Removing battery from A2000?

[runequester]

Ive been told a few times that you should remove the battery from a 2000 motherboard as it may leak and cause damage.

So here's the noob question:

How do I identify the battery and how do I safely remove it?

It is the empty slot in these images BT800.... I have removed so many batteries and all I do is gently rock it side to side until it snaps off. But do at your own risk. Others will tell you to desolder etc to remove it. But if the battery is leaking I just like to get it off. The A3000 is the only one I would actually remove by desoldering. The A2000 is just so simple.

The battery will look like one of these [ the one below is in an A4000 ]

PS This is a great tutorial on batteries

alright, I'll take it apart and take a look.

If it isn't leaking, would you still recommend taking it off ?

What exactly do I lose if I remove it ? Just the clock ?

I don't like not having a battery. The only real problem is all of the files you save will have the same, useless, date without a battery.
I prefer changing to a coin type battery, that can be easily changed when needed. Just make sure you add a diode in that setup.

well, at the moment I dont have a hard drive anyways so I guess its not a big deal.

You don't lose the clock, it just has to be set to the correct time/date everytime you boot your Amiga.  Not worth risking having it around even if it's not leaking-- think of it as a time bomb.  You could go for the coin type non-leaking battery if your games save your high scores with date/time.

Those A500 memory expansion boards also have batteries in them that look the same as the pictures shown by another poster.  They also go bad, and those metal things are hard to take apart to get to the battery but at least the A500/A1000 MBs don't have time bombs planted on them.

alright. I'll take her apart tonight and see what I can do inside.

Yes.. It could start leaking at any moment if it by some miracle hasnt started leaking yet.

The only thing without battery its you will need set the time and date when you boot the Amiga (only if you want), but not problem if t not have the battery.
The other thing is, if you not have skills to use any soldering, you can revome cutting the ping legs, with any cutter/plier

I removed the batteries from all my amigas without needing any desoldering equipment.  And A2000 has more room to work with near the battery area so unlikely to screw up any components/traces near it.  The A3000/A4000 battery is in a more congested spot.

It's not terribly difficult to remove the battery TBH. A pair of sharp scissors will do the trick.
My thread about my old 2000 HERE shows exactly what it looks like.
My thread on Amibay HERE shows the removal process on an a500+ which is very similar indeed.
It is always worthwhile snipping the battery off first before desoldering the legs, as it acts as a heatsink. combined with the fact that it is connected to a rather large ground which also acts as a heatsink means that it can be tricky to remove with just a soldering iron, hot air is really useful here.
The main thing is to get the battery off, and clean off any residue.
