Bravo, nice work. I love pictures. The internets needs more walk through with photos.
Just decided to Try my hand at replacing the battery of my New generation cart.
Lo and behold it looks like someone already modded the PCB with a type of holder.
Best part is, now All I have to do to change the battery is power on, and swap out. No more work required.
Will it? Do they always leak, or leak with high probability? It can be safely removed now, I suppose... the problem is it's welded to the steel prongs attached to the security cart. Not so easy to remove.
My battery looked the same as the pics above except there were no wires on the back of my security PCB.
Would this battery be suitable to act as a helper battery? http://www.atbatt.com/product/21208.asp
it has the 3.6v and is a full size AA battery instead of the 1/2AA size on the CPS3 carts.
Ive been swapping cps3 batteries for a while now..i must say i prefer doing them while the game is running....but congrats on your success!!
Its the only safe way as the cart can detect voltage fluctuations why on battery power and can kill itself.
Are you saying the "safest" way for the battery to be swapped out is when the it is powered up? That sounds a little scary and kinda awkward to do.
No when on mobo power the battery is not connected to the circuit. As far as trying to change a battery on a powered up pcb, if your not comfortable around electronic devices then yes it can be a scary proposition to a novice. When I say safest I am speaking from the point of view of the cart not dying 2 weeks later as a result of its security design not from the physically changing the battery perspective.
But since the CPU on the cart can detect tampering through substantial voltage fluctuations such as a spike when using helper batteries and the slight voltage difference between the old and new battery it has a high 80 percent chance of EVENTUALLY killing itself so the power up method is the best way to go. Basically I am guessing it has a comparator circuit on the battery when the game is off and the battery is in use, so if you change the battery when the game is on and the battery is off your cart stands greater chance of not dying two weeks after you changed the battery.

Has this been confirmed? I ask because these kind of myths seem to come from nowhere and somehow stay around. Take CPS2 for example, people always said removing the battery will instantly kill the game. It was not until I actually purposely removed a battery to kill a board that the myth was put to bed. I'm not saying your wrong and I understand that removing the battery from CPS3 will kill the cart instantly unlike CPS2. I just question if there is a security circuit to check voltage that will kick in a week or so after the change. For me I would more guess the weak link in CPS3 is while connecting the cart to the mobo, we all know how MVS / AES games can be in this area so can't a improperly inserted CPS3 cart kill it and be a reason instead?
