    Now after many years, how are the Roadster batteries holding up and what is the mileage on them?

    Clocks just turned over at 73k, battery in standard charge mode gives 170 miles, in range mode a little over 200. Real world driving gives me about 120miles (mostly sitting in the upper 80s :D, on highways). Roadster is a 2011 model. 3.0 battery upgrade due sometime...o_O

    Tom Saxton did a very nice survey for Plug In America, the primary conclusion of which was that the only significant factor effecting Roadster battery life was miles driven, and that the packs lost about 3.7 ideal miles of range/10K miles driven. Now, he did this in 2013, so maybe things have changed since.

    My 2010 2.0 seems to be ok. 43k miles, CAC reported to be about 141.9. Charges to 167 miles Standard, 214 Range mode, so I think I'm on the lower side of the range life envelope, but still within reason.

    Want to get the 3.0 battery, but dislike the thought of recycling a perfectly good original...

    My first early 2011 2.5 had an average CAC of 142; 170 in Standard Mode, 222 in Range Mode. Had 38k miles.
    My current late 2011 2.5 has an average CAC of 152; 181 in Standard Mode, 230 in Range Mode. Currently 15k miles.
    A friend's 2008 1.5 Signature 100 has an average CAC of 141. 169 in Standard Mode, 219 in Range Mode. Currently 23k miles.

    All three cars are on their original batteries.

    These cars have exceptional battery life, and they seem to maintain it extremely well when charged and cared for correctly.

    More than 100000 miles on my one.

    CAC is about 120

    I can drive a bit more than 124 miles (200 km) in standard mode in current winter conditions
    In summer I reached more than 186 miles (300 km) in range
