SE/30 with a Maxell Battery Surprise
Posted by: JT737 on 2025-08-06 13:27:13
I've had this SE/30 sitting around for a year or so now. I meant to pull out the video card (another Interware VDR-2a) an inspect the motherboard when I got it, but never got around to it until today.

So I was pretty surprised to see that this has a Maxell battery in it.....that hasn't completely destroyed the board. The battery compartment contacts are gone, but the motherboard itself looks largely intact. I guess I will find out more (of the state of the motherboard) when I delve deeper into repairing it.

Only other damage I can see a little bit of rusting on the metal chassis.

Wow, that battery failure was downright gentle compared to most I've seen.

Almost looks like that SE/30 was stored upside down and the battery leaked onto the chassis instead of spilling all over the board.

It could have been SO much worse....

I know, right?! Every time I have opened up one of these with a Maxell battery, the board is usually a total lose. This was a first for me.

Kinda does, doesn't it? However, every time I encounter a Maxell battery bombed SE/30, the metal chassis is also rusted. I'm just glad it didn't take out the board!

One of the Centris/Quadra 650s that I got from @AppaloosaMac had the same thing occur. Maxell bomb had taken out the holder and rusted the drive chassis, but the rest of the board looked ok.
