Warning!! Your Amiga may be dying right in front of you! Check the battery!!

If its green it has leaked a long time ago ;-) and no its not good so do remove it and try and get all that "green stuff" away if there is some on the mobo a tooth brush is a nice thing to use :-).

If you don't want to worry about leaking replacement batteries, then use NiMh battery instead of Nicad. Much less harmfull. I should take my own advice too, but I used a Nicad. I will check up on it in a year or so. My a500+ i just removed the old battery. there is some leakage from when i got my a4000 but i think its not permanent damage and i have cleaned the mb as much as possible.

I know what you mean. I left my 500 in the closet for a couple of months and the next thin I know is that the mem expansion is dead... :-(

f its green it has leaked a long time ago  and no its not good so do remove it and try and get all that "green stuff" away if there is some on the mobo a tooth brush is a nice thing to use .

The motherbord is fine as battery is conected by 2 wires a fair distance away i will get a replacent battery something a bit newer or fit a lithium coin type battery. :-)

[amigamad]

What voltage is the battery is it 3.6 volt or lower. :-)

Does anyone know if the a500+ has a battery? im guessin it does seen as it has a BB clock in it... mines in the attic and i would like to know so i can fish it out and whip that battery out, damm thats a classic comp up there need to give it every chance of survival!!!

[amigamad]

I think you will find your a500+ does have a battery i know my a1500+ had one .but the a1500+i had will proberly die i gave it away ages ago and never relised the problems the battery causes. :-D

I agree very much...one day I'll sit down and remove all worn out batteries in my 11 of 13 Amigas in storage. (2 already converted)  I know how to clean up the circuit board. That is what happened to me in my Haunted House pinball machine, and it was a nightmare to fix it. (I successfully got it to work again  :-D ) But I really don't want to use batteries anymore.  There's a semiconductor called the "memory capacitor" that is leak-free and can last for probably 20 years.  The problem is that I can only find a 5V version.  I tried installing a 5V memory capacitor in my 4000 but the power only lasts for a few days.  All zorro original Amigas operate the RTC clock on 3.6V.  If anyone can find a 3V (or 3.6V) version, greater than 1 farad,  I greatly appreciate it!    :-)

Worst case scenerio?  Rebuild the 3.6V RTC circuit to work with 5V, and that means replacing all 3.6V components including the RTC chip. :-?

@RussellB

You're showing a perfect example of the memory capacitor we need to use instead of batteries.  (Those who don't know, it's the black round cover with metal casing exposed in the middle.)

It's 3.6V

Has the RTC battery been given any tought, when designing the A1 or Peg?
I mean is it easier to replace?
The Apricot PC (really old) used a 9v battery in the keyboard just flipp it over and switch.
The battery should be in a batteryholder for easier replacement.

I guess I'm lucky.  My A1200 FPU/RAM/RTC expansion board uses a plain old lithium battery.  I changed it anyway, though.  It finally died after 9 years of reliable timekeeping.   :-)

First thing I did when getting my Amiga 2000, open it up, and remove battery. Lucky for me it wasn't leaking at all yet. WHy do you need a soldering iron though? Mine came out perfectly with a pair of pliers.

[LocalH]

I should check my A3k's battery for that...I hope it's not too late, maybe that's why my fast RAM doesn't appear  :-(

When I dug my 2000 out of the loft recently I found the same thing.  Battery had leaked everywhere.  Cleaned up reasonably well, so rather than replace it with another one of those fixed barrel batteries, I found a 3.6V 280mAh NiMh universal battery with cables and terminal connectors.  Solder a pair of terminal posts onto the motherboard where the battery came out, and instant easily replaceable battery.
