Aquion - Battery Reviews

About Aquion

US company Aquion Energy manufactured a non-flammable “salt water battery” (Aqueous Hybrid Ion – AHI) system boasting 100% depth-of-discharge capability among its benefits. 

Other claimed benefits were non-toxicity of the materials used in their salt water battery, extremely low fire risk, and the ability to be fully discharged and left unused for long periods without deterioration.

The Aquion battery had a 5 year warranty, followed by a three year pro rata warranty.

The company collected all sorts of accolades, and then suddenly in March 2017 it filed a voluntary petition under Chapter 11 of the United States Bankruptcy Code as it couldn't raise the funding needed for continued operations. After it emerged from bankruptcy in July the same year with new owners, it reportedly wasn't supporting existing products in any way, and all existing warranties were void. 

As for its production facilities at a former Sony and Volkswagen assembly plant in East Huntingdon, Pennsylvania, those were closed with the intention of shifting production to China. And that was the last we heard about the firm.

If you'd like to learn more about these salt water batteries, we published an in-depth Aquion review back in 2016.

Very few of these batteries would have been installed in Australia - but if you have one, we'd be interested to hear how its been doing.

No other salt water batteries have made it into commercial production since the Aquion as far as we know, and lithium-ion continues to rule the roost in terms of home energy storage. Learn more in our comprehensive guide to home batteries.
