The AAA's followed in the early 2000's, and I've been using these ever since then. in fact, I have AA devices still serving infrequent use with some of the earliest Lithium Iron cells Energizer made, 1989-1990 vintage, still providing max voltage and service power. For the first group the just-in-case, time-of-need devices relax for a decade and more, all the while ready to do their job - proven! For the second group, low discharge devices like the Fenix E01 AAA light lasts for thousands of 30 second uses, an at-full-performance service life of many years before the cell is depleted - proven! For the third group, high discharge devices, the service and cycle life of a 1200mAH AAA or 2500 mAH NiMH gives better service than the best Alkaline and saves the cost of hundreds of primary cells - proven (with good quality NiMH cells)! No more ruined devices, no more disappointments at time-of-need, much better use of funds.Įnergizer Ultimate has been the brand of choice from its early development. the last category gets 2nd generation (low self-discharge) NiMH cells. The first two categories get Lithium Iron cells, either L92 AAA's or L91 AA's. I decided long ago to divide my devices into to categories - just-in-case, time-of-need devices, low drain /regular use devices, and high drain regular use devices. Hard lesson to learn, and something we should take to heart, yet sometimes the lesson is repeated over the years.
