bios battery replacements

None i know even use cordless phones, so packs like that aren't too common around here either, atleast i've not seen any when looking for other batteries.

But i bet those cost more than the nimh batteries i found on a site anyway...

In case there's a language misunderstanding about "mobile phone", we're talking about a battery pack like the ones below for cordless phones (the kind you use in the house) and not cell phones (like you use in your car and build at Nokia). Here in North America you can buy those pretty well everywhere for one or two dollars, whereas cell phone batteries are much more expensive.

Mike, this is Finland! Nobody uses a landline anymore--they've all got Nokia mobiles! (Probably even in Lapland)
 
Thats wrong chuck, land lines are used all the time however many use mostly mobile phones these days but the lines are used for adsl for instance, i however have managed to get rid of that line and get a fiber optic connection :)
 
I was joking, Elvi. Nokia seems so ubiquitous in Finland that one might get the idea that nobody uses a land land. As for fiber optic, I'm envious.

Do you have hobby shops anywhere near you? I was thinking that rechargeable battery packs are also common with radio-controlled toys.
 
I'll have to look into that but i don't remember any and i just looked at these packs on the same site i found the nimh's and the packs cost more :/

But what do you say to my edit chuck? i thought it was a rechargable one and now when i took it loose it says "don't recharche" and i know the battery pinns on the tandon gives a 4.5v charge.
 
Okay, you have a lithium cell in the Tandon. So any non-rechargeable combination of cells should do. You could replace it with any capacity 3.6V (or 4.5V) cell, although lithium will last longest, but alkaline will also work. The current draw on these things is very small, so batteries tend to last their shelf life.
 
I'm a litle worrid of using non rechargeable ones on those 2 pinns, just mesured with a volt meter on the pinns and it was showing 4.8V without the dead battery there.

I do have 4 rechargeable AA batteries but they are only 1.2V a piece so i'd have to use 3 of them to get the right or enough volts, tho these are 2600mAh a piece so maybe a litle large.
Also just tried with 2 lithium AAA batteries making a litle over 3V so that works.

Just a litle update, i think the tandon knows if it's a recharge battery or not, here's what i did: pluged in 2 AAA to the mobo and turned the pc on.
Mesured the voltages on the battery pinns with the batteries attached: 3.1V.
Unplugged the batteries with the pc running and mesured the pinns on the mobo: 4.8V.
Reattached the batteries to the pinns and remesured, back down to 3.1V so it seems this solution works atleast for the tandon :)
 
Well no, your battery is simply acting as a current sink for the charging current. Still, it may not matter if the charging current is small enough. Operate the system for a few hours and then check to see if your AAA cells are warm to the touch. If so, you're probably in a dangerous situation--the battery could build up internal heat and rupture. Why not simply replace them with off-the shelf AAA rechargeable batteries?

uh well now i don't understand you att all, the old battery was a lithium 3.6v, a non rechargebale battery so why wouldn't this work?
 
And... battery replacements done, more or less.
Noticed i had another 386 with a dead battery but it's not leaking and is a lithium so changing that is as easy as changing for the tandon that had the maxell battery.
 
The cr2032 works fine for some applications replacing a 3.6v battery that is rechargable or not. It's used quite a lot (WITH diode) to replace Amiga 4000 batteries (which I am going to do one day to my working 4000).

I replaced the TL-5186 in my R4000 SGI Iris Indigo with a remote holder with cr2032. I'd be happy if it just lasted for a few years.
