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.
