jonas778 Posted October 22 Share Posted October 22 When storing electronic devices that use CR2032 batteries for a long time, is there a risk that the battery will leak and corrode the PCB? Does this type of battery undergo chemical reactions and changes? Link to comment Share on other sites More sharing options...
chenbeier Posted October 22 Share Posted October 22 Of course yes, like every battery it will corrode and can harm electronically devices. Link to comment Share on other sites More sharing options...

MigL Posted October 23 Share Posted October 23 I have never found the 'coin' type batteries, such as CR2032, to leak, and I have some computer motherboards that are >20 years old ( I keep them for 'sentimental' reasons 😃 ). Similarly, my key fob remote operated with a CR2032 for over 10 years, and didn't leak. What I have had 'leakage' issues with is the tube style AA, or AAA, type batteries in my Digital multi-meters. I have now started removing the batteries from my 'good' meters, and only keep them in the cheap Aneng meter ( which is cheap enough to be disposable ), but if I need a meter for mains, or higher, I need to replace batteries in the Fluke.

That is your experience, I have another one. Old Lithiumcells get a white residue coming out the battery. Link to comment Share on other sites More sharing options...
studiot Posted October 23 Share Posted October 23 You can get these coin cells in Alkaline, Lithium and Silver Oxide chemistry in increasing order of cost and life expectancy. The sliver oxide ones tend to be leak free and the alkaline ones the worst. Link to comment Share on other sites More sharing options...
jonas778 Posted October 23 Author Share Posted October 23 Is the CR2032 battery in the PS2 Slim 90000 alkaline or oxide? I think it's a Mitsubishi but I don't know if it's original Link to comment Share on other sites More sharing options...
pzkpfw Posted October 23 Share Posted October 23 gamer87 often had similar concerns, and also had this machine. Maybe they have advice for you? https://www.scienceforums.net/topic/124822-question-uv-plastic-and-rubber Link to comment Share on other sites More sharing options...

studiot Posted October 23 Share Posted October 23 It is worth noting that coin cell batteries perform two different functions and I cannot tell which one the play station uses. In some applications they battery is only there as a voltage source. The current drain is negligible. There will be little or no leakage at the end of this application. It is used to refresh the setting memory in computer apps (Bios) for instance. Other equipment use coin cells as a power source. The current flow generates the chemical reactions that produce the leakage products. For instance in kitchen scales, micrometers and so on.

jonas778 Posted October 26 Author Share Posted October 26 In the case of the PS2 Slim 90000 video game, this CR2032 battery is used to store the date and time. Is there a risk of it leaking and corroding the PCB? Link to comment Share on other sites More sharing options...
