1.33 12 inch (new) PowerBook battery

Message #1 - Posted 2004/04/24 - Thomas Garrou

I have just ordered a new 1.33 12 inch PB from CDW and have received an extra battery before delivery of the computer. The battery model number is M9324G/A. The Apple web site shows the battery for the new PB to be a different model number - M9572G/A.
CDW customer service states that the two batteries are identical. Does anyone know if there have been any changes in the specifications for batteries for the new 1.33 12 inch PowerBook?

Thanks in advance.

The battery has been changed to a 50 watt battery.

What does "50W battery mean"? Does it mean it has the same capacity but can deliver more power (up to 50W), thus has a lower internal resistance, or is it a misuse of "watt" that actually means something like "50WH" ?

It is 50 watt-hour. Sorry about leaving the H off. Too much of a hurry. I think the previous battery was 46 watt-hour.

Hmm, does this mean I can put a better batt. into my 1GHz 12" Albook??

From my knowledge the old PB G4 may hold those batteries:

A1022: 10.8 V * 4000 mAh = 40 Wh
M8984: 10.8 V * 4400 mAh = 47 Wh
M9324: 10.8 V * 4400 mAh = 47 Wh

From BTI:
MC-G4/12: 10.8 V * 4400 mAh = 47 Wh

I don't know the pysical dimensions yet. And I don't know yet whether the new battery will match the old one:
M9572: ? V * ? mAh = 50 Wh

Maybe you could measure the size and tell me the numbers?

What's the voltage of the new G4 PowerBooks? The old one Titaniums were 14.4. I suppose all the newer ones are 10.8 V!?

Martin
