Blue PRAM Battery Leaked! Radius 81/110 victim and assorted questions . . .

[Trash80toHP_Mini]

. . . at least I think I pulled out one of the Naked Blue Cells I bought new in the 20Kteens? Gotta find the baggie, definitely wasn't MAXELL anyway.

At any rate, if you have the plain Blue 1/3AA cells, pull 'em! Never seen one of these fail before. Been trying to get at every machine to make sure no cells remain in any of them. I'll install them for playtime only.

Which brings up the question of the day; who makes/sells the best button battery holder/replacement thingie for the stationary setups?

Another Question: Are all Macintosh II PRAM Battery pairs Axials that are soldered to the logic board?

I've got a first release Macintosh II.0 that I haven't even tested yet. It pre-dates the NuChip ASIC Macintosh II.1. So wondering if this is just my problem or everyone with a Macintosh II has gone through it?

How are they usually replaced? Seems like the perfect victim for a soldered down Button Cell mod? Is it safe to test it with those suckers still in there?

Some are soldered straight to the board, some have a funny little daughter card thing that Apple started fitting to later IIxes and retrofitting to older ones and Mac IIs.

PS never consider any battery to be leak proof.

I got a two battery cell switched coin cell holder on flying leads, and modified it to take a wire from the middle of the two batteries, then wired it into my IIx and velcro'd it down to stop it rattling.
