Ohm has worked up a drop-in replacement for car battery

You can get about 4 regular car batteries for that price. That’s like 12 yrs., longer if you live in a warmer climate.

I think I'll stick with the regular batteries for now.

[Grampa Dave]

Depending on the weight, if lighter than regular batteries, this could be a great battery for kayaks and small boats.

Lithium batteries used now cost $1200 and up.

If people like Porsche and Ferrari start using it, and they would if it’s a good product just for the weight savings on a performance car, then maybe it’s time to get one.

If God wanted us to have capacitors, he’d have miracled us some.

He crashed a spaceship in 1947 to give us transistors. They got this story about Bardeen and Brattain (made up names for aliens if I ever heard 2) at Bell Labs. Yeah! Right! ME 262s? 10 years later SR-71. It's aliens.

[SubMareener]

Las, it is really powered by pin ups ;-)

[Paladin2]

A 30 lb weight save is a big driver to get OEM placement.

[T-Bone Texan]

Agreed. We got lasers from aliens too.

[Paladin2]

Uh, Laz, these aren't capacitors, they are SUPER Capacitors.

Big difference....

[moose07]

Nice concept.
When the Japaneese manufacturers start fitting them on their home market cars it will be time to move.
(Thanks for the pings.)

Here, a local battery store gives $5 each for used car batteries.........................

Here's a reason why this battery may interest automakers: have you ever picked up a real car battery using lead acid cells filled with fluid? Those things are HEAVY. (I've picked up a brand-new Sears DieHard battery and that unit weighs well over 25 pounds).

I was wondering how often you need to feed the gerbils.

[Red Badger]

They ought to call them DieHEAVY......................

[DaxtonBrown]

Actually, my Bel Air Sedan is 3200 lbs. The new top of line Camaro is 3,702 to 4,374 lbs. My 67 Camaro convertible is 3,200 stock and I will be able to drop its weight by 300 lbs.

What kills the gas mileage most is the transmissions. I want to swap to the 7004 4 speed which will get my cars up around 16 mpg.

[Red Badger]

Lead has become increasing expensive over the last, oh say, 7 or so years...............I wonder why?...............................

Modern Civilization is based on the availability of TWO metals. One is GOLD, the other is LEAD................................

[VanDeKoik]

Might get one of these as a backup. Car batteries and Michigan winters don’t always get along.

[sportutegrl]

Since it is made by Ohm, it will be hard to resist.

[Red Badger]

Try electronic ignitions and a new Holley Economaster................

[Red Badger]

Oh, try just one Mho,,,,,,,,,,,,,,,,,,,,,

I recently replaced two 10 yr old batteries as they were not holding enough charge to do winter starting. Both were in VW Jetta TDI vehicles. I’m guessing that they did so well because they are large capacity to start with (glow plugs plus Diesel cranking needs), the charging system was well designed and it could be that the battery design was superior. Two out of two with the same life is not likely an outlier. YMMV
