First, thanks for all your contributions to this amazing resource. Newbie here...
My wife and I just (three days ago) purchased a used (certified pre-owned) 2013 Leaf SV with about 30,000 miles on it. Early '13 production date. We've been waiting literally years to get one in a pricing situation that made sense to us financially.
After three days of ownership, I'm starting to feel I've been suckered by the Nissan dealership. I ordered an OBD reader and have LeafSpy ready to go when it arrives, but don't / didn't have it when I bought the car the other day. ...
Okay, enough back story. Still waiting for the OBD reader to arrive, but the problem is that not enough kWh seem to be flowing into the car when we charge it. In other words, taking the difference between the existing energy in the car at the start of a charging session and the 80% at the end of a session (charging via a level II charger to 80% for increased battery life), the kWh numbers being added don't seem to indicate a battery anywhere near one with 85% capacity remaining.
Thoughts or advice? Anyone else have a similar issue with a CPO vehicle? I've written the CPO e-mail at Nissan and the next step is contact with (a sit-in demonstration outside...) the Nissan dealership if things continue to look suspicious. Any advice would be greatly appreciated. Our raw excitement at having finally gotten our hands on a Leaf is turning a little sour...
I would hold off on the sit-in, at least for now.
It is logical to think that battery capacity can be determined by amount needed to recharge from X% to Y%, but the SOC bars just aren't accurate enough. Others have suggested driving until turtle mode and then recharging to 100%, but I still don't think the results are worth the additional stress on the battery.
It is true that the only way to really know the condition of the battery is through LeafSpy. That is why everybody needs to be so thankful that Jim Polluck (Turbo3) wrote it and made it available at a reasonable price. It also has much additional functionality beyond battery health, as it can also monitor tire pressures, which is important too.
I too thought there was a problem with my replacement battery, I thought there might be a bad cell pair that was impacting the range as indicated on the GOM. But when I checked it with LeafSpy, it was well within the acceptable range.
Once the battery is checked, it will show a clearer picture. And ironically, it may be better news to have a poorer battery, as then the odds of getting it replaced under warranty by 2018 are much better. The LEAF will also need to be driven. The best situation in my opinion is if you're just about at 60K miles at just about 5 years, if you're hoping for a battery replacement.
