Had a max rated range of 146 miles when I received it in 2013. Dropped to 140 miles in 2014 after a software update. Dropped to 133 miles in 2015 after a software update. Dropped to 130 miles last week for an unknown reason. That's not very encouraging. I do everything I can to keep the battery...

The objective of cell balancing is to keep every cell at the same voltage level. Being so, you can balance the cells to 3.9 Volt if you want to. It is not an actual recommendation if you want to optimize lifetime of your battery (always better to balance at 100% SOC), but it is much better than...

I really feel like Tesla made it really simple and limited the charge to 68%. Since the margin is low for the S40, I guess they did not invest a lot of engineering time on the battery re-programming. If the cells normally charge from 3.0 to 4.1V (as an example) and the algorithm for capacity...

I did not say that I ordered it after I learned this. My reservation was placed 12 months before. When I learned I would get an heavier battery with the same capacity, I was not happy about it and I called customer service. This is when they told me about REDUCED degradation. If the actual...

No, are you kidding me?! Did they really spoke about artificial degradation?? Can't believe it! Tesla sold me this S40 saying it would experience a REDUCED rate of degradation!! Didn't you also hear that from TM when you purchased it ? I keep the car charged at 50% to take care of the battery...

Noticed the exact same behavior of my S40 when I upgraded to 2.4.239 June 7th. My rated range dropped from 140 to 133 miles. With this 20 kWh buffer we have, I can't believe this is degradation. I feel like Tesla is artificially dropping my range to convince me to purchase the whole battery! I...

Got a 40 kWh and lost 8 miles on June 7th after a software update. When fully charged, I had a range of 141 and it dropped to 133. This is really annoying since Tesla told me this battery would have a slower degradation rate! I had 146 miles when I received it on May 2013.
