Unless commonality of the form factor, or other practical reasons like that are the top priority, lithium offers the best balance between performance and storage readiness.ĪAA cells, used in triplicate, are common because they can supply the voltage in the operating range of most LEDs. They're not nicknamed "alkaleaks" for nothing. I wouldn't consider regular alkaline cells for anything that won't see regular usage or maintenance. Quality NiMH cells like Eneloops have excellent self-discharge characteristics, and are less temperature sensitive, but only provide average performance. In terms of battery chemistry, lithium has the highest energy density, good self-discharge rates, and will provide the highest performance. The last AAA flashlight I tried leaked after a few months of light usage years ago.Īny thoughts/suggestions/recommendations welcome - thank you! Questions: Anyone recommend good AAA batteries for LED flashlights? I'd like to go rechargeable AAA as I already have a charger. Our old 2016 Anker flashlights still work really well today (original battery) but getting rid of micro-usb. Thought about this but I'm done with micro-USB cables. Also, the manual for this flashlight states I need to take out the 18650 battery when not in use?!. The flashlight also takes 18650 batteries but after spending considerable time on Amazon looking at these, I couldn't find a reputable company that I'd trust. The GearLight above at least takes AAA and I know I can get rechargeable AAAs and or Made in USA AAAs so I figured ok, I'll just do that. What surprised me was, I was really hoping to find a rechargeable flashlight with USB C and I really didn't find anything I liked. Had some MagLite LED flashlights but they kept losing power as I shook the flashlight so I gave those away. Finally upgraded the flashlights in my house after the ones we had got a wee bit old.ĭecided on to replace all the ones we had (failing rechargeable lantern, 2 rechargeable Anker flashlights from 2016, etc).
