Battery Tool

The Chipmunk Battery Tool is an easy to use tool to see many interesting things about an Apple Battery.

It does many things:

1- Shows the Cycle Count

2- Shows Serial Number

3- Shows Capacity that the battery still has left

4- Shows if the 'Permanent Fail' Flag has been set, plus the reason why it has been set.

One of the uses is to distinguish between batteries that are dead and ones that are merely very discharged. If you charge a severely discharged battery VERY carefully it is often possible to bring it back to life. Within the Mac this will not happen because the Mac will only charge the battery once it can talk to the battery, but the discharged battery will not talk until it is charged (a little bit).

This tool can also write some parameters into the battery. It can set the cycle count as well as the 'original' capacity. The health of the battery is the current capacity as compared to the original capacity. So lowering the 'original' capacity would give a higher percentage for the health.

This Chipmunk Battery Tool can also clear the Permanent Fail (PF) flag in case it has come on. This might or might not fix the battery depending on the reason that the PF got set. If it got set because the battery was discharged too much or because you accidentally short circuited the battery briefly it will come back to life. But if, for example, the PF flag is set because because one cell is dead, resetting the PF flag will not solve the problem obviously, and the PF flag will probably come back on a few seconds later.

Adaptor boards for the Battery Tool

Because batteries can have many different connectors there are many different adapter boards available. We sell the separately so you only have to buy the ones that you need.The Adaptor boards for many newer come with the connector already mounted, but most of the Adaptor Boards for the older models require you to harvest the connector off an old motherboard and mount it yourself. This is because we can not buy the proprietary connectors anywhere.

You can order the Battery tool with any combination of Adaptors that you like. Just tell us on email or Whatsapp what you want and we will send you a payment link for the combination you chose.
