PowerBook 17" Battery Recell?
Posted by: AlpineRaven on 2020-05-24 04:00:44
G'day all, 

I have two PowerBook G4 1.67ghz 17"  DLSD Laptops.

One of the 17" battery is no good/has less than 2 mins of charge left on it and other one has good charge. Saw the prices online of what is available and its too expensive.

I was wondering if anyone has any success re-celling those?

Cheers

AP

I currently rebuilding a iBook G4 14" battery and it hasn't been very difficult so far, pretty much just a case of remove the old cells and replace with new ones then charge cycle the pack until it figures out the correct capacity of the new cells.

The biggest challenge seems to be finding a trustworthy supplier of tabbed 18650's in the UK

EDIT: I am not sure of the construction of a DLSD battery though, it might be flat cells like the newer MacBook Battery's. In theory the process would still be the same but the cells would be much harder to find (and need to be handled with more care)

Going to need some of these myself (also in UK) for a similar purpose.  If you find anywhere good, let us know 🙂

Well the only source I have found I 100% trust is RS: https://uk.rs-online.com/web/p/speciality-size-rechargeable-batteries/8801551/   But at almost £10 a cell by the time you include VAT it's a little more than I was hoping to pay!

This company has the same cells for £3.99 each and will tab them for a additional £0.79 a cell https://www.ecoluxshopdirect.co.uk/samsung-18650-26f-2600mah-battery-301  I'm pretty sure I have brought from them on ebay in the past and the cells I got looked genuine and new

I would be careful, I've killed many of the little BMSes by reconnecting the cell wires in the wrong order.  Not shorting anything, just in the wrong order.  Something about it they don't like, and I'm not really sure what it was.
