    Best before date on a battery?

    Hello, I am in need of a replacement tyre pressure sensor and the below is a bargain price for a OEM part, the best before date on the packaging says 21.01.21, I'm assuming this is the date it should be fitted by right? It contains a lithium battery. Thanks Lewis

    I have 2:30 amp relays running the door poppers for my shaved door handles. They only seem to work properly when the Vehicle is running. Is this an alternator a battery relay or perhaps a wiring problem?
