Those who do will be Capacitive reactionaries....

There are Lithium batteries inside the box...................

Yeah especially if your car is garaged.

“When the engine is not running, the supercapacitors are kept charged by a small array of batteries. “

How often do you have to replace those batteries ?

[Red Badger]

Well, they’re inside it so their website says 7 years.......................

[Secret Agent Man]

And probably even harder to resist as time goes by.

I don’t believe it’s a deep cycle.

Yeah, I kinda thought they buried the lede; FreedomPoster nailed the initial market: cars with premium parts that would love the lighter ride.

Thanks. I was informed of that by one of my younger relatives, who knows more about batteries/electric motors than most of us.

[right way right]

The price is the only problem I see.
Conventional battery’s fail prematurely because of poor maintenance.
I have a factory one in my 04 Dodge all I have done is kept the terminal contact areas clean and drive the truck regularly.
We do have mild weather in Washington state (western) cold is 22°F Hot is 95°F that probably does help too.
Seems hard to justify paying double in my opinion.
I do like new technology and would buy one if they match prices with conventional batterys.

My Jeep battery lasted 11 years. My Savana battery lasted 11 years also. In Michigan. These cars were daily drivers, and I think that makes all the difference in the world. My boat batteries (27 series x 3), 5 - 7 years MAX.

"your car better be tuned up and start on the first try"

Ping to the top. Car batteries have TWO important ratings: Cold Cranking Amps (CCA) and also Reserve Capacity (RC) which relates to the total energy the battery will deliver. This "battery" may be able to deliver the CCA necessary for a single start, but will have a tiny fraction of the RC stored in a conventional lead acid battery.

Additionally, I live in the cold Midwest, and get seven to ten years on my car batteries, not the three years stated in the article. I consider a three year old battery "new". This may not be true in desert climates, but is sure the case for a large majority of the country.

Available now ?

Would be great for my old 88 Toyota 4x4 that gets used rarely these days shy of hunting, fishing and snow storms to plow the road to the house.....

Guess I could just retire, do more hunting and fishing and go wheeling all the time.......:o)

[antidisestablishment]

I’m just jealous—I love real, raw metal. The new cars look and run sweet, but nothing says American muscle like 50s and 60s.

[slouper]

You must be in the lead/acid car battery business, no? :)

Agree entirely. I've never heard of a battery being dead after 3 years.

Get a charger with a desulfation mode and bang it every year.

Sulfation is what kills batteries. The lead plates corrode into nothing.

My “Smart” brand charger has one.
