How are mercury free different from the others?

Mercury free is pretty much all you will find these days. They are different from older batteries in that they use oxygen from the air to produce power, which is why there is a sticker on them covering a small hole to keep them from discharging in storage. You need to wait 1 to 2 minutes after removing the sticker before trying to use them, to give them time to charge up.

Seems to have slightly shorter life, however they are required in some states.

I had heard that mercury batteries actually worked better, lasted longer than the other. Getting rid of the mercury has more to do with batter disposal after use than with the battery service, however. Mercury is a carcinogen so we try not to dispose of it in such a way that doesn't get into the atmosphere through trash burning, or some other way.

The advantage of mercury-free is that it's better for the enironment.However, in the case of Power One, their batteries that have mercurywork great...long lasting; their mercury-free batteries are a disaster,dying in half the time of the ones with mercury. I've given up on PowerOne. Rayovac mercury-free batteries last much longerthan PowerOne's.

They use zinc-air technology now instead of mercury because it is poisonous and bad for the environment.

I can't tell that there is any difference in performance. I assume it's safer if I accidentally lose one and my dog later finds it.

Potassium Iodide 225 mcg 150% of daily. Other ingredients hypo-allergenic plant fiber, vegetable capsule. I see nothing about mercury or bromine. I did some research on this company and they seem to have the purest products on the market for the money. I got these as back-up for radiation poison.

I only use Nordic Naturals for my dog and my kids BECAUSE they are the only company that I have found that regularly monitors and purifies to remove PCBs and heavy metals (i.e. Mercury) from their fish oils. As an environmental toxicologist, this was a mandatory requirement for me.

I looked on the label- it said nothing. Of course, if there were mercury in it, I doubt they'd put it on the label. .. isn't it awful that you even have to wonder??

I believe that this product is all natural. It has no additives, chemicals, or GMO. That would also lead me to believe that it does not contain any leads or metals such as mercury. I hope that this helps.

From their website: "Ocean Blue® Brand of products contain no heavy metals (mercury, arsenic, lead and cadmium) and no toxins (PCB's & dioxins)"

ALL fish contain some levels. I would want to know if this is chelated to remove mercury and other toxins.

No. I had problems with receiving damaged/dented cans that had lost their seal and had to be thrown out. Also, white albacore tuna has the higher mercury content than most fish (because they are higher on the food chain; eating other fish that have mercury in them from environmental pollution. If you eat a lot of tuna, you might want to have yourself tested for mercury.

My guess is that Mercury-free is simply safer. All else being equal, the used batteries that go into the landfill will not contain an environmental contaminant. Free Mercury in the environment is some bad stuff!

the amount of elements which are removed. The cheaper one takes out just chlorine, the more expensive one about 40 trace elements.

Hey there, you may ahve found the answer to your question already but I believe Vega test results come up very clean. Hope this helps. http://www.naturalnews.com/044136_vega_protein_heavy_metals_limits_natural_products.html

Calamari squid have very low levels of mercury. I think it should be safe. If you're interested you can look at this guide to see which fish have the lowest to highest amount of mercury. http://www.nrdc.org/health/effects/mercury/guide.asp

If you look at the label on the front of the bottle, it states "no Mercury"

This is a plant-based product, no shellfish, so I believe it would contain no mercury. It is NOT a fish oil omega 3 supplement. On their website, now foods has an easy-to-read visual of the product label.

Please note that all hearing aid batteries are Zinc Air. What you are probably referring to is batteries with Mercury, which would be the Power One Size 312 hearing aid batteries. Any of the ones listed as Mercury Free would not contain Mercury, and most likely, not be what you are looking for.

All hearing aids, including these are Zinc Air batteries, which uses air from the atmosphere to become part of the battery to produce voltage. Perhaps you are asking about Mercury Free, which are available too, which do not contain mercury, but still are Zinc Air batteries.

Yes, all fish have mercury. The smaller the fish the less mercury. Skipjack light tuna have the less mercury of all fish. So, if you are pregnant, a nursing mother, a very young child or very old unhealthy person one tuna sandwich a week wont hurt you. But beware of albacore tuna it is very high in mercury. If I eat this it is only one can a month and the rest of the month salmon or some other low mercury fish or seafood. Hope this helps.
