Great advice, I opened my camera up following the linked video (remove ribbon cable, unscrew 4 screws in the corners, unscrew 2 more screws in the center, done) and noticed my battery was bulging slightly. Purchased a replacement from the exact seller on AliExpress linked, which arrived in the US in 10 days. Quick swap and my camera is like new, unplugging from power results in the 10 second countdown instead of dying immediately, and the date/time is not reset every time it shuts down.

I had even better success than the guy in the linked video, since it seems he bought a battery with the red and white cables reversed. The battery on AliExpress linked had the correct order.

Old battery and new battery, notice the identical ordering of the wires

How much did you pay for the battery thank you

Since I bought 2, roughly $2.74 each plus $7.50 shipping, for a total of $14 including tax. The link is right there in the original post by @Darnell, so you can check yourself.

Looking now, it seems to be $3.50 for 1 plus the same $7.50 shipping, so around $11 USD.
