Hi guys! i'm asking for a little bit of advice since there is a battery involved here and i don't want to do something stupid. I got an older machine which uses SRAM and has a soldered in 3.6v battery, the problem is after about 10 minutes of being powered off the machine would lose its memory despite having a new battery.
I opened it and found the pad to the battery was lifted. It must have had just enough contact to let the battery keep it charged within a minute or two of being powered off.
Looking at the circuit, the side with the lifted pad (negative) connects on the PCB to a nearby transistor(?) while the positive side connects to a nearby resistor.
Is it safe to directly wire the leg of the battery to these two components the PCB connects them to? I don't like to do something so hacky, but i am afraid i don't have much other option.
I've attached a photo of the pcb from the top side as well as clips from the service manual of the relevant parts of the schematics
Thanks in advance!!!
