CUSTOMER REVIEWS (Average Customer Rating: 5.0 based on 51 reviews)
| Awesome for a camera flash unit by Nathan Beauchamp (Oak Park, IL USA) 5 Stars November 22, 2009 I primarily use these batteries in my Nikon SB-600 Speedlight Flash. I started using them about a year ago after much frustration with the lifespan of normal alkaline batteries. I am not a professional photographer but it is a pretty serious hobby (addiction my wife would say) of mine, and nothing drives me more crazy than my equipment becoming the limiting factor of what I want to do creatively. Replacing batteries in the flash on what seems like a weekly basis is annoying--running out of juice in my camera flash at the wrong moment is much worse and can even be devastating depending on the context.
Thankfully these excellent lithium batteries from Energizer are truly superior in performance over either normal alkaline or rechargeable batteries. I get 500-700 shots out of a set of these, which makes them economical compared with the seemingly less expensive alternatives.
It is possible to find these batteries in larger packs at big box stores, but they're actually the same price per battery overall. I prefer them shipped free to my door, even if they were slightly more expensive.
These are great batteries for virtually any photography application weather in a point-and-shoot digital or in a flash unit like the SB-600. As other reviewers have mentioned, they are not superior when used in low drain applications like a computer mouse. Stick with normal alkaline or nimh batteries for those uses.
| | It started with a camera by wise1owl 5 Stars November 13, 2009 It all began with a camera. No matter what we tried it seemed to devour batteries. Alkalines, coppertops, bunnies with drums, rechargeables, NiCads, nickle hydrides, nothing was safe.
In desperation, we tried the the high priced (about double that of a typical alkaline) Energizer E2's. They are worth every penny. Nothing less will ever again tough our electronics, digital cameras, remote controls, wireless mice, and even flashlights.
These batteries seem to last forever, particularly with digital cameras. The basic difference between the E2 lithium battery and alkalines, nicads, etc. is that the power is supplied at a steady voltage until the battery is almost completely drained. Then it drops rapidly instead of slowly dropping from the first use. Therefore, your camera has full power until it's time to replace the battery.
Sure, I'm paying twice as much for the battery but it lasts way over twice as long!
| | Excellent Life in Cameras by Lee C. Schwalenberg (Kaukauna, WI) 5 Stars September 22, 2009 #1 for a reason, you will not regret.
Although, I have switched to eneloop rechargeables and will never go back. They are ridiculous price/performance.
| | Exellent low temperature and emergency use battery by Michael A. Duvernois (Minneapolis, MN United States) 5 Stars September 21, 2009 These are expensive for daily use, I'd recommend NiMH rechargeables for that, but they're perfect for low temperature use (car flashlight in Minnesota winter, digital camera use outdoors in the winter) when both alkalines and NiMHs fail to deliver. These would also be, with very gradual storage loss, great for an emergency electronic device. Maybe for GPS or LED flashlight. Do check that your electronics are happy with these batteries installed. I've heard of both digital cameras and GPS units (Garmin GPS60) that did not.
| | Lithium batteries by David L. Wiggs 5 Stars September 12, 2009 I needed a battery that would withstand the rigors of zero degrees (F) for my freezer digital thermometer and this battery has done all I expected.
