Tenergy Premium PRO Rechargeable AAA Batteries, High Capacity 1100mAh NiMH AAA Battery, 8 Pack Rechargeable Batteries

Real money saver ! These are Tenergy's premium rechargeables and hold more and last longer after charging.

The media could not be loaded. I don't see myself ever going back to anything else. I did a lot of research and these kept coming up on top and found them to be the best for our needs. We use these for everything, flashlights, remotes, string lights, electric toothbrushes, candles. After 1 year we have had no real issues. As time went on, I bought an additional charger. They last 2-3 days in led holiday string lights (we run 24/7 on those), 5-7 days in candles, they last months in electric toothbrushes/remotes and weeks in my led work flashlight. We bought more and more batteries so we can have a perpetual supply ready to change out during holiday and simply got used to spending a few minutes every few days changing and recharging. At about $2 per AA batteries, less for AAA we have saved so much over time because we have now charged some over 60 times. Less guilt now with all those Alkalines we threw away in the past. So the little things, batteries are a little bigger than regular size, so some things are a tight fit. They do last a little less than disposable batteries. It takes 6 hours to recharge them, so we solved the problems by slowly buying around 80 AA and 60 AAA so we never run out. A few lost the black coating around the + terminal, but hasn't effected operation at all. ZERO have failed. If they live up to the 1100 recharges, they will have saved us thousands of dollars in disposables.

These are not good for 1200 charge cycles. not even close. I estimate I got an average of about 100 charge cycles over 18 months before they stopped taking a charge (flashing light on charger). It could just be that they are not adequate for the high power demand of LED head lamps. They Definitely saved me money over non-rechargeable, but they need to get real about the exaggerated charge cycle claims.

I've been using rechargeable batteries for 10+ years and have tried half a dozen different manufacturers. None can match the reliability and endurance of Tenergy. I have a couple of dozen that have been in my rotation for 8+ years and still going strong. This is a new product (for me) from Tenergy, but I'm sure it will perform like all my others. HIGHLY recommend!

These batteries allow me to extend telephone operation from about 3-4 hours to 6-8 hours. These Tenergy rechargeable batteries have 1100 mAH capacity while the batteries that came with my cordless phone & answering machine have only 550 mAH capacity.While the battery backup time for the handsets with original batteries that accompanied my Panasonic KX-TGM430 cordless phone system will last for many hours (13 hrs in continuous use, 9 days in standby), the backup run time for the base unit with answering machine is much, much less (3 hours in continuous use, 4 hours in standby).What does this mean? Run time for battery backup of the "system" essentially depends on the weak link--how long the base unit remains operational. Because the base unit must be working for the handsets to communicate with it in order to make or receive a call, functioning telephone service quits as soon as the base unit loses battery backup (3-4 hours), even though the handsets have many hours or days of battery life left.Important: When choosing which Ni-MH batteries to use (a lot of choices), you must consider more than mAH capacity. How often the batteries will require discharge is another important issue. For example, a cordless phone that is plugged into the wall where from which it routinely receives its power will go through few recharge cycles over time and does not require daily recharging as a solar powered landscape light does. So, if a battery has higher capacity but fewer recharges available, it's a better choice for powering things that need battery backup on rare occasions (like and indoor cordless phone) than for powering items that must be recharged daily.Also, be sure to observe the operating temperature range for the battery. A device that is powered or routinely used outdoors will require batteries that are rated for the extremes of hot and cold weather for the area and seasonal conditions at hand. A device used in an air conditioned and heated home will have no such restriction.

Although frequent recharging is necessary, purchasing batteries remains a cost-effective practice..

They look nice. They're rechargable, but they don't last long at all. I have them in tv remote, roku remote, and stereo remote have to recharge them every couple of weeks.
