Removing Di2 Battery from seatpost

I'm going to be switching seat posts soon and wanted to ask the community if there were any tips/tricks to removing the battery. Current setup is standard Shimano friction battery holder....not the lock ring type.

My guess is to carefully use pliers on the tabs to pull and rotate the assembly out from the post. Anyone done this before that could offer any insight? I just want to be prepared when the new seat post arrives.

Not much info using Google other than some people suggesting use of a coat hanger....but they do not explain how it is used, nor can I imagine it being an effective method.

Thanks

For next time, maybe attach a string or ribbon so that you can more easily pull it out.

I didn't install it, but if I did that would be a good idea.

There must be some bike mechanics on here that have done this many times. Strange that the web has very little information on this.

If it's held by friction, not much else you can do but pull it out slowly... If you can shim the tube from a can of wd40, a small squirt may make it easier to pull out... but cleanup will be required.

Mine went into the seatpost never to see the light of day again.

Looking at photos from my install, I would think that it could probably be pulled out by hand, or maybe pliers or a screwdriver to get it started as the OP has stated. Doesn't look like a big deal at all.

This is the Ritchie holder, not Shimano...

true that...... but I also have almost put out an eye by trying to remove a valve core without letting the air out of a tire first.... so I should add "do this at your own risk"

and @ChinookTx I am from ChinookMt
