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

Ohm is a 6-pound drop-in replacement for your car battery. What's not to like about what it claims to deliver. It never needs jump-starting. Works on the coldest days (in temperatures as low as -40C). Lasts more than twice than lead-acid batteries, which go for three years. Here, you are looking at a 7-year average lifetime. No lead, no acid. When Ohm says it is a drop-in replacement they mean that it is installed in the same way.

The site says to "remove the positive and negative leads from your old battery, drop in Ohm, and reattach the lead to Ohm (red/positive lead first to prevent sparking)."

Also, Ohm is "smart" enough to prevent accidental draining if the driver forgets to turn off the lights. It can automatically turn itself off when critically low and switch back on when the driver starts the car.

How it works: There is a "burst of energy" for starting the engine which comes from a bank of supercapacitors. When the engine is not running, the supercapacitors are kept charged by a small array of batteries.

As for materials the company said its supercapacitors are mostly carbon. The batteries are LiFePO4 (lithium iron phosphate.)

As for dimensions, Ohm's are 9.0"x6.8"x6.8", and will fit Group 35 batteries. "It will also fit in most cars above Group 35, but may require some extra fixturing, " according to the site.

When will you see Ohm in the marketplace? Not yet. Greg Kumparak, an editor at TechCrunch, reported that Ohm is in private beta testing and they plan to roll out a crowdfunding campaign in the next month or so. The website, meanwhile, said they plan to ship Ohm early to mid-2016.

Kumparak of TechCrunch addressed the question of price. He said he was told by the company that they aim for a price point of around $200. Kumparak said that would put it "on the high end of what you'd normally pay for a battery ($120-$180) if you wandered into your local auto parts store."

Nonetheless, viewers might find the pricing amenable considering how long it lasts and some other benefits."Conventional car batteries contain dangerous acid and are responsible for over 24 million pounds of environmental lead contamination each year. Ohm has no lead, no acid, and is safe for the environment." Another promotion point being highlighted by Ohm is its light weight. "It's the easiest, most affordable way to instantly drop 30 pounds or more from your curb weight by switching from a lead-acid battery."

I was trying to figure out how resistors could be made to hold a large charge.

I design in supercapacitors (actually, they're called electric double-layer capacitors) in my company's products.

They can put out many, many amps for short periods of time.

I've been wondering when they would be combined with Lithium or LiPoFe batteries to create a replacement for a car battery.

This is a good development.

I’m sure it would run the 1500 watt inverter and the 12000lb winch in my Jeep just fine. I’ll stick to my Optima yellow top.

Yeah, it's not designed for heavy loads for minutes or hours at a time. You will need a lead-acid battery to run that winch.

a survey of people not buying the Ohm will be a measure of resistance

What is the amp hour rating, cold cranking amps, sustained cranking ability, ability to run accessories, etc..

Great a battery that shuts its self off causing your ECM to have to rerun readiness tests.

This is a good idea. A battery’s main purpose is to start the car. Then there is enough energy to run the radio, lights, computer, etc. This appears to be superior to lead/acid in that respect.

There are small backup batteries within it it for that very purpose, I assume.............

Ohm My God, we must resist.

Kidding. I welcome improved battery news.

What happens when those batteries go bad?

It's turtles all the way down.

Negative first off , negative last on. Safety reasons.

They should have named it “ONE SHOT.” For, you only get one shot at starting your car and then you are SCREWED!

Another “benefit” of having this piece of crap is that if your alternator stops generating you aren’t going far down the road. If it happens at night you are really, really SCREWED!
