Battery Port Tester / Known Good Battery

The CMIzapper Battery Port Tester is an easy to use tool to see many interesting things about a Mac motherboard you are working on.

It does two things:

1- It 'pretends' to be a battery. Essentially it is a 'Known Good' Battery. So no need to connect a real, bulky, expensive and vulnerable battery wile repairing. Many Macs will not power-on without a battery, and many (≥ 2011) will run at 1/4 speed without a battery. Plugging in the CMIzapper Battery Port Tester is much easier and safer than using a real (Apple) battery.

2- The tester has many LEDs that give you useful information about what is and what is not working on the Mac motherboard.

It shows if the SMC is alive and running.

It shows if the charger controller (ISL) is alive and running by communicating with it.

It shows you if the Mac is trying to charge the 'battery'.

It shows if the charging voltage is dangerously high (plus the speaker will bleep to warn you).

If there is a problem with the I2C bus itself it will tell you the problem.


It can also be connected to the Medusa in Listener mode. The display of the Medusa will show even more information:

The charging voltage supplied by the Mac

The value of System Presence Detect resistor R6950. This resistor in the Mac tells the battery to talk to the Mac.

Ordering:

Different Macs will need different versions of this board.

You will have to connect the plug from an old battery of the appropriate model.

Price 85 euro (mount your own battery plug)


For some models we have some plugs ourselves and can supply the Battery Port Tester with a plug. Please contact us and tell us what model you are looking for with plug.

Price 105 euro (with battery plug mounted)
