The Clarke CBBT1 Bluetooth Battery Tester gives drivers a way to watch their car’s power source without a garage visit, and the device fits in a pocket for easy placement.
Manufactured by Clarke, the unit sticks to the battery’s surface with double‑sided tape and clips onto the terminals. Its compact shape means it won’t interfere with other components, and it stays in place even on bumpy rides.
Once attached, the tester links to a dedicated mobile app via Bluetooth. The connection is initiated with a single tap, and the app begins displaying voltage, temperature and overall power level in real time.
If the readings stray from normal ranges, a push notification appears on the phone. Users get a heads‑up before a loss of charge could strand them, and the alert includes a suggested next step based on the data.
All measurements are logged for a rolling 30‑day period, allowing owners to spot gradual declines. The raw numbers can be exported for deeper analysis, though most drivers find the visual graphs sufficient for everyday monitoring.
At a price of £24.99, the kit competes with higher‑priced alternatives that lack wireless reporting. The cost‑to‑feature ratio has drawn attention from budget‑conscious motorists who still want reliable oversight.
How the Unit Connects and Reports Data
The companion app organizes information into three tabs: live status, history and settings. Live status shows current voltage, temperature and an overall health score derived from the manufacturer’s algorithm.

History stores each reading with a timestamp, and users can scroll back to see how the power source behaved during specific trips.
Data updates instantly.
Settings let owners calibrate alert thresholds, change the Bluetooth name and enable a silent mode for nighttime monitoring. The interface is simple enough that even those unfamiliar with diagnostics can use it without a manual.
Data export is performed via a CSV file that opens in spreadsheet programs. This feature is handy for fleet managers who need to keep records for compliance or maintenance scheduling.
Additional Functions for Drivers
Beyond power monitoring, the tester records distance traveled, fuel cost estimates and driving habits such as acceleration patterns. These metrics are compiled automatically, requiring no extra input from the user.
Convenient tracking.
Exported logs can be filtered by date, route or vehicle, making it easier to calculate expenses for tax or budgeting purposes. The spreadsheet format also allows third‑party tools to generate custom reports.

Another practical addition is the automatic parking‑location logger. When a vehicle is turned off, the unit captures the GPS coordinates and stores them in the app. If the driver forgets where they left the car, a single tap reveals the last known spot.
A tiny mechanic on board.
For everyday commuters, the combination of real‑time alerts and trip‑tracking can reduce surprise breakdowns and help plan maintenance before costly repairs arise.
Installation takes minutes.
The ongoing data stream keeps owners informed without extra effort.
Overall, the Clarke CBBT1 offers a blend of diagnostics and convenience that many drivers find valuable, especially given its modest price tag. The product is available through major retailers, and the packaging includes a quick‑start guide to get the unit up and running.
