Replacement battery for my Nextbase 122 dashcam has two wires

[colingcp]

I have ordered from Nextbase a replacement battery for my Nextbase 122 dash cam. The new battery only has two wires Black and red but on opening, the one that I am replacing has three wire, black, red and yellow.
Is the yellow wire obsolete or do I need another battery. I did specify the correct model when ordering and all utube videos showing refitting only seem to show two wires. Any assistance will be welcome
Thank you
