I have a xeno E03 flashlight that runs on 1 AA battery. It can also use a 14500. My question is, can I just run a Lith-ion Energizer AA battery? I don’t want to fry my light. And is it safe to run these lithe ion in any other light that takes an AA? Thanks for any explanation you can provide.
They are safe for any light that uses alkalines, and they last longer and handle extreme temperatures better. Too bad they are so expensive.
Welcome to the cool kids' club, Hunter991!
yes hunter they aren't 3.7 volts they are just 1.5 like a regular alkaline .. they weigh less and are about 4 times as strong and cost lots more ..they are primaries and not rechargable lithium ions they are disposable .. the 14500 is a 3.7 volt ~4.2 volt vattery that is a rechargable lithium ion battery ..they will kill certain drivers that aren't made for the extra voltage
Aloha and welcome to BLF Hunter991!
Yes, you can. It will act like normal alkaline, but with much better result.
But I see you write Li-ion, that Energizer is NOT lithium-ion, and you CANNOT charge that battery. Don't get this mixed up. Lithium primaries will explode if you charge it long enough.
Thanks everyone.. i did mean Lith batteries, sorry about the explanation. I use Alkaline for everything, and never owned a 14500 or 16850 rechargable. Don't even know where to start with that so i thought i would take the next step to Lithium batteries and see if i can get more life out of them.
If more life is what you want, buy some Sanyo Eneloop Ni-MH rechargeable batteries and a decent smart charger. They can be had a for good price in a kit if you shop around. They last longer on a charge than an Alkaline, they will never leak like an Alkaline can, and you can recharge them for pennies over and over again saving money in the long run. I don't use disposable Alkalines for anything anymore - rechargeables only, even in wall clocks, remote controls for the TV, stereo system, etc.
My experience with Ni-MH batteries hasn't been good thou. I have this type of battery in a number of Makita tools (drills mostly) and they drain very quickly if not used. I have had much better luck with Li-on batteries as they seem to keep their charge.
also, do these type of batteries put out the same power as a regular AA Alkaline? Meaning 1.5 volts?
Eneloops have same voltage, plus they are Low Self Discharge. They will supposedly retain 75% of charge over 3-5 years, depending on generation.
That's why bfksc specified "Eneloop" batteries. Search the web for eneloop and other low-self-discharge batteries and you'll see why.
so would it make sense to find a 14500 battery or try the Eneloops? obviously performance may differ but i am not concerned with that really. Again, please realize i have no idea what a 14500 or 18650 battery is.. if its Li-on, Ni-MH or Nicad.
14500 and 18650 are all lion. They have a maximum voltage of 4.2. While Eneloops have a maximum voltage of 1.45 and Alkalines 1.5.
