FREQUENTLY ASKED QUESTIONS
How does it work?
Dip the HydraCell for approx. 10-15 seconds in any water, this causes a chemical reaction between magnesium and oxygen, inducing an ionic exchange releasing electrons (power), which are then collected by the carbon cathode collector and converted into power.
How long can I store it?
From new there is a 25+ year shelf life if stored clean and dry. The replaceable HydraCell can be stored prior to first use for 25+ years and is activated instantly to full capacity simply by dipping in water. Once activated the cell will operate continuously under load, requiring only periodic re-hydration.
How long does one cell last?
One cell will give you roughly 200+ hours of power. That means 200+ hours of turned on light time.
How many times can I dip it?
As many times as you like, although we do recommend you add 5% salt solution (tablespoon of salt in a glass of water, ocean) after the 5th dip onwards. This is required if the power output is down and to maintain same brightness. The HydraCell comes preloaded with salt for easy use, but after multiple dips in fresh water the cell may need to be reintroduced to salt or an electrolyte solution.
When does the power output stop?
From new until the magnesium rod is needle thin there’s a linear power output (same power until the rod has been consumed). The cell is exhausted when the anode is fully depleted.
How do I recharge the battery?
It’s not a battery its an oxygen fuel cell (a low power generator) and to restart the cell you simply need to re-dip it again for 10 seconds. (Until the consumable anode is depleted)
What if I keep it submerged, will I have abundant power?
No, as oxygen is the fuel if it is submerged eventually the chemical reaction will stop (needs to breathe) also as there’s an absorbent membrane holding the liquid it could swell and cause damage to the cell.
Does it have to be water?
No, you can use almost any liquid within reason (not oil).
Can I put it into my other products?
No, because the cell is only 1/3 of the puzzle. More importantly is the electronics board which regulates and controls the output of the cell and finally our products vent as oxygen is needed.
What power output does it have?
HydraCell has a number of fuel cell configurations starting from 1.5 volts with 2 amps with others exceeding this output dependant on appication.
How do I know if my Hydra-Cell needs to be replaced?
Generally a HydraCell will need to be replaced after more than 300 hours of runtime. If you are experiencing low light or constantly having to dip the Energy Cell, it may need to be replaced. The replaceable HydraCell can be stored prior to first use for 25+ years and is activated instantly to full capacity simply by dipping in water. Once activated the cell will operate continuously under load, requiring only periodic re-hydration. In certain conditions the HydraCell will dry out prematurely, especially in warm environments and may need to be dipped in water more frequently.
Does the Hydra-Cell have to be dipped into salt water?
The answer is ultimately yes. However, the first 4-5 dips can be in fresh water as the fuel cell is preloaded with salt. After this time, you need to switch to salt water. This can be ocean water or table salt in tap water (5% solution). This is approximately 5gms of salt in 95mls of water. Or roughly 50gms of salt and 950mls of water will make 1L of 5% solution.
Is there any harmful chemical residue?
No, the residue from the Hydra-Cell is entirely biodegradable.
Can you buy spare cells?
Yes, you can buy spare cells. They will be available to consumers in both single and double blister packs.
Do you use ethical labor practices?
Hydra-Light International is committed to conducting business in a fair and ethical manner and does not deal with any companies or manufacturers employing child labor, specifically anyone under the age of sixteen. Our products are produced by manufacturers that conduct themselves in a wholly ethical manner and Hydra-Light International requires that these companies understand and fully comply with International Labor Standards and International Labor Laws.
