The Car+ device is suitable for 12V car battery (both wet and dry).
You may remove and reattach it securely. Once this device is blinking, you may proceed to authenticate the device with the Car+ mobile app.
For the first device installation, iOS users are required to input the Mac ID of the device into the app. The unique Mac ID can be found on the device and input without any colon. You can also send in a request via the help form in the app to verify your Mac ID.
No, it only draws a small current of 10mA.
Yes it is possible, however only one profile (e.g. email address) can be registered per device.
Yes, all you need to do is remove the device and reattach to your new car battery. Remember to update the profile on the Car+ app so you can keep track of the battery usage.
Chances are you have a Smart Alternator System on board your car. Smart alternator is also known as variable voltage alternator. The smart alternator system allows the vehicle to control the output voltage from the alternator based on vehicle operating conditions to reduce electrical load and in turn mechanical load on the engine by the alternator. Unlike smart alternator, the traditional fixed voltage alternator does not fluctuate the voltage supply.
When the car is driving, the smart alternator voltage fluctuate. As there are many makers of the smart alternator system, each fluctuation vary. As some smart alternator fluctuates the voltage up and down during a normal drive, the app may report messages, such as “Engine ON”, “Engine SHUT OFF”, “Crank to test battery” …etc, while the car engine is driving normally.
No. While many makers produce different Smart Alternator, the voltage fluctuation during cranking of all alternators types are the same. Car+ will still able to monitor the health of the battery for all alternator types.
Most likely your car has a Smart Alternator System, and have over-specification battery against a smaller engine. This configuration is common among electronic control to a turbocharged engine. Because the charge taken to crank the engine is not high, leaving a health charge after each crank. The Smart Alternator System will not charge the car battery to its fullness to conserve fuel. This healthy status remains until your battery is older and weaker. As then, the voltage drop each crank will be lower and it will trigger the Smart Alternator System to kick in the full charging. The app will start to advise on your battery normally.
In other words, there too many designs in the market to determine which configuration to register all the cranks. However, when the battery began to grow weak, its behaviour will all be the same despite which builds, which models, which configuration. Car+ App will be able to provide the proper advice when drivers need them the most.
