Replacing battery with Lithium Ion

[Zac67]

Just for completeness: lithium coin battery != lithium ion rechargeable battery - it's neither 'ion' nor rechargeable.

The lithum hack is very simple: you solder a germanium diode (just about any type) in line with the coin battery in order to prevent recharging the (non-rechargeable) battery. The only thing to worry about is to point the striped (cathode) end of the diode away from the + contact of the battery (or towards the - contact) and you're set.

CR2032 battery: 50c
battery clip: 1.20€ (salvaged from an old PC mobo: 0c)
germanium diode: 30c

So I am assuming there are many documented cases of batteries exploding inside Amiga computers?  When people buy C & D battery chargers and put non-rechargeable batteries in them are they exploding also?

Not that I know of exploded non-rechargeables in Amigas, but they do explode when charged (tried that with AAs myself). If the charging current is low enough you might get away with a dead battery instead of a burst one.

Anyway, I prefer replacing the battery with a rechargeable NiMH barrel-shaped one or 3 AAs in a clip, but putting them out of harm's way with a bit of cabling.

Either I've got some visual problems or the aw.de folks got the diode reversed... :roll:

PS: I've contacted Matthias about this and he's corrected the sketch - thanks! (FF needed a shift-reload to load the graphics).
