Review: Work great, especially in applications where NiMH batteries are problematic - I've been using rechargeable batteries for decades, going all the way back to the days of the dumb charger and NiCd cells. I simply refuse to purchase throwaway batteries not only because of the environmental benefit of rechargeable cells, I have had my fair share of things ruined by alkaleak cells. I have several very finicky devices, mainly security devices and Friedrich wireless thermostats that simply do not play nice with my trusted Eneloop batteries. I purchased two, eight packs of these XTAR LiOn AA cells to see how they would behave in my troublesome devices. So far, they work perfectly. I have conducted several detailed load tests on these cells, ranging from a 0.2A to a 0.95A sustained, constant current discharge test to measure capacity. While none of the cells make it to 100% of the advertised capacity at a discharge current of 0.95A, they all performed very respectfully under the current load, delivering a sustained output of 1.5V for over 100 (0.95A) and 400 (0.2A) minutes respectfully. I have not been able to duplicate the reports that the cells get hot when in use, but they do get warm under a sustained heavy draw. I measured a battery temperature of 38C during the 0.95A test. Keep in mind that the cell undergoing the test was not inside an enclosed flashlight or similar enclosed space, so the temperature that the cell could reach in an enclosed environment may be significantly higher than when testing on the CBA. As to longevity, and whether these cells will reach the advertised number of cycles, that's hard to say given the length of time that I have had the cells in operation. My verdict, based on my experience and testing is that these cells appear to be of high quality, and they deliver as advertised. Putting the batteries to the torture test utilizing a West Mountain Radio Computerized Battery Analyzer, all of the cells exhibit a relatively flat discharge curve, with the loaded voltage staying between 1.5 and 1.45V right up to the point that they switch down to 1.2V before the cell is completely flat. The cell tested at 0.95A gave NO indication of stepping down to 1.2V, it simply shut off. If you are relying on a low battery signal to be displayed on some device that draws a heavy load, I suspect you will never see the warning before the cell shuts down. This is repeatable, in testing five cells at 0.95A not one cell gave any indication of dropping the output voltage to 1.2V before shutting down. However, at the lower current of 0.2A, the cell does drop its output for a significant amount of time to 1.2V which should be more than sufficient to trigger a low battery indication on most devices. All of the cells exhibit significant radio frequency interference when used in a portable radio rending the audio unintelligent. When used in my alarm sensors, or my Friedrich wireless thermostats they perform flawlessly. Will I replace all my trusted Eneloop cells with these batteries, in a word, no. Do they have a place in the modern electronic world, absolutely. I intend to take one cell and put it through a torture test of continuously charging and discharging the cell to see if I can get anywhere near the advertised cycle capacity and will update this review then.
Review: Yup! I'm excited about these batteries. - I'm excited by not having to buy single use lithium batteries again. These have higher power per charge than even the most expensive ones. I got tired of spending on that. Key: these batteries have a green indicator light when going dead. I use them for work and will no longer have to be surprised by them going dead. I bought 12 batteries. For my usage, that seems ro be enough power for 56,000 hours. If I were to get 4000 hours out of these I would be completely thrilled.
