Pinouts on titanium PB battery?

Message #1 - Posted 2003/12/08 - Joshua G Senecal

Hi All,

Does anyone know the pinouts on the battery used for the Titanium Powerbook (battery model M8511)? The battery has a connector with six contacts. One end of the connector is labeled +, the other -.

Are the six pins used to tap the battery at different voltages, or are only two of the pins connected, or...?

I ask because I'm looking for a good portable power source and the battery's specs fit my requirements perfectly. I just want to make sure I have a pretty good idea what I'm doing before I start connecting things to the pins.

Thanks!

Don't happen to know the pinout for the Ti PB battery, but usually the + and - are the only connections to the battery. The other connections go to the internal controller card and its temperature sensor so the power manager circuitry in the PB provides the correct charging current and will shutdown if the battery pack is in danger of overheating. The internal circuitry will also force a shutdown if the battery is nearly drained to protect the battery.
