Product Description

Aeternus 12V Power Pack

The Aeternus 12V Power Pack is a new concept of battery with extremely long shelf life and superior safety yet providing high currents capable of operating various household appliances such as lamps, portable fridge, charging cell phones or walkie-talkies, via inverter. It can also be used for emergency starting a car, which uses the identical DC 12V system.


Nominal Voltage: DC 14.4V

Capacity: 40Ah or 540Wh (under 1.2A continuous discharge)

Max. Current: 5A

Operating Temp: -25 ~ 60 degrees celsius

Dimensions: 170mm x 180mm x 78mm

Weight: 2.5kg

Exclusively by EMW Energy

- Aeternus 12V Power Pack is the WORLD'S FIRST zinc-air battery for civilian use and we are the SECOND IN THE WORLD to have developed 3rd generation zinc-air battery (zinc-air battery for well known hearing aids are considered second generation zinc-air battery, only capable of small output)

- COMPLETELY STAND-ALONE TECHNOLOGY with over 60 patents worldwide

- IN-HOUSE MANUFACTURING PROCESS from mixing raw material all the way to final product means easily customizable battery within reduced time

- ELIMINATED PLATINUM CATALYST thanks to MEA, an exclusive technology by EMW energy reducing cost

Advantages of Zinc-Air Battery

1. Does not contain anode within the battery pack

- HIGH ENERGY DENSITY in both terms of weight and volume

- STABLE VOLTAGE DURING DISCHARGE: unlike conventional batteries which undergo proportional voltage drop as discharge continues, eventually causing devices to shut off before the battery is fully consumed

- EXTREMELY LONG SHELF LIFE: Just by simply blocking air flow into the battery stops the chemical reaction needed for the battery to discharge

- COMPLETELY SAFE WHEN DAMAGED: Unlike lithium batteries, zinc-air battery does not ignite or explode even under breakage because zinc-air battery is intended to contact with air to produce electricity

2. Aqueous Electrolyte

- STABLE VOLTAGE AT ALL USE: Lithium batteries require multiple protection circuits which restrict usage under low/high temperature, short-circuit, over-discharge, etc. because even small voltage deviation may cause irrevocable situations

- UNRESTRICTED AIR FREIGHT: Shipment of lithium batteries have recently been banned on all passenger aircrafts (effective April 2016)

- NO HAZARDOUS METALS such as lead, mercury, etc.

- ENVIRONMENTALLY FRIENDLY enough to be disposed as domestic general waste

- WIDE OPERATIONAL TEMPERATURE ranging from -25 to 60 degrees celsius, capable of storage in all range and humidity without great loss of performance

3. Plentiful Resource

- GREAT BANG-FOR-THE-BUCK: Zinc is a plentiful natural resource easily found anywhere on the crust of the Earth meanwhile lithium is only found in certain regions around the world and is extremely hard to extract (Zinc is 1/5 the price of lithium while holding TWICE the energy)

About EMW Energy

EMW Energy has been focusing on development and manufacturing of zinc-air battery since its erection in 2006 and has grown to become one of the TOP 3 manufacturers of next generation battery beginning with the achievement of developing zinc-air battery for electric vehicle capable of 300km range in 2010. In 2015, its first mass production zinc-air battery, the AETERNUS successed in penetrating disaster prevention/relief market as well as stepping its first foot in the defense industry. Its future vision includes secondary(rechargeable) zinc-air batteries for various uses, such as electric vehicle & charging stations, military applications ranging from drones to generator replacement, energy storage system, etc.
