About replacing a Sega CD internal battery

unknowncheeseunknowncheese
in Help Wanted!
Got myself a shiny, working Model 2 and it seems the battery was borked. Since I have no soldering iron or experience, is it possible to replace it the ghetto way with electrical tape? And which type of battery am I supposed to be using? From what I understand the original battery would recharge itself, but lots of people seem to be using non-rechargable batteries as replacements. Won't the battery burst or leak if the system is trying to recharge it when the battery can't take it?

    If the system has a charging circuit then you need to disable the charging circuit to use a standard battery. So yes plugging in a standard CR2032 is a bad idea. Also the battery is soldered in place. You might as well find someone who can replace the battery with a socket for you and do it the right way. Otherwise you will likely end up regretting it later. Not sure where you are located but I install sockets when doing battery replacements.

    Canada, so having you do it isn't exactly feasible. 



    With a quick look online an ML2032 battery is rechargable and would work?

    Yes. In Canada you could reach out to Leon Kiriliuk.

    Yes as in that particular battery will work? You're like the Sega master.

    You may be better off buying a $12 soldering iron from Wal-Mart and doing it yourself...just watch a few YouTube videos on soldering for a tutorial. I did this a year or two ago and it was super easy. Now all simple soldering jobs I do myself then outsource all the complex stuff.

    Personally I prefer to use the LR2032. It's a lithium-ion rechargeable. However the ML2032 will also work. It's the maxell brand rechargeable. Pretty common battery. Definitely socket it though. The sockets cost practically nothing. Just desolder the existing battery and solder the socket in it's place. Make sure you match up the correct ins for positive and negative. Then you can easily replace the battery in the future.

    Went to the shop and got a cheapo iron and a spool of solder. No shops around here carried rechargeable 2032 batteries though. Went ahead and ordered a couple LIR2032 and those socket things to put them in. Hopefully I can get this working once they arrive.



    Thanks to all you fine people for the help.

    Get a piece of junk electronics to practice with before you just have at it. You don't want to lift a trace.

    Got it done. Put in a socket so I won't have to do this again. At least with the Sega CD.



    Absolute hackjob, but it seems to be working.

    Pictures?

    I'm sure you can tell where from the one huge glob of solder and all the burn marks.



    The position of the board wasn't ideal either. I tried pulling on the white connector things that have all the cables from the CD drive but they wouldn't come out. I was afraid of pulling too hard to so I the board up on it's side and propped something against it to help keep it from falling over while I tried to desolder the old battery.



    Working anyway. The old battery was deleting everything whenever I'd turn it off and then require me to format the ram again when I turned it back on. It's retaining the saves now.

    Not the worst I have ever seen. With the socket in there now, at least you won't need to do it again.
