Can anyone tell me approximately how many days one battery lasted? I bought Powerone 312 w/ mercury and my Grams loves them, but wanting to be green.

Hum? Hard to tell. One pair lasted a week another 3 days. Depends on how long they are activated. I usually get 4-5 days but I often don't use my aides except for the evening TV.

Mine last between four and five days depending on how long you have them on.

I have 2 hearing aids - one is wireless as I am deaf in one ear therefore my batteries last 3 1/2 days

7 Days with very heavy use. I wear my hearing aids more than 14 hours a day!

they last pretty long for me. It really depends on the type of item your using these batteries for. But for me they always last at least 5 hours. Theyre pretty reliable for me. They also take like a day to fully recharge for me, i go to sleep & when i wake up their fully charged.

Mine was labeled something else, but most brand name manufacturers contract out batteries and just slap their own sticker on it. What I can tell you the battery I got was a decent one, lasted about 3-4 hrs and worked with all power states and levels both windows and Linux. Just saying your results and mileage may vary, contact a professional if you get mileage or results longer than four hours

The battery is great. I would say it lasts about 2 days even when I am playing games. No problems so far with the memory.

I've been using PowerOne 312 hearing aid batteries for 2 years now and consistantly get 5 or more days uses out of them. I wear my hearing aids about 12 hours a day and they are bluetooth connected to my cell phone.

Get at least the 2.0 amp hour battery. The 2.0 runs me about 1/2 to 3/4 a day of use. I would entertain the thought of the 4.0, but pricing and bulkiness dissuaded me. You can get 2 2.0 batteries for the price of one 4.0 last I checked.

I also agree with Andrew. I bought this battery and simply installed it and it has worked fine ever since (more than 3 months now). I went from about 6 hours per day of life to now about 12 under normal use.

I've had a 550 since October 2008, and I'd say on average the batteries last around 3-4 months. I suggest getting two 4-packs of Sanyo Eneloop AAA batteries and keep one set charged for quick changeovers (they hold a near full charge up to a year). Batteries lasting only 2 weeks does not seem right to me.

the battery works quite well. it lasts at least one to two days if you consistently use it. although its off for a while, you still can turn it on without losing power not being used.

I bought them a couple of months ago. I don't see a date anywhere on them but there is a stamped number of "43" on the battery. All the batteries were fully charged and I did not have any defective ones. I have bought the same batteries before from these people with no regrets.

I sold this to one of the guys I work with some time ago. If I remember correctly a set of 2400mhr rechargeable batteries lasted about 8 hrs. it was about the same w/ the Harbor Freight cheapies.

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.

Since I purchased the Hewlett Packard battery, this is the information straight from their website: "Lower Total Cost of Ownership: One battery has an up to three year cycle lifespan, reducing your overall battery cost since you purchase fewer batteries over the life of the notebook. Flexible Solutions: With up to three years of warranted performance, you can enjoy the entertainment and productivity features of your notebook for longer then with standard solutions." Of course, the actual lifespan of the battery will depend on actual usage and care. It took me three and one half years to need replacement for the first battery; so far, I have had this replacement battery since July 16, 2013; I do not run the Notebook on battery only for long. I make sure to charge it as soon as possible. Hope this helps. Good luck.

they claim 2000 cycles with proper lithium charger, starting it 2xs a week, that should last 20 yrs LOL. If that were true, one would never need another battery if riding that infrequent. My agm only lasts 2 yrs and that is keeping it on a tender 24/7. Every 2 yrs like clock work.

I have never used beltone batteries. however I do know that beltone are mercury free. If this is important to you, you can get Power One mercury-free batteries also available on Amazon. I found Power One to be a good choice for me and I am very satisfied.
