You could try using a LiFePo4 battery instead which has a slightly lower voltage of 3.2 instead of 3.7 to prolong possibly the life of the light. Considering most decent keychain lights are around $10, if it burns out after a year you could just buy a new one.
Good for a backup but Not my main Flashlight, I might slap in a 1440 in an emergency like Zombies, vampires, etc. but voiding the Warranty is too risky. good review.
No one mentions that the i3t's low mode goes from 5 lumens to over 50 lumens for over 2 hours with a 10440. That makes it a great work light for me with a bonus turbo charged high mode. Along with my i3t I carry a spare tiny 10440 in my pocket.
@@southerndualsport3827 Did a search and the standard Energizer AAA is 1150 mAh, so it's 3 times the energy storage compared to my 3.7 volt 10440. The Energize AA is 2779 mAh. The i5, in the end may be the best bet. Or get the i5r with the USB-C charging battery that is 2.4 volt and 1420 mAh and can use standard AA batteries
@@HopsAndLead Yes, I am using this in my break down kit on my adventure bike, I'll usually have plenty of other sources, but this is my bare bones last resort I want to always work. I'll order the Energizer ultimate lithium, they run at a slightly higher voltage and have a big capacity and very long shelf life so thanks for the help!
@@southerndualsport3827 That'll definitely work. Pretty sure running a 10440 from full charge to dead will make short work of the i3t lol. Glad to help!
I haven't used my i3e longer than 2 minutes and it hasn't taken a dive yet. Recently switched from my old FDE Olight Elite i3e to the orange one. We'll see if the new ones are any different than the 2+ year old ones. I3t's, I don't really carry, I stick with the warrior mini or Brinyte PT28
@@HopsAndLead understandable. I might just run my 3e and 3t to the ground. I do carry a baton 2 i just wanted to test out the 3s because of how small they are
