Changing SNES batteries

[kingjohn3]

I want to change all my batteries out seeing as they are all nearly 20 years old but I am not skilled with a soldering gun. Is there another option that's just as good

[kingjohn3]

Is this what I need or is there another/better option?

Not sure is that correct size as I think it should be 2025 (or something that area).

Those might work but as they are thinner they won't last as long.

Do i need to solder them or can i use electrical tape? Ill open a cart to see what size i need

[Arseen]

Very strong recomentation of soldering as then the connection will not be lost.

Lose connection -> lose saved game stuff.

If you stupidly end up going with the tape option, then don't buy batteries with legs as normal ones work better then as you can pry the old battery out of it's legs and then sandwich the new between them.

I would suggest that now is the time to learn how to solder.  Learn by practicing on a cheap sports game that has a save feature.  If you screw it up, you are only out a buck.

Soldering these is quite easy AS LONG AS YOU REMEMBER TO MINIMIZE THE HEATING OF THE BATTERY!!!

It had SNES in the title so I figured these were right.

not impossible, but so far I've only seen 2025 in snes cart, and 2016 in GB carts.
best bet is to open the carts and have a look

Like I said before I think the only difference is the thickness and thus the longevity is shorter.

Did some digging and these are the ones that are SNES size (2cm in diameter) with various thicknesses.
The thicker the more capacity thus lomger life for holding game save data.

Name    Capacity (mAH) size (in millimetres Diameter * Thickness)
CR2016        90                        20 × 1.6
CR2020                                  20 × 2    
CR2025      160–165                     20 × 2.5    
CR2032        225                       20 × 3.2

Got it!

I initially thought that the 2016 would be to small (in width) for the contact to reach the snes cart connector, but it seems that the 2016 I have are almost the same width as the 2025/2032:

Yellow circle is the CR2016 on top of the SNES cart battery.

Hmm.
Maybe SNES battery is actually CR2320, which means you should be able to fit CR2330 (265mAh) in there or maybe even CR 2354 (whopping 560mAh) for really long save realibily.

I don't have my SNES screwdriver at hand, so what does the original battery actually say?

This cart has CR2032 and is dated of June 92 ... still saving
