My son is on his second leaf
My son is on his second leaf - the first was a 2013
lease - he turned it in at 36 months- second he purchased used. is now 5 years old and just about to the third lost bar. To maintain battery life he no longer fully discharges nor fully charges his leaf other than if it is absolutely needed. The leaf is only used minimally during the week taking kids to school etc. and he keeps it at about 50% charge and almost never lets it get to 100% charge unless he is going to drive it immediately. (and he NEVER fast charges it) He has level one and level two chargers in garage the max being a 6.6 KW.
He also has an e Fiat that is used by his wife as her daily driver she drives 51 miles each way and is able to charge at work. She charges at work with a level one until about 2pm them switches to a level 2 till 5pm - is timed so that it is driven almost immediately after the full charge is achieved.They do something similar in the evening - but she leaves for work with each am with about an 80% charge.She is able to do this as she does not use ac in the am plus drive to work has a drop in elevation.The Fiat is now at about 70
% capacity. He bought both of these e cars for around $8000 to $9000 dollars and pretty much driving them for close to free as he charges at around 6 cents per KW.
He still loves the leaf and tells me he will buy a replacement battery when battery will no longer support their needs.
After seeing his experience with the leafs I purchased a 2015 chevy volt new in Oct of 2015. I now have 35000 miles on it with no noticeable battery range loss. Love the car , I have had one program fix (in 3 1/2 year) by the dealer as car would not charge Now have received a recall notice re. battery voltage issue where car may shut down if a cell voltage drops too low. Have yet to have that done. I have a level one and a level 2 (3.2KW) charger in garage - went for one year using level one but now with level 2 have stopped using the level 1.
All in all a learning experience for both of us.
