I would like to change my battery: which battery should I buy?
While changing the battery, it is generally advised to put in the same battery type that has already been in the car before. If another battery type has been installed, you have to ensure the following:
- The capacity of the new battery should not be smaller than that of the original one
- AGM batteries can only be exchanged with AGM batteries
In order to determine which battery type is currently installed, please use the app and follow these steps:
- Switch to “Battery Registration”
- Select “Register same type”
- The currently installed battery type is now visible in the app
In most cases, the following battery capacities are available for compatible models:
Some newer cars also support 105 Ah AGM batteries. Please check with the free basis version of the app if your car supports this capacity as well.
I can’t find the capacity of the battery in the app: which capacity should I select in the app?
The app determines directly from the car which battery capacities are supported by the ECUs. Therefore, none other than these can be put in.
If the capacity of the built-in battery isn’t selectable, put in the next smaller capacity of the same battery type that was built in.
If the history of the battery registration isn’t visible in your case
Please check if you have a stable connection and try to read out the battery registration history again. If that doesn't work, unfortunately it is currently not possible to read the battery registration history on all vehicle models. We are working on it. However, this problem never interferes with the function itself.
If you make the battery registration and get no error, then you can be sure that it worked. Your new battery is successfully registered.
The battery registration doesn’t work: what can I do?
If the battery registration fails, please try the following:
With GEN2 Scanner (Not Universal) wireless connection:
- switch Bluetooth off (iPhone/iPad)
- switch WiFi off (Android)
With Carly Universal Scanner :
- switch WiFi off
Let the engine run
Set communication speed to „slow“
The battery registration tells the car that some battery-related values have to be determined again. Therefore, never register or change the battery type while the car is driving!
