CEI Hot Shot

[Crash0]

I have a CEI Hotshot 20105 I have been working on for a friend. I got the reel issues sorted out, but now getting a battery error. I have replaced the battery, so I figure new battery is also is bad.
My question is, Is there a way to replace the smart battery with a more conventional type of slot battery?
I would really hate to order another that takes a month to get here, and possibly have same issue.

Yes, very likely.
Please post a picture of the original battery and tell us the voltage

I am getting error BA on either one

You probably purchased a pull out from China.
The problem with those modules is once it has been used in a board the battery is connected, it remains disconnected until it senses voltage on the board.
If it has ever been in a active board the battery has been connected and stays that way. Figure the battery in the module you purchased has been active (connected to the RAM chip) for about 15 years or more.

Yeah I just left the company a nastygram, 
I was kinda hoping there is another way to hook up a more common battery to be rid of the more than likely bad smart batteries

[Badbaud]

I used to design with those modules so have a couple that have not been activated.
You could send me the board and let me figure out a regular battery solution and if not I would drop in a fresh module.

I actually figured it out, Batt error gone. Used 2032 battery and holder, I'll post pics in a bit

1st pic is underside of battery, note the 2 pins that go from the chip to battery.
2nd is showing that I cut chip out and away from battery. Soldered 1 pin of the 2032 battery to the chip, and using a short jumper wire connected holder to other pin. just make sure + to + and - to -. Insert chip and battery in the board. making sure chip is facing the correct way. Power on and reset the error.
3rd pic of it installed on board. yeah it could be nicer but it works.

Since you've proven the idea works you could make it a cleaner mod by using some silicone adhesive (like Silastic or RTV3145, GE silicone 1, etc) to attach the battery holder to the bare space on the board, then run a couple of small jumper wires from the battery holder terminals to the solder pads on the board. But hey! it works, so good job.

I was thinking more along the lines of 3D printing something

[rokgpsman]

Let us know what you come up with, could help someone else that has a similar problem.

Anyone know what chip is used with those batteries?
Might make it simpler to design a new holder with fresh chips.

Probably need some tweaks, but won't know till I print one
