Would that be the one to remove for VA0 motherboards?

yes, but on VA0 it can be done easier, remove R2 on the controller boardchôkai wrote:Would that be the one to remove for VA0 motherboards?
though removing R612 would work too

Re: Clock Battery Mod CR2032
To be clear, on va0, if I leave R2 off the controller board without adding the diode, the battery won't charge? If so, that solves 2 things for me, as I was looking for a replacement, but if leaving it off stops charging, I'll leave it out and not worry about a rechargable battery.

That's right, just remove R2 and the battery won't charge. no need to install any diodesMetroidTalon wrote:To be clear, on va0, if I leave R2 off the controller board without adding the diode, the battery won't charge?

Re: Clock Battery Mod CR2032
Thanks for this information.
Without the R612 I was expecting to measure 0V on the battery circuit, but I've measured a little bit less than 200mV trying to charge the battery. Is this a problem for non-rechargeable batteries?
After the console stays on for a few minutes without the R612, it seems the 200mV goes down to almost 0V.
I have a VA1 PAL console.
Although I got those measurements, I still continued to make the mod, because maybe the 200mV at the start won't hurt non-rechargeable batteries. If it hurts non-rechargeable batteries, I'll just use rechargeable batteries.
I like to make all my mods reversible, so I removed the R612 and saved it in storage.
I then soldered wires to the pads of the R612, and soldered three 390 Ohms resistors in parallel and a button in series to the wires. I can now turn on/off the recharging of the battery.
I'm mostly going to use two AA or AAA batteries (I've placed them outside the console, it's not pretty but I won't risk leaking them inside the console).
