It won’t I’m afraid. I would say that it’s leaking but the fact is that it leaked then dried up entirely a decade ago. It’s 20 years old and obsolete technology and you better be sure that all these vendors who advertise them as supplied but are ‘out of stock’ have a website that they don’t update or purposely leave stuff on to help their search engine optimisation.
Next you may consider those great YouTube videos that show how to jump start old batteries using nothing more than a laptop and a butchered usb cable. That may work on some modern batteries that have dropped below a certain charge. Not in this case. In this case you may as well try to jump start a potato.
The good news is that we figured out how you can replace the original lithium ion cells with lipo or lithium poli. First you have to remove the old dead cells though as shown in the next part of the tutorials.
Usual disclaimer – for fun only and at your own risk. Enjoy.
