Should I use a battery tender?

So I don't drive far to work each day (about six miles one way) and was told by dealer ship it would be ideal to run a battery tender on the car each night to help the battery. I'm getting the stock battery replaced (lasted a little over four years) on Monday and trying to make sure I take the appropriate steps. Just want to make sure this is necessary or any input.

Thanks!

I have the same issue. I had the high discharge on both BMW's the reports show 90% of all trips are below 5km. I put the cars on the tender once a week and it has made the warnings disappear

I'm currently still on the stock battery. Had a low voltage warning before (didn't start the car for two months) and hooked it up to a battery tender for 24 hours. Message went away for good.

I'd get a battery tender and charge it once a week (overnight would be great).
