      Don't bother - stick to Alkalines

      I really can't say enough about how bad these batteries are. Please note that I'm a mechanical engineer by schooling and have been somewhat of a "battery aficionado" for 30 years or so with my charging and discharging experience of batteries for my hobbies (radio control, cars, cameras, electronics, etc). Nimh batteries are inherently only 1.2 volts. When manufacturers make their devices, these devices are "expecting" 1.5 volts such as what is provided by Alkaline batteries. So your "low battery" warning, if your device has one, will trigger much much sooner since your battery is starting "fresh" at 1.2 volts vs. 1.5 volts. Further, the 15 minute Energizer charger charges at an astronomical 7 Amps! This gets the batteries crazy hot. Heat is not good for batteries and they will die (i.e. - not be able to recharge anymore) much sooner = DEFINITELY NOT the "recharge 100 times" claim. Of course, if you use a "slow" charger, then yes, the batteries should last much longer. Charge over 100 times? I doubt it. So why shouldn't you buy these batteries? 1) Add the more expensive cost of these batteries 2) The cost to charge them at 7 amps (which I can imagine is a lot since refrigerators draw 15 amps!) 3) The fact that the 15 minute chargers kill them more quickly, it should really push you to go back to Alkalines. 4) They don't work as well as Alkalines in colder weather (i.e. - try using the flash when it's 15 degrees outside and you'll notice that the batteries, although freshly charged, won't work so well. Pop new Alkalines in there and voila! You got flash back). So in a nutshell, I'm going back to Alkalines. Or even better, go with Lithium Energizers which will last that much longer! Both don't contain any mercury and you can safely throw them in the trash.

      I purchased a charger (it came with 4 AA batteries) and a pack of 4 AAA batteries. I originally purchased these batteries because I bought a Turtle Beach 5.1 surround sound headset (to play or watch movies late at night without waking others up). I had read reviews on the headset that it consumed batteries like a kid consumes candy. I got home and prepared for the test. I was extremely happy with the results. The headset lasts for a good week and a half (3 hours or less playing non-stop per night) which is ok, considering it produces surround sound wirelessly. Though I initially didn't really plan to use the AA that came packaged, I tried them on my Xbox wireless controllers. To my surprise, they last about 1.5 times longer than the licensed battery pack from xbox. In the controllers, I can easily play for 2 weeks straight without needing a recharge. Now, I bought a separate charger for my wife to use on her mp3 player (single battery AAA) and that can go on for a whole month. I am now going to buy some more batteries for a remote control helicopter toy and they will stay in that remote permanently. Though many people complain about the price, I don't, because I am more than getting the value of the batteries. I think they are priced just right. Think about it, regular batteries cost anywhere from 4-5 dollars with tax. Having these batteries is equivalent to having purchased at least 10-15 packs of batteries per year (depending on how you are consuming their power). TIP: I agree with another reviewer, keep an extra set fully charged so that you can just swap batteries on the fly. The charge time on these is 9 hours for a full charge (but can be removed before the 9 hours if you need them and they would last a fair amount). Though many may frown at this wait time, we have to remember that those 9 hours are saving you money. Charge them while you sleep, and keep the extra set charged. They don't loose their charge if not being used. We can't expect society to be giving us instantaneous results without hindering value.

      Surprised at how long they last

      I have used a 'heavy duty industrial, low-impedance' line of rechargeable batteries & a 'pro' charger for years. The charger is about 3x the cost of consumer models & usually found through battery distributors. I was skeptical about purchasing these batteries for household use after being used to industrial battery performance. If you are not getting satisfactory results from these batteries it mite be the charger. There are differences in the charging units and even though the charger says that the battery is full, it can only charge the cell to its own charging capacity. If you have a 2700 mah battery, your charger has to be able to charge it to that capacity, if isnt able to - the battery performance will suffer. It is also important to 'condition' the batteries rather than continuously rapid charging them. Digital cameras are notoriously high drain because they also power the flash as well as the camera. I condition these batteries in the above mentioned charger and get great results from them in a point and shoot Canon digital camera. They dont drain over time (weeks) and offer fast camera flash recycle time.

      Best rechargable batteries you can get locally

      These particular energizer rechargeable batteries I purchased are the higher capacity 2300mah batteries. They are the next generation of NiMH batteries with low self discharge. It used to be that rechargeable batteries would not last long in a low power device such as a remote, but excelled at high discharge applications like camera flash units, and flashlights if used directly after charging. These give you the best of both worlds; Charge retention along with low self discharge to last long if not used or used lightly, but also have the ability to power devices that pull alot out of them. This is a great all around battery that I rate just slightly lower than the Panasonic eneloop pros that are much more expensive and harder to find, but I'll still give them 5 stars due to pricing and availability.

      I have had a AAA and AA 4-pack sets for about a year and I am going back to get some more (only for extra devices and to have spares). All the good things are true as with the idea of recharging batteries. less waste, you don't need a stockpile of batteries sitting around the house. these last longer than any set I've tried before and I haven't noticed much power dropping until they are just about to need a recharge. They work great in the devices i have them for (Currently 2 TV remotes, 1 wireless gaming headset and my 4 Wii controllers). I don;t know if i would use them for high demand products like battery operated mixers and shavers and stuff where you need alot of power but passive devices like what ive used them for they are great and last almost as long as single use (or at least not a noticeable difference). My only advice is to have at least one or two extra pairs than the number of devices you are using because its nice to have a charged set ready to go when you need to replace. that way you just replace the dead with the charged and put the dead ones back on the charger so they are ready for the next swap

      While it may be a bit early to give these batteries a high score, I can say that they last a long time (before they seem to die out). I got these on sale, and for what I am using the batteries for, it works out to be a great bargain (mainly used to power my computer mouse, speaker, WII Controllers, and Gameboy). When they no longer power the devices, I swap them with freshly charged batteries and begin their re-charge process. Admittedly, they are not the best for flashlights or other items I might take with me out of the house (when I don't have the spare batteries readily available). But, when freshly charged, they do power the flashlights as well as most other batteries. Finally, I already had a charger, so this high review is mainly because of the low price I paid for them.

      Economical and responsible battery use

      These rechargeable batteries are easy to use and last well once charged. The value is probably the greatest combination of thrift and responsible debris management. You get a handy, always on hand, source of batteries that save you 500 or more regular batteries AND you do not have to dispose of 500 or more dead batteries. It is so obvious that Energizer NH rechargeable AA and AAA batteries serve for LED flashlights, candles, cameras, compact recorders, thermostats, with cost savings, disposal issues and just having them on hand as needed that anyone who does the math should agree. A small up front premium and hundreds of dollars saved over the months of usage.

      Great battery WIHT the right charger

      This batteries are good, but you need to give them the time to charge well (8 to 13 hours) I have a 4 hours fast charger and the original from Energizer (~8 hours) and you can notes the difference with the full charge. I use them with my canon and sigma flashes, and I love to take pictures, day and night with flash (you can see a nice touch in day light) and I have to say that 4 hour quick charge is just a QUICK CHARGE, do not last long... Do not charge 100%. and after using all the energy from the battery, takes up to 13 hours to fully charge. Bottom line, I recommend this batteries to a friend, but, only if he/you get the right charger for it. Hey, full charge... priceless.
