Hey everyone! I'm Hunter, one of the cofounders of Ohm. Let me know if I can answer any questions.
I have no idea if this ends up being a significant number, but I think the average driver spends somewhere around $10k in fuel over the expected lifetime of this battery; if cutting down the weight by 1-2% reduces fuel consumption by a comparable amount then Ohm would pay for itself.
(1) Those nasty things inside car batteries are easily recycled and in fact are recycled more often than not (like 95%+) (2) Car batteries do not last only 3-4 years as per the OP. Car batteries can last decades. There are many variables, but the car in my battery is far older than 4 years. (lol) (3) Replacing an easily-recyclable product with a less-recyclable one is no step forwards. (4) XX addressed by OP comment,…
>if it’s ever about to reach the point that it’ll no longer be able to start your car, it’ll just turn itself off. Your lights will fade out and the radio will go quiet Hope you don't plan on selling in the US because this behavior is going to get you sued into oblivion by the family of whoever ends up dead because the lights turned off abruptly on a vehicle with a faulty charging system.
Earlier quoted context omitted.
You're right! Lead acid car batteries are one of the great recycling success stories. What's interesting is that the volume of lead acid car batteries in the world is so high, that even at that high recycling rate, that still leaves 24 million pounds of lead each year from car batteries that don't get recycled. There's also been some problems recently with lead recycling plants contaminating the environment [1]. You'…
Some thoughts: The price point is impressive if you can sell at only ~$50 more than a standard lead-acid battery. If pressed to find a flaw, I think the biggest is one you've already identified: There’s one: you can’t run your lights and/or stereo as long with your engine turned off. Ohm’s battery reserve comes in at 10 amp hours; most lead-acid car batteries come in at about 45 amp hours. If you can run your stereo…
Probably your battery is near dead.
Also F150 pickup trucks are about $60K when loaded with options. Those guys are free spenders compared to commuter car drivers.

You're probably getting downvoted because a c*4 discharge rate implies over 3 kilowatts continuous draw, which is rather unlikely. Probably your battery is near dead. Also F150 pickup trucks are about $60K when loaded with options. Those guys are free spenders compared to commuter car drivers.
The accessory draw is enough to lower the (indicated) terminal voltage from about 12.6 volts to about 12.0 in 15-30 minutes, depending on what accessories are actually turned on.
Hey everyone! I'm Hunter, one of the cofounders of Ohm. Let me know if I can answer any questions.
Have you calculated how much money a typical driver would save in fuel due to losing 34 lbs of weight? I have no idea if this ends up being a significant number, but I think the average driver spends somewhere around $10k in fuel over the expected lifetime of this battery; if cutting down the weight by 1-2% reduces fuel consumption by a comparable amount then Ohm would pay for itself.

They are always looking to shave off weight so it can be redistributed in the way they want. Being able to cut 30lbs would be a big deal.
This is cool. Rarely in such established industries do people step back and reconsider the actual product requirements in such a practical way. Car batteries serve two TOTALLY distinct purposes (starting engine and running electronics), and this is a great solution for those. I'd be worried about the impact of rapidly increasing electrification (including hybrids) on the high end market (the most likely consumers for…
