It would be helpful to know whether a new PRAM battery unit needs charging as in this article

https://discussions.apple.com/thread/239...

or whether it is assumed that it will start charging in the course of normal use.

Ben Bradley - Antwort

from looking at other pictures of the PRAM module it appears to have a removable Lithium Coin battery.

Is this battery something standard that I can just pop the old one out and replace it,

or is it special in that it can be recharged or such ??

It is not standard but you can change it anyway...

PowerBook G4 PRAM Battery Replacement

The Apple part number (MPN) for the board that this PRAM is connected to inside an A1138 PowerBook is 820-1819-A.

The MPN for the board inside an A1107 PowerBook is 820-1814-A.

The only available Li-Po battery replacement I can find with the required 2-pin connector already attached to the wires is the CS-AP1107SL by Cameron Sino. However, this battery is marketed as compatible with the A1107 or more generally with the 17-inch PowerBooks.

I wonder why it is not also marketed as compatible with the A1138. According to https://www.smallbattery.company.org.uk/... the LP302030 battery is used on both 820-1819-A and 820-1814-A boards.

While the boards may be different, I think that the rectangular 3.7 V Li-Po battery packs can be used in any 15-inch and 17-inch PowerBook.
