Ohm is a drop in replacement for your car battery

Never needs jump-starting

Ohm is smart enough to keep you from accidentally draining your battery if you forget to turn your lights off. It will automatically turn itself off when it gets critically low, and then switch itself back on when you go to start your car. No more getting stranded with a dead battery.

Works on the coldest days

Unlike lead-acid or lithium-ion batteries, Ohm loves the cold. Have confidence your car will start no matter what.

Long lasting

Lead-acid batteries last three years on average. Ohm lasts more than twice that.

Ultra lightweight

Six pounds. That's how much Ohm weighs. 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.

Kind to Mother Nature

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.

A bank of supercapacitors provides a burst of energy to start the engine

A small battery keeps the supercapacitors charged when the engine isn't running.

Intelligent electronics ensure continuous and optimal performance.
