Battery OEM Chevrolet or OEM Subaru

The bolt (possibly the cheapest used EV available) batteries last well into the 200,000mi lifespan. My insurance lowered $80 when I bought my first EV. My state started charging an extra $150 to register an EV in 2019. About the same as the average ICE owner would pay in gas tax.

Generally speaking the ownership cost is low. I have had a 2013 Volt since new. I hardly ever need the engine to run, so it has had 6 oil changes in 12 years. I have done no other engine maintenance. It still has its original traction battery and is still performing well.

At 10 years and 330,000 kms my Volt battery didn't even show degradation.

Mine is ten years old. It's a Chevy volt so it's a small battery and has over 3000 cycles and done 130000 km. It's at 87% original capacity.

What is the sound of one hand clapping? Does a bear sh1t in the woods? If the bear does, is the turd a uniform size and power that will work with attributes of all the other different sized bears out there?

Replacing my battery recently

A new battery at 10k miles.

Battery died around 50k miles.

My 2020 Outback OEM battery only lasted 3-ish years.

The OEM Subaru battery does not have a lot of reserve power.
