A Lithium Battery may cost 5 times more than an Alkaline Battery, but it will last for about 8 to 10 times longer in operation, with a similar shelf life when not in use. 1 longest-lasting AA Battery Superior performance in extreme temperatures from -40 to 140 degrees Fahrenheit 33 lighter than alkaline batteries makes. Their cost per hour of operation is actually less than that of equivalent alkaline batteries. Airlines warn against bringing lithium battery cargo unless special safety packaging and permits have been arranged.Īt room temperature and under normal circumstances lithium batteries are safe. Alkaline batteries are less likely to present a fire danger. Microphones and Smoke Alarms use alkaline, not lithium batteries.

There are some cases in which alkaline batteries are preferable. Massimo 300W 12V Portable Lithium Battery Power Station Reliable Lithium-Ion Powered Battery Power up to 9 Devices at the Same Time.
Photographers, radio communications experts, and those who depend on medical devices prefer lithium batteries.

Furthermore, Lithium Batteries hold on to their full voltage to almost the end of their charge life, while alkaline batteries decrease their voltage output throughout their performance.
In a case study on Energizer AA batteries, using Energizer Ultimate Lithium and Energizer Max Alkaline, the lithium batteries were shown to outlast the alkaline batteries for 8 and even 10 cycles longer. So Eneloops get my renewed respect for a 3xAA solution as well as Li-Ion for everything else.Lithium batteries are more expensive than their alkaline equivalents, but perform for a much longer lifespan. To demonstrate what all this fuss is about watch this video and see what happens. Spare Batteries And The Risk Of Short Circuit & Fire. Lithium metal batteries are limited to 2 grams of lithium per battery and must go in carry-on luggage only if they are loose and spare. Or some trip abroad where you don't want to carry around junk. Some extra long lasting lithium batteries are made in AA and AAA versions. The only advantage of L91s is where you are going into a situation where you don't want to carry back the empty cells, for example hiking a steep mountain where you are already overloaded and every once counts and you don't want to drag down a bag of NiMh to be recharged back home. Energizer Ultimate Lithium AA Batteries are ideal for high powered devices like digital cameras, portable MP3 players and game controllers. 2,548 7 offers from 25.95 Energizer AA Batteries and AAA Batteries, 24 Max Double A Batteries and 24 Max Triple A Batteries Combo Pack, 48 Count 48,434 Amazon's Choice in AAA Batteries 9 offers from 26. I think all in all, they are superior in providing a flat performance curve versus anything else and almost as good as other cells in terms of self-discharge. Energizer Ultimate Lithium AA 12 Battery Super Pack. I like Li-Ion technology more and more, after 10 years of using 18650s. Perhaps Malkoff M61LLL and a 4xAA configuration would be idea, perhaps two "9P" bodies put together. This differs significantly from charging lithium batteries and their constant current stage and constant voltage stage. Occasionally, there are equalization and maintenance stages for lead acid batteries as well. They are only good for a battery vampire. When charging a lead acid battery, the three main stages are bulk, absorption, and float. Even though most devices and gadgets now use built-in batteries, the best AA batteries are here to stay. I thought that given that alkaline begins at 1.55V, 1.65V is still semi-used but apparently it's pretty close to zero. Allmax AA Maximum Power Alkaline Batteries. Nowhere near 8-10 hours that you are supposed to get.Ĭonclusion: Resting voltage on a L91 means almost zero about how much capacity is left.
Swapping the bad cell, I would return to decent performance - for a relatively short while. Upon checking the cells, I discovered that typically one of the cells would go to 0.48V while the others maintained 1.60V fairly well. The next stop is, I tried Malkoff M61LL running on 3 of these L91s and got it to run for an hour to 1.5 hours, with decent lumens the first 30-45 minutes and then going into the moon mode. I tried a few and they either don't power on at all or display a message "Low Battery" and the device shuts down. It takes 3xAA types or one factory 2000 mAh cell. None of my 100+ cells at 1.65V could power on the Garmin Montana GPS.
