The H2OnlyBattery is the first and only battery / generator that is activated by water or other liquid

A completely new technology for up to date data.

“OPEN TYPE” systems, that give the possibility to each user, to pause and restart of energy whenever he needs.

The H2Only Battery is a monumental breakthrough in the Energy sector. Starting from the principles of the ancient Baghdad Battery, we have advanced it in all aspects: power output, customizable size,duration, safety, also added the innovation of PAUSE and RESTART of the production of the Energy.

  • Instant supply of energy anywhere, anytime, again and again
  • Activation with water or any liquid
  • Lifespan of decades depending on usage
  • No expiration, no leaks, no disintegration even if unused, and not subject to ageing
  • Does not contain or emit toxics or chemicals
  • Renewable, recyclable, sustainable and safe for the environment and the humans
  • CE certification for safety
  • Greek Patent, internationally registered (Valid until 2032)


To activate the H2OnlyBattery

One has to instantly dip it in a glass of water, in a stream, in a river, in the sea, in any liquid medium, or simply pour water on it. In case of emergency, urine will also work.

The Battery will then instantly begin producing electricity which will last for as long as the sponge is moist; this could last for several days depending on climate.

When a drop in the output is observed, a simple re-wetting will restart the process. If the Battery is allowed to perform a full cycle (ie. operating time=drying time), it will operate at its maximum power when restarted.

If you want to store it, should be intensively dried your battery. Store in a dry place, and as long as it remains dry, will not deteriorate.
