Apple Macintosh PowerBook 140/170 Rechargeable Battery M5417 Vintage UNTESTED
This is a NiCad battery for the PowerBook 140/170, I believe it should work with other 100 series models such as 160/180, etc but I am unsure.
Any NiCad battery of this age has failed at this point, so it’s unlikely this one will hold a charge. No external signs of corrosion or leaking cells.
It is UNTESTED AND SOLD AS-IS, may be a good candidate for rebuilding or to complete your PowerBook.
Thanks for looking!
