Uh NO.

Rechargeable batteries. have a "Minimum state of charge" now you can discharge PAST this point. but you should not because the overall life of the battery goes down much faster at lower State of Charge.

Tesla calculated this point for their batteries and programmed it in.

BUT.. in an emergency.. Well you do what you have to do and if another 10 or 15% of the state of charge makes the difference between the BATTERY dying a bit sooner than expected.. and YOU dying sooner than expected.... Well the battery is way, way, way easier to replace.


If I wanted to make more profit I would let you run the battery down so far you needed to replace it 2 or 3 times as often as I need to replace mine Tesla is not doing that.. Except in emergencies.

This is what I said many posts ago and I agree with your analysis.

I use Lithium Poly batteries in my model airplanes and have found this characteristic of lithium batteries to be true.

"Lithium ion batteries can be discharged below a design voltage but the battery may insure damage that may shorten the life of the battery.

Three things that can shorten the life of a lithium ion battery.

1. Very large discharge rates.
2. Very large charge rates.
3. Discharging below design voltage.

I suspect the added range was achieved by lowering the cut off voltage which as I previously stated may possibly result in a shorter battery life.

I also suspect Tessa will take care of the Tessa car owners if this does result in a shorter battery life. "

By this I mean Tesla took it on their own to help these people and I am almost sure Tesla will honor any warranty on the batteries.
