Does a new battery need "conditioning"?

Does a new battery need "conditioning"?

A while back it was mentioned (in this thread: that a new battery should perhaps be charged to full range the first couple of times in order to condition it. Can anyone provide a reference for that assertion?

I'm noticing that my car is charging at a maximum of 24 miles per hour of charge even though my NEMA 14-50 outlet is delivering pretty much the full 40 amps at 240 volts, and even when I begin charging the battery from a fairly depleted state (started at about 30 miles of range, and checked the charging rate again at about 100 miles of range). I am also ending up with only about 230 miles of range after a standard charge. So I'm wondering whether this is because I've had the car only a few days, and whether it would help to do a couple of full range charges.

I'm about to embark on a road trip, and I'd like to have as much range available as possible, and to have charging times as short as possible.

standard mode is not charging to full, so if you'll change mode you will see something as 265 instead 230.

@Jolinar - Right, but shouldn't I also be seeing 240 rather than 230 for standard mode?

I'm seeing the same numbers. Multiple overnight charges at 240/40 end with a range of about 237 miles. Changing to Full charge only raised that to 250 miles.

Are you in Rated or Ideal mode? In rated mode, it should say 265 for a Max Range charge. Ideal will show the 300 mile range you might expect from Max Range and I'm seeing 271-275 for Standard at a full charge right now.

I believe Rated mode is also based on your driving habits. So, if you're driving it a little harder than normal (which is to be expected with a fast new car), then I would expect to see a drop in range.

@timdorr, where do you see a setting for Rated vs Ideal mode? And the 271-275 that you are seeing, is that Ideal mode after a Standard charge?

I've got go take another look at that screen, because I didn't see any way to change the way mileage is displayed. Rated range is what is displayed in the middle of the instrument panel (beneath the speed on the speedometer), and Projected range is displayed at the right side of the Energy app graph. Is there something else?

NiMH needs "conditioning" because of its memory effect but NOT Lithium Ion. Tesla recommends against such "conditioning" as in depleting it or charging it to MAX RANGE because of prematurely degrading the battery.

By default, the software would charge your battery optimally. Just remember to plug in!
