I got a 486 motheboard recently that has sixe 1/2 AA 3.6V lithium barrel battery so there is no any leakage at least yet. The battery is non rechargeable and seems to be glued to the motherboard in addition to being soldered to it. When the system is turned on multimeter shows 3.7V at the terminals but when the system is turned off the voltage at terminals gradually goes down and I have measured only 0.6V the next day. For some reason the system seems to be still keeping the bios settings. I know the battery must be very old since the voltage goes that low when system is turned off. It says it is non rechargeable but I wonder if it is recharging it since the voltage goes up when the system is turned off.
Main question is that would it be safe to leave the battery on the motherboard? I know that lithium batteries dont often leak but I also know that they can be rather volatile in some circumstances. The motherboard itself looks very pristine like it has not been used much and I dont see any corrosion anywhere. I know that if I solder a new battery there it is not going to look as pristine anymore and not sure how hard it is to remove all that glue that is used to glue to battery there.
