Seems like some will even chuck a perfectly good battery to get that "special" battery. I have been driving and fixing my own cars for 40 years, and can tell you that the need to get that "best" battery is over with the Leaf.
I agree with that.

As LeftieBiker said, that's a big "if". The charging system in the LEAF has all of the capability to properly maintain the battery, but the programming is lacking. As you say, the demands on the LEAF's battery are minimal. As such, we should see superior battery life to normal ICE chargers. Unfortunately, many have failed after only two years.

Exactly! Unfortunately, with the built-in charger, for many applications the LEAF battery will spend its life at about 60% SOC if not attended to by its owner.

Eight years is normal for my vehicles, too. But frankly, most of my other vehicles require NO additional effort on my part to achieve this amount of battery life.

That's where I get mine. Recently Costco has offered the best combination of cost/warranty. About $73 for a LEAF-suitable battery with a great warranty.
To keep your battery in top shape, I suggest the following:
Wire this solar battery charger to the car and place it with double sided sticky tape on the dashboard. It will keep the battery at 100% even after MONTHS of car non-use. I have 4 cars, and always get them to start.http://www.harborfreight.com/15-watt-so ... 68692.html
My LEAF already has a built-in PV module to maintain the 12V battery. It is insufficient to do the job, however, since the car is usually parked in the garage.

That's the best advice for a LEAF owner, IMO.
Every 6 months, to keep your peace of mind that your battery is still "strong" and holds a good charge (e.g., your battery is still good), use the battery meter below. It will put an electrical load on the battery and tell you if the battery itself is "good". http://www.harborfreight.com/automotive ... -9193.html
Someday, after 6-8 years (or even 10 years in my experience), it will give your a "weak" reading, and then you go to Walmart or Costco and get another cheap battery.
Also good advice. Another simple test is to simply let your LEAF sit for a day with the hood up after a full trickle charge (don't open the doors during this period). If the voltage is below 12V after one day, then you are in serious need of a new battery.

Very good advice! Thanks!
