Hi all!
Considering ordering a battery holder to supplement the built in battery on an X’s and O’s and I’m wondering if this is the appropriate replacement? Also, Which side of the battery is positive and what side is negative? I have put remote batteries on System 6 Williams games, but have not done so on an Earlier solid state Bally. Thanks!

Unfortunately, I don’t feel entirely comfortable installing one! Sorry! I would be fine with just doing the remote battery. Do you know how to go about doing a remote battery on a Bally? Like which side is positive or negative?
If you insist, look on the board with J5 on the top. The right hand side of where the battery is soldered is the negative side of the battery, and the positive side is on the left.
The negative side can also be identified as the side where it connects to the ground on the circuit board.
To remove the battery, use wire cutters and cut it off, or using a soldering iron, remove the solder on each side.
If there’s corrosion on the board from the battery leaking, just replacing the battery is not the last step. You have to have the corrosion removed and any damage repaired.
Note that after changing the battery, you will have to reprogram the machine, and change the batteries on an annual basis. Another option is to run long wires and put the holder near the coin door so you don’t have to remove the Backglass to change batteries.

Wonderful! Thank you so much. That is a tremendous amount of help. One day I’ll learn install a NVRAM, but this will work for now. The customer I am helping is very good with replacing batteries annually.

As mentioned, the chip is socketed, which means removing the old chip with a flathead screwdriver or chip puller, and installing the new NVRAM.

Plug'n'play installation. Doesn't get easier than this.
pinitech is currently out of stock, but Weebly is a great place and where I order all of my boards etc if he has them.

Ohhh, gotcha that looks super easy. I will definitely have to try it one day. Thanks!
Billc479 So, if I can remember correctly the battery is located near the bottom of the board right?
Quoted from Billc479:Correct. It is white tube with flat steel soldered into the board
Perfect, thanks so much
