Cart battery replacement. Coin battery clips.

[Knuckle Duster]

So I'm looking at replacing batteries in NES SNES & Genesis carts.

I'm mainly worried about the genesis cart's internal space. Is there any recommended holders online that I should look at getting? I'm looking at ebay, and see 2 or 3 different types sold in bulk, different contact materals, but don't know what would work best.

Many of those battery holders are too tall. It's easier to just buy batteries with the solder tabs already attached, which is what is already in the cart.

Also, especially don't try to just solder in a standard battery. It's a huge pain in the ass to solder to most of them.
