replacing SNES game battery

[munchiaz]

So i have never done this before. I want to start playing my copies of soul blazer and illusion of gaia, but i dont want the batteries to crap out on me. Ive seen a few videos on youtube, all with difference methods on how to replace the battery. But i wanted to hear from you guys on what you think is the best and easiest way to do it. Also if you can post links to the tools and materials i would need that would be awesome

The best method is to use one of these and solder it in. You can also use a regular battery and tape it, but that method sucks. Don't forget you need a gamebit to open the cart.

Yeah. I tried the taping method. Don't do it.

If only SNES batteries were like SMS batteries...

[GohanX]

How are SMS batteries? I've never taken one apart.

Thanks JKM. just ordered a bit and some batteries from that site. I recall seeing a video with a guy using that same battery, all i have to do is cut the tabs a bit so there is a point at the end, then i should be good to go

[GohanX]

That site isn't the cheapest to get these parts from, but they are reliable and shipping is fast.

Hmm... I may not know what I'm talking about here. I seem to remember performing a carefree SMS battery swap, but I just opened Ultima and Phantasy Star and their batteries are rather attached to their brackets. Sorry.

Can these be used for the TennoKoe Bank cards? The built in tabs would make it a breeze to install.

I just use normal 2032 batteries. I coil a decent chunk of the exposed area of the wires at the end, so there's plenty exposed wire available where they need to touch the coins, then tight wrap it it all with electrical tape. Solder the other end of the wires to the cart after I've removed the original battery, close it all up and I'm done. I've never had one loose a connection, but I also wrap damn tight. I buy about 16 CR2032 batteries for the price of one on that link above.

Where do you get 2032s so cheap? f*ckers are like $3 each here.

Ebay.
5 CR2032 for $1.43 shipped.

Those may be cheap, but they have an expiration date of within the next year or so, compared to the more expensive ones that have a shelf life of 5+ years.

I buy mine at Big Lots currently. I haven't had any die on me yet. Battery life can depend on multiple factors, including the temperature they are being stored and used at. Most coin batteries should on average last 5 years on normal use, but I mean, I have had them last 10 also. At any rate, I don't trust the life times stated by any manufacturer, as most are not going to replace a battery for free 2 years down the road if it has died. Much like light bulbs, you really just never know.

This is indeed the best way to replace a game save battery.  Anything that doesn't involve soldering a new battery is not something I would want to risk with my game saves.  For someone without soldering experience, there really isn't a good (proper) way that is also easy.

The best place I have found to get high quality replacement batteries is from Digi-Key.  They need one leg cut in half to fit in SNES/NES solder holes. Unfortunately, I don't think any better fitting batteries are still in production.
