Battery OEM Nissan or OEM Mazda

Our other car, the 2016 Leaf, kinda is the embodiment of all the negative talking points you hear about, since it's an older EV: It uses an outdated & slower charging standard, has a small battery, and has significant battery degradation (29%) since Nissan decided, in their infinite wisdom, to not give the Leaf a coolant loop for the batteries. (Heat is the biggest killer for EV batteries).

Problem I have with my 2016 is I go threw lot of batterys , first one lasted 3 years which told it comes with 3 year battery 2 one lasted 2 years ,The third one only one year..So brought to dealer. They checked connections and hooked up meter left hooked up for 2 days..It draws .07 amps when just sitting.

So far have not had any issues except for dud OEM battery, kriginal and warranty...
