Geyser Batteries Oy
Powerful, Durable & Safe Energy
We combine the energy storage capabilities of the batteries with durability and power of the
supercapacitors in a single electrochemical system. This means our batteries are both powerful
and have good energy density. They last way longer than traditional batteries minimizing
environmental impact of the transition to an electrified world.
Our batteries can be charged/discharged for more cycles than any other technology and are
recharged almost instantly every time. The bipolar design of our batteries gives the largest
possible current cross section, across the entire device, resulting in very high currents with low
heat generation and easy cooling.
Our batteries are produced using widely available materials and water-based electrolytes. This
enables energy efficient production, and means that our devices do not contain any toxic or
