Only one correction.

Either way you can order the new LY battery, since it’s manufacturing date is newer and there’s been some fix in it.

You just use a toothpick to take down both old and new switches, and mount the old switch on new battery. Takes 10 min and steady hands.

I just did it, and the things working….

Thanks for the guide.

I would not just order the LY battery. This depends on your manufacturing year. The LY battery has wires soldered onto it, but the old model does not have wires soldered onto it because there are contact points on the battery holder (like an old cell phone battery). Just open your mouse to be sure. Old model uses the L-L11 battery.

One tip: for the old model you don’t need to unscrew/remove the battery holder. Just take the battery out.

Pro Tip on reassembly: attach the ribbon cable from the upper shell before reinstalling the battery cage. The battery cage makes it extremely difficult to slide the ribbon back into the slot.

If you work carefully, it may be possible to skip disconnecting the ribbon and battery cage altogether.
