Sinphaltimus Posted October 12, 2016 Share Posted October 12, 2016 Quick and easy mod for any A500 trap door ram expansion with RTC battery that is soldered to the board.Cleanly desoler old battery contacts from the board and insert new battery holder. I couldn't find the right size to exactly fit for this battery in the time frame I needed so I used a bigger one I purchase to do my YI mini memory module replacement.

+save2600 Posted October 12, 2016 Share Posted October 12, 2016 Did you also install a diode across the terminals so the recharging circuit doesn't fry your coin cell? Quote Link to comment Share on other sites More sharing options...
Sinphaltimus Posted October 12, 2016 Author Share Posted October 12, 2016 (edited) There wasn't one in place with the original soldered battery and the replacement is the same exact battery cr number. Why would a direct solder vs. A holder make any difference in regards to a diode? In other words, these aren't rechargeable (original or replacement) so I don't think there are any recharging circuits.

+save2600 Posted October 12, 2016 Share Posted October 12, 2016 My bad! Thought this was more like the A501 and others, with a rechargeable NiCad battery that likes to leak over time. Did the same thing to my TI Mini Memory module too, low profile CR2032 holder so it still fit in the case. Quote Link to comment Share on other sites More sharing options...
Sinphaltimus Posted October 12, 2016 Author Share Posted October 12, 2016 Sweet. Yeah me too. Posted about that in the TI forums. I actually surface mounted it on the outside of the cartridge. Quote Link to comment Share on other sites More sharing options...
