Powering the future with
sustainable graphene batteries

SETI POWER's Ceraceil technology represents the next generation of energy storage, combining the benefits of graphene and supercapacitors to deliver superior performance compared to traditional lithium and lead-acid batteries.

Why batteries die

Everything on this page rests on one idea.

A lithium cell stores energy by driving a chemical reaction, and that reaction is also what destroys it. Every cycle moves material that does not move back perfectly. Capacity fades, internal resistance climbs, and eventually the pack is replaced. That is not a defect — it is how the chemistry works.

SETI Power Packs use graphene-infused EDLC supercapacitor cells instead. Charge sits electrostatically on the enormous surface area of a graphene matrix. No reaction takes place, so there is no material to consume and no mechanism for the pack to degrade.

There is no lithium, no cobalt, no phosphate and no liquid electrolyte in a SETI Power Pack. There is also no thermal runaway pathway — not as a safety feature bolted on, but because the chemistry that causes it is absent. What is left is a pack that charges as fast as you can feed it, works from −20°F to 150°F without derating, needs no maintenance schedule, and is still the same pack in thirty years as the day it was installed.

Performance, in numbers

None of these are marketing numbers pulled to sound impressive. They fall out of the physics. A battery has a cycle count because each cycle consumes a little of it; take away the reaction and the cycle count stops being a countdown. It charges in minutes because there is no reaction to wait on. It works at −20°F because there is no electrolyte to thicken and no chemistry to slow down. It needs no maintenance because there is nothing inside it that changes.

The one number people query is the warranty, so it is worth being plain about: the pack is designed for thirty years and warranted for ten. Those are two different commitments and we publish them as two different numbers.

Cycle life
30,000+ cycles at over 80% capacity retention. A lithium pack is typically finished between 500 and 5,000.
Design life
30 years, backed by a 10-year warranty. The pack does not fade while it works or while it sits.
Charge time
5–25 minutes depending on pack and supply. Electrostatic storage accepts charge as fast as the source delivers it.
Operating range
−20°F to 150°F at full output. No cold-weather derating, no heat-related fade.
Maintenance
None. No watering, no equalisation charges, no scheduled replacement, no service interval.
Round-trip efficiency
98%. What you put in is very nearly what you get back out.
Safety
No thermal runaway pathway. Not mitigated by design — absent, because the chemistry that causes it is not there.
Solar integration
Grid-tie and off-grid on the same hardware, compatible with standard inverters.

Services and support

What comes with the hardware.

We are a small company on purpose. The people who answer the phone are the people who design and build the packs, which means you are not explaining your installation to a call centre and waiting for it to be escalated to someone who understands it. That shapes everything below.

Application sizing
Tell us the load, the duty cycle and the environment. We will specify the pack rather than leave you to work it out from a datasheet — how many, what voltage, what capacity, and what it will actually do on the worst day of the year.
Integration support
Grid-tie and off-grid on the same hardware. Compatible with standard inverters and charge controllers, and we will work through the wiring, the BMS interface and the commissioning with your installer.
Technical support
Direct access to the engineers. Phone and email, 8am–6pm ET, Monday to Friday. No ticket queue between you and the people who know the hardware.
Warranty
10 years, on a pack designed for thirty. Register the product after installation and the coverage and serial numbers stay on file, so a claim does not start with you hunting for paperwork.
VAR programme
Reseller and integrator partnerships for installers, system builders and fleet operators — pricing, technical training and support for the people specifying us into their own projects.
Fleet monitoring
Optional Seti AI monitoring for packs in the field, from a single site to a whole fleet — live telemetry, alerting and history, with a free tier that runs on your own hardware.
