Do you proactively swap your batteries?

[v_van8988]

So my 2019 G90 Ultimate is reaching 17,000 miles. This car was serviced around 2019 once, and it is still using the original battery. No issues yet but I'm thinking if I should swap it before any issues happen. Do dealers have a way to check the battery health? Thanks!

Most dealers can definitely check your battery's health during a service visit, they usually use a battery tester that measures voltage, cold cranking amps, and overall condition, your battery's original and over 3 years old, it's not a bad idea to get it tested before it starts causing trouble, really better safe than stranded

Isn't it kinda wild how dealers often wait for a no-start before suggesting a battery swap? Shouldn't we expect them to proactively check battery health during routine service, especially on luxury models like this?
