Hello. I am new to the group as of this post. I just purchased a very used 2011 Leaf, with a very degraded battery with a tested 55 mile range in eco mode and not over 35 mph. It dropped considerably at 62 mph driving a similar distance. But I knew this going in since I paid a fraction of what other cars with 37,000 miles cost, ICE or Electric. From what I have seen these Li-ion batteries are comprised of multiple cells linked together, not manufactured as a single unit. If this is in fact true, why can we not remove and inspect each cell, discard those below a certain value and replace them rather than let the re-builder do essentially this, and then sell/lease us a non new battery for an extortionist price? Sure you can seriously fry your ass off but I've worked in much higher power/amperage in old building demolition from the turn of the last century, and with care and understanding it can't be that bad. Has anyone disassembled one of these Leaf batteries to verify if this is possible? Also I'd like to add that I like the car from a calm, quiet perspective and the slightly taller seating position seems good too. Mine is SV I believe and has a reasonably good sound system, Navigation and backup cam. The last owner has mismatched tires on it, some low rolling resistance, some not but it's still smooth and quiet. So I plan on keeping this one on the road for quite some time.
