The original Japanese battery on my 2012 SL lasted 7 years and died relatively quickly after that. Replaced with Costco’s Interstate 51R battery for $80. Fit perfectly, works perfectly, very good warranty, expect it to work until I scrap the LEAF. For a vehicle that only goes 35 or so miles, no need to spend bigger bucks on a new 12V.
