ONE x Battery Simulator for MacBook Air A1466 (A4593)

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.
