Thanks! Now I just have to source/build a new PRAM battery...
It looks like two Sanyo ML2430. I guess if I cut it apart I can get the part number for sure.Attachments

Just as a warning - I think some of the PowerBook models will only charge the PRAM battery if the main battery is functional. Of course, that only applies to models that use a rechargeable Lithium cell.
In any case, there's a guy on eBay making new ones: https://www.ebay.com/itm/325429557742
Also, if you're going to be taking apart the LCD to recap it (which you should by the way), I'm currently missing the cap values for the 2300c LCD, and I could also really use the part number for it for this list on my website as well: https://macdat.net/macintosh/powerbook/general/powerbooklcdindex.html

This is a Duo 230 upgraded to a 2300 so it doesn't have a color LCD. Let me know if you still need pictures.

Ahhh, right. I don't think I have a reference photo for the 230 LCD so that could be useful, but if its already been recapped, then that dilutes the usefulness of a photo.
Seems like this thread has a photo of the 230 LCD:

Ah, well yes, I know what they do look like but I need an image that I have permission to use on my website. I can’t just take some guy’s image, or at least I’m not going to do that.

I wish I had known about those new pram batteries a while ago when I needed them, but I already ordered the parts to just make them myself.
The 35v cap (at least the ones I have) are quite difficult to install as they are much larger than the original and barely fit on the pads. Might be worth it to buy a 25v if you can confirm your model has a 25v cap (my 280 and 230 both are 25v but some are unmarked).
If you would like, I can get a photo of the display since mine has not been recapped yet and is not a hassle to open. Always happy to help where I can.

No problem. Sure, my goal in creating/posting stuff like this is to hopefully be of help to others, so increased visibility sounds good to me.
