I've wondered for years why people always gravitate towards Li-Ion cells when talking about a home storage battery. Li-Ion's advantages are far, far less important for a dwelling. Weight doesn't matter... you won't be moving them. Size doesn't matter nearly as much as it does in a vehicle... losing a few inches off an entire wall in a garage won't really be an issue for most people. Edison cells are incredibly durable and much, much more environmentally friendly than any other battery tech I know of. The lifespan is nothing short of incredible too... you won't need to change them out.

Thank you very much for the 2nd link. I was unaware any company was still manufacturing them. The last time I looked, the last company I could find that made them stopped a few years prior. I'm glad someone is making them still/again and marketing for an appropriate use.

The one odd thing is the price... for something as low-tech (relatively speaking) as an Edison cell, I'd expect them to be much cheaper. Must be the lack of competition.

They may seem to be low tech but the electrodes are works of art and manufacturing them is a lot more expensive than a lead-acid battery of comparable capacity. They charge slower too, but they'll stand up to abuse better than every other rechargeable battery tech. I looked at them for a long time before settling on regular lead-acid, cost and finding an inverter that would charge these properly were the major factors.
