Pismo/Lombard PRAM battery source?

[emendelson]

Does anyone know a source for PRAM batteries for the Pismo or Lombard? My Pismo is working very nicely with a new SSD replacing the noisy HD, but the PRAM battery won't retain the date/time. I can't find a replacement at the usual suspects (eBay, Amazon, NewerTech, etc.), and I don't have the skills to build a new one.

Any information will be gratefully received.

Not sure where you are located, but this looks like a UK source for the Pismo/Lombard PRAM batteries. Rather pricey though at £26 (not much less than I paid for a Pismo in superb condition last year, with (you guessed it) a dead PRAM battery.

Thanks. That was one of the places I looked at. If you try to buy, they tell you "out of stock." Still looking!

It turns out there's hope. The eBay seller dasherdeals has already built some batteries for other PowerBook models, and he tells me that he'll start building them for Pismo/Lombard before too long. If you subscribe to his store (i.e. add it to your eBay feed) you'll see them when they're ready.

I've made a PowerBook pram battery tutorial.
Still no time to translate it into English - it's in German. But it includes many pictures and links:

BTW, which SSD drive do you have? I heard that many "compatible" drives simply do not work.

It says "Fashion Sprout SSD 2.5"; 32GB. I found it on eBay for a few dollars. And DasherDeals on eBay now is selling PRAM batteries, so I can even get the right time on this machine.

I realize this is an old thread, but for my Pismo PRAM battery rebuild, I used 4x VL2330 coin type cells.

Photos of the rebuild process are detailed on this thread:

I've done exactly the same rebuild. The batteries are a little tricky to solder to, and you don't want to overheat them, but if you take your time it's easy enough.
