Subject: Re: Replacing an A2000 battery
I
Some people get a common coin type battery and solder a battery holder to
where the old one was. Its better to replace the battery with a type that
will not leak or you will have to do this again in 5-10 years.
I just removed the battery in my A2000 and have yet to put another in since
I don't care about the time function.

tell if this
is only a colour change? Also, it looks like some of the
copper has been eaten away around where the negative part of the battery
was soldered to the motherboard.
sounds like the battery acid leaked out and started eating away. Only way
to know if damage has been done is to see if the board still works (boots)
or not. You can't really clean it off without doing some damage to the
traces.

"Precision Electronics Cleaner" from RS which is _supposed_ to
leave no residue.
Also, how are the solder tabs affixed to the battery? The replacement
batteries I got don't have any.
The tabe are usually spot welded on. Most cells are designed to go into
some sort of holder that has contacts. You might have to rig up a battery
with pigtail leads and attach that to the mobo, with the battery stuck on
somewhere with RTV or other adhesive.
