If you already own an iCarsoft diagnostic tablet—or if you are planning to get one—you know the importance of having reliable data at your fingertips. But there is one critical component that standard OBDII scanning often overlooks until it’s too late: the battery.
Instead of buying a separate, bulky handheld battery tester, the iCarsoft BT900 Battery Test Clip offers a smarter solution. It is a "smart battery detection clip" designed to integrate seamlessly with your existing diagnostic tool.

Why Add the BT900 to Your Toolbox?
The BT900 isn't a standalone device. It connects to compatible iCarsoft tablets like the CR MAX, CR MAX BT, CR Eagle, and MT PRO. Here is how it helps in real-world situations:
Winter is tough on batteries. Before a long trip, use the BT900 to check the Cold Cranking Amps (CCA). It tells you if your battery has enough life left to start the engine in freezing temps.
Buying a used car? A battery might look new but be internally weak. The BT900 performs a comprehensive Charging System Test to reveal hidden alternator issues before you pay.

Using the BT900 is plug-and-play. It transforms your scanner into a powerful battery analyzer in seconds. Watch the quick demo below:
