Q-133 battery - Remove it now!

Q-133 battery - Remove it now!

2013-04-11 by horiprod

Hi All. Just to endorse what WT said r/e Q-133 batteries - Rip them out now! I've had two instances within a week whereby lithium batteries leaking corrosive chemicals have completely destroyed CMI cards. SO, I went through every CMI-133 I had. Not one had more than 10mV in, and some were bulging worryingly (see pictures). The battery is only used to keep the time and date clock chip powered when the mains is off. You can also use other batteries if the original Tadran is hard to get. Or run it without one - losing the clock isn't the end of the world! 
Regards, Peter W, in sunny Sydney.

PS: More shameless plugs of Fairlight gear on the bay of E:

Take a picture so you know how to reattach the cables.

You need soldering skills to properly remove the battery. It is a usually
purple fairly big round flat item. If you do not have soldering experience
it is best to remove the board and store it outside of the case so if it
starts leaking at least the rest of the system does not get affected. Have
the battery removed by someone else.
