I bought a motherboard with a dead RTC battery, and it would not store any change except for date and time.
M/b is a rebranded (?) PcChips M530 (that is for sure as the BIOS matches + pics are identical).
After researching on the internet I came up with nothing.
But, after close observation, I noticed that I could see the chip's pins (with 0.45V) and finding that it is in fact a plastic cap (with a rebrand markings) on top of a VIA VT82885N, plus a BR1225 battery soldered the the legs of pins 4 and 8.
The cap can be easily removed with a screwdriver on aither of the short sides.
As with the Dallas battery hack pins 4 (-) and 8 (+) you just solder a CR2032 on it and you are good to go.
In the original PcChips pics the RTC is a Dallas, making unsure if it is actually compatible with any of those RTC or just Via, but see note at the bottom.

Basically if a Via 82885N works than a 82887 should work too; Dallas could be an option if no Via chip is available.
