Pulled an Indigo from storage recently, only to find that the Sonneschein SL340 battery I put in many years ago had run out.

Since these batteries cost ~ 13EUR and require soldering I tried something else:

Nice.
I just found two of my Indigos with TOD symptoms, and was going to buy some Sonneschein batteries.
This might be a better solution for future battery changes.

Has anybody tried a lipo battery yet? I'm not sure if it's the right battery type for this application (wrt standby discharge, recharging, lack of cycling), but I bought some 240mah, 3.7V lipo cells from amazon at $2 each for my thesis project and used a lipo charging IC built into my shoe. Just a mini usb port coming out to recharge, everything else is ANT (wireless)

but the price is very right. lipo is much cheaper than the coin-cells I was planning to use, can be recharged, and has slightly higher capacity for the same size.. good thing since the battery only lasts about 20 hours in my application!

http://www.amazon.com/Upgraded-Syma-S10 ... 653&sr=8-5 (the ad says 200mah, but mine were marked 240mah, ymmv...)

The smallest lipo battery, coupled with a charging IC for when the machine is on, should ensure the battery never dies.. and if it does, just charge it up again?

For a moment I was all confused why your battery was in a different position than mine. Then I realized you are rocking it with an R4K Indigo.

I find that you can get as many CR2032's as you need from any PeeCee you get your hands on. It's about a penny each if you get them and most of the time they are still good.

And they come with the holder, which can usually be hacked into place.

I like mounting it on the DMUX - I have mine on the GIO blanking plate leg, and it just doesn't have a nice look and feel.

Well done Jan-Jaap.
I like that and how you revived this nice old Indigo...

Correct. That's where I got the donor cell


The holders from a PC mainboard are through-hole. The ones I have are SMD so they can be glued to any non-conductive surface. They cost ~ 1€, I think it's worth it. I've glued them on top of Dallas chips and even on an Onyx IO4 PCB.


Thanks. I think I'll have to revive half my Indigo2's and Indys as well next time I power them up

If you have an Ikea nearby, you may even find SOLVINDEN... 8 CR2032 batteries for 1.99$ (or 2.5'0€, or 5.95CHF, that's not fair).
But be careful, you always come back with a lot of useless things

Regarding the battery holder, I think I used that one once because there are no metal parts on the bottom. The contacts can be bent on the sides.
