Are these mercury free? How long does it last in a single charge?

I am not familiar with the manufacturing constituents of the batteries and could not comment whether any mercury is involved. A single charge lasts at least 12 - 14 hours. I charge the batteries in my hearing aids each night for approximately 8 hours. They perform well until I remove them prior to bed.

No information on mercury. I put them in the charger at bedtime. I have never had them run down, even in an 18 hour day

My batteries last about a year (10 to 12 months) before they don't charge any longer or hold a charge. Each charge will list about 14 to 16 hours and they take about six hours to fully recharge. Don't know if they are mercury free.

Sorry, I can't answer on the mercury free. I thought all batteries contained mercury. I put them in my charger every night and they last the day. I replace them sometime getting close to a year from when I purchase them. I've always used them and like them. Much less expensive than the regular batteries.

I'm thinking they contain mercury. Here is a document I found online. http://www.zendergroup.org/docs/battery_household.pdf

Yes. As far as I know all led bulbs are mercury free. Only flouredcents need mercury to operate.

So sorry for the late reply. I'm honestly not sure if they are pvc & lead free.

All Cree led products are mercury free according to their web site. These bulbs are fantastic. Every light in our house is led and the majority are this 60 watt version

Hi there, I purchased this w/ the hearing aid for my father in law, who is overseas. I'm not sure about the mercury content and I don't have the packaging to confirm.

Misprint; powerone-batteries.com list thier mercury and mercury-free at 1.45v. Other manufacturers list mercury-free batteries at 1.4v. One set of a twelve set package of 1.4v cause my aids to malfunction, I'm staying with the 1.45v batteries for as long as I can.

Honestly, I can't remember for sure whether they were charged prior to using or not. I think they were, but it's been a couple years since we purchased these so I can't say for sure. I do know that they don't ever hold their charge for a very long period of time.

No such thing as a mercury free cfl. You now have to make your own incandescents if you're worried about mercury in your house(and have the local power plant put mercury in the air instead).

Mine work just fine. I'm not sure if the charge value is accurate, as I've never drained it below halfway. They last a long time!

All CFL's have some mercury in the bulbs. There is a warning label on the packages on how to dispose of them.

Tenergy Low Self Discharge rechargeable work great for me. You can shelf them for a year and they only lose something like 20% of the charge.

I don't see a date on them, but I have ordered these batteries 3 or 4 times for at least 10 years. They last as long if not longer than the ones provided by the home security firm. I can't give you a time space, but they work quite well for me.

You can charge any brand as long as it is Nickle Metal Hydride. You can also recharge Alkaline, but that kind should be completely dead to avoid the "memory" effect. Truly, Hank

Yes, my batteries lasted a short time also. I purchased rechargeable ones & the charge has lasted so far 4 months.
