Six temp bars isn't bad, but it's the upper limit of 'acceptable' for a Leaf battery for any length of time.

Ideally, in a cool climate strive to keep the battery at 6 temperature bars or lower. It is not feasible in a hot climate, but 2015 battery seemed to tolerate the Phoenix heat fairly well. The batteries in my cars spend (spent) a lot of time well above 6 temperature bars (center of the scale). A 9-capacity bar 2015 would be a good choice since I doubt rasgaroo's climate is as hot as mine. Even an 8-bar car would probably give rasgaroo the necessary range for 4 or 5 years.

I'm actually considering selling my 8-bar 2012; PM me if you want to see the listing. It does 30-40 mile trips with no issues, even at 75 mph.

If it has the original 2012 battery or a replacement of original type from Japan, it will not stand the heat. My 2011 was down to 10 bars after 1 year and 8 bars a year later (8 bars after only 2 years of use). The replacement battery was down to 11 bars a little over a year after installation. 2012 used the same battery type. The 2015 did much better in the same climate with similar use.

I've also heard that if you only ever charge your battery to around 40%, you can have a significantly longer battery life. Is there any truth to this claim?

Tests of other batteries show that keeping the state of charge close to 50% gives the best battery life. What to avoid is:
Long periods of time at high SOC... like over 80%
Going to low SOC. Regardless of how long... like under 30%

The mechanisms are different. 60% to 40% would be a fairly good cycle.

Get one that has double the most range you expect to drive and then NEVER NEVER NEVER charge it past 80% SOC.

That advice is a bit extreme. Charging to 100% right before starting a trip isn't going to cause measurable damage to the battery, especially in weather that isn't really Hot.

As LeftieBiker said, Dave's advice about never charging beyond 80% is a little extreme. It is important to avoid leaving the car parked for extended time at high state of charge (SOC), but don't worry about charging to 100% if the car will be driven within a few hours. If the car will be parked for extended time such as at an airport, I recommend parking with SOC ranging between 40% and 70%. It is a good idea to pick a car that has significantly more range than you routinely need so that the range is still adequate when the battery gets old, but double your daily needs is more conservative than necessary.

With "double the most range" there is NO reason to charge to 100%.

The only reason I said double was to discount winter explanations. He mentions what? 25 miles is longest trip he might take? He uses other options for anything greater. So sorry, no need to charge to full.
