We know CHARGING in Range mode isn’t the best for the battery and shouldn't be done very often. What is the downside to using Range Mode to DRIVE as far as battery longevity? I recently needed to squeeze as much mileage out of the Roadster as possible to get to and from South Haven, MI and Chicago (~125 miles each way) in about 24 hours (add on 20 miles for stops and a little tooling around). My biggest problem, I knew when arriving in South Haven, I only had a 110V 15A to charge with. And it was just a quick overnight so I was only going to have ~14 hours to charge. Those with their spreadsheets out already know I had a tall order in front of me! So I charged to absolute maximum before leaving Chicago (including about 2 hours of “top off”) and had ~230 ideal miles (on my 26K #1190) in Range mode. It was a little spooky taking off b/c regen was deactivated (for obvious reasons). That car will REALLY roll with no regen. Anywho, We arrived in South Haven just fine with about 70 miles ideal left in “Range” (we made a couple stops and I drove non-conservatively, but NOT aggressively). Again, the whole trip was done in Range (and very little no drafting). I switched to “Regular” mode to charge the vehicle and ideal miles plummeted to around 40 or so (don’t remember exactly). Then charged for 14 hours. In the morning, it said I only had 110 miles on the charge. I was obviously a little perturbed (again, trip back with no stops is 125 miles). I clicked it into Range mode to drive and that went up to 145 – feeling a little better. But on the dash, it said I had 120 miles. Very WORRIED again (do you tell the GF and freak her out? I mentioned it softly and she took it OK and said that if I wasn't worried, she wasn't worried. OK - cool!). So I drove very conservatively including drafting on the way back. As the ideal miles on the console began to bleed, the dash stayed at 120 for about 20 mins! I was delighted. My GF had the GPS going and kept reading down the lower and lower mileage home as my dash continued to sit at 120. Finally, the console started catching up with the dash and they both started to bleed. We made it home with zero issues (I drafted about 90% of the time behind a truck and went about 65 MPH the whole way). When we arrived home, the console and dash said 25 ideal miles left. I was thrilled! I dropped of the GF at the foot of my building to walk the pooch (who came with us for the trip) and clicked the console monitor to change it back to “Normal” range. The fan BURST into action behind me and I get this warning on the console that I have 2 miles to go and the car is going to shut off! I was pretty darn scared! I still needed to get the car up to the 5[SUP]th[/SUP] floor of the parking garage in my building and obviously, this is all uphill! That’d be ALL I’d need is a flatbed right on front of my condo building with my pretty toy sitting on it for the neighbors to laugh at! I switched it back to “Range” and the fan settled down and I quickly zipped it up the ramp and to my space and stared charging immediately. Crisis averted! I’m now charging in “Storage” mode b/c I’m going to be away from the car for the next 17 days **sniffle** and I hope it’s not too upset with me when I get back (at which point I’m going to bump it up to “Normal” and let it fully charge and I’ll take it out about 48 hours later). So, again, did driving in Range mode for this sequence put a hurt on my battery – at all?
