It stores your power as heat, not in lithium cells
Renewable or grid electricity charges the system. A patented thermal medium holds the heat, ready to be converted back to power when needed.
- Long-duration power, up to 20 hours
- Designed for off-grid and hybrid applications
- Manufactured in Sri Lanka

The published equivalent system energy and operating duration are based on the complete integrated system under stated test conditions. Final performance depends on site load and engineering assessment.
PROOF, NOT JUST CLAIMS
Tested, not just claimed
According to CeyCell’s supplied product catalogue, independent testing by the University of Moratuwa and reference to IEC 61427-1:2013 support the described technical validation. Certification scope and current compliance should be confirmed before external publication.

This comparison is straight from the catalogue. It puts the two side by side, plainly,
without running lithium down.
| Feature | CeyCell | Lithium-ion |
|---|---|---|
| Energy storage | Stores energy as heat in a patented chemical gel (thermo-chemical). | Stores energy as chemical charge in electrochemical cells. |
| Discharge duration | Long duration — up to 20 hours of power continuously. | Short duration — typically 1 to 4 hours. |
| Safety | Non-flammable, non-explosive, and heat stable. | Flammable, with a risk of thermal runaway and fire. |
| Lifespan | Extremely long cycle life, with minimal degradation. | Limited cycle life; performance degrades over time. |
| Environmental impact | Eco-friendly materials, non-toxic, and fully recyclable. | Uses critical minerals, chemical electrolytes, and toxic materials. |
| Maintenance | Low maintenance; robust and durable design. | Requires active management and temperature control. |
| Operating conditions | Performs across a wide temperature range with high reliability. | Performance is affected by high and low temperatures. |
| Total cost of ownership | Lower — long life, safety, and low maintenance. | Higher — replacement, management, and safety systems. |

The things people ask first
Is it a lithium battery?
No. CeyCell is presented as thermo-chemical energy storage rather than a conventional lithium-ion cell pack.
Is it safe?
Its published design includes a sealed enclosure, passive thermal management and other listed safety features. Appropriate installation and site assessment are still necessary.
How is it tested?
The provided catalogue references University of Moratuwa testing and IEC 61427-1:2013. The scope of each test should be checked against the relevant report.
How long does it run?
Up to 20 hours is the published maximum claim under specified conditions. Actual duration depends on the load and system selected.
What does it cost?
Price is quoted according to system size, installation conditions and the site requirements.
