
Evidence: Tedee PRO charging
Symptoms and causes
Probable causes · in order
- Remaining charge reaches the notification thresholdCommon
Tedee PRO issues its default notification when battery charge reaches 15%, providing notice to arrange charging while energy remains available.
Evidence: Tedee PRO charging
- Unnecessary rotation retained during calibrationPossible
If rotation continued after the bolts were fully extended or hidden, the GO/PRO calibration guide explains that operations take longer and consume additional energy.
Evidence: Tedee GO and Tedee PRO calibration
