Rated 1 out of 5 by from Battery do not waste your money or time. what is the trade off here? batteries that need constant charging or the "green" feeling. I was very disappointed with the battery. Does not hold a charge for more than a day before needing to be re-charged. I try to be as 'green' as the next person, but if I am going to be re-charging batteries all the time for a days use, I will get the standard battery that has a longer life. This was a real waste of my money, the batteries and charger are headed for the re-cycle bin when I finish this review. I have tried other brands and have gotten the same results. Rechargeable batteries, at the moment are not worth the effort.

Rated 1 out of 5 by from Not the best battery for this type of us I am an avid hiker/backpacker and pro wildlife photographer. These are not the best choice for GPS use. They tricle discharge over a farly short period of time. I have tested AA batteries. I currently fire up to 9 Nikon flashes using Sanyo ENELOOP rechargeable AA batteries. Once charged they hold their charge longer than any other rechargeable battery. I've used the eneloops on three continents so far without one issues. Exactly what you want and need in a GPS! Alaways carry a spare pair anyway if you depend on a GPS heavily. REI does not sell them unfortunately.

Rated 3 out of 5 by from Unreliable I bought these for my digital camera and frs radios. They charge quicly and hold a charge for a long time - at first. But after a few months they start to die quickly, in use or not. Mine just recently gave out after a couple hundred pictures, when they used to last over a thousand, and when I replaced them, the replacements were dead in my pack. I'd say if you use these, toss them after a year at the most, and replace them. The charger works great, and is quick. That is the big advantage. But the batteries have a limited lifespan. Don't get your hopes up.

Rated 1 out of 5 by from Use with caution These batteries are fine for around the house (TV remotes, PlayStation guitars, none essential items) but don't use them for backpacking or in items that you need to work i.e flashlights, GPS etc. They won't hold there charge. I have to charge my extra batteries every few weeks so that they will have some juice when its time to change out dead batteries. They also weaken quicker than a standard battery. I had planned to use the rechargeable as a replacement to buying batteries all the time, but they fall short of regular battery's so not only are you going to buy rechargeable (twice the expense of alkaline plus the charger) but you will have to keep regular batteries on hand for dependability anyway. In my opinion not worth the money/

Rated 2 out of 5 by from Agreed I agree with these other reviews. 2,500mAh of rechargeable capacity sure sounds awesome, so I bought a bunch of these along with a top-of-the-line smart charger for use in a GPS, a SteriPen, a digital camera, and assorted other gadgets. The first few outings were awesome -- I was able to keep my GPS powered on all day long for upwards of a week carrying a set of eight. But that was two years ago. Now? I'm lucky if they hold a decent charge for 2-3 days. And in something high-drain like the SteriPen, they're really, really hit-and-miss. Sure, I always bring tablets as a back-up, but having to use them on every outing is getting old -- sometimes, even just a day or two after taking them out of the charger, a set of these can't get through a full SteriPen cycle. My smart charger tells me how much power it fed into each battery, and only a few from my original fleet still get close to their 2,500mAh rating. Mine are all 4-5 years old now, so maybe they are beyond their usable cycle and need to be replaced. Maybe they weren't stored properly, or perhaps the technology has been improved since then. But all things considered, these haven't saved me many disposables -- I take Lithiums now to power the SteriPien -- and I'm very, very hesitant to invest in more. Nice try Energizer, but it appears that NiMH technology is only really beneficial to those who constantly go through a massive number of batteries. For us more casual users, these appear to only last a season or two.
