One of the NES carts I'm giving my nephew for Christmas has a battery backup (Adventure of Link). I'd like to install a fresh battery before giving it to him. The reviews for batteries with tabs already attached make me leery of them. I think I'm better off with a fresh name brand one. I seem to end up soldering to coin cell batteries a few times a year, so I'm not new to it. (just did the cmos battery in my laptop last month) Basically, I scuff up the battery with sandpaper, apply liquid flux with a pen, solder the wire or tab, then try to solder that to the battery. Getting it to stick always seems to take too long and the battery always gets hotter than I'd like. Is there some trick to doing this that I don't know about? (aside from using an ultra$onic welder) |

You know, surprisingly, the batteries on my Zelda carts are still fine, and I bought them new BITD. I even lost one of them in a snow storm when I was a kid, only to find it a couple of days later. Do the batteries really wear out that often, or is it just a preventative measure? |

I opened the cartridge up, but I've been so busy lately that I can't remember if I measured the voltage on the battery already there. I would think a 30 year old battery would be suspect. |

I could never reliably solder to a battery. You've got enough room in the cartridge case that you could run two rig wires to a battery holder and hide it all internally..... Something like this: https://www.amazon.com/Saim-Plastic-CR2032-Battery-Sockets/dp/B00SUVK6FK/ref=sr_1_7?s=electronics&ie=UTF8&qid=1513807382&sr=1-7&keywords=Cr2032+battery+case |

pbj thats a great idea. idk why I never thought of that. I thought about replacing some batteries (just as preventative) before but my normal soldering sucks let alone trying on a battery. Will keep those in mind. :cheers: |
