Questions about this item

Does the CR1220 CMOS battery generate any heat or noise while powering the BIOS clock all day?

The CR1220 is a passive 3 V coin cell with no moving parts, so it produces no audible noise and negligible heat during continuous operation.

What connector must the laptop already have for this two-wire battery to plug in directly?

The battery uses a standard two-pin regular connector, so the motherboard must provide a matching two-pin header for a direct fit.

Will this CR1220 pack work in an older MSI GS75 or Asus Q302L that still has the original CMOS socket?

Yes, the CR1220 chemistry and two-pin connector match the original specification for both the MSI GS75 and Asus Q302L models.
