  • Rechargeable Lithium AAA batteries. Any good?

    Has anyone tried these batteries?

    No...but the advertised capacity seems pretty low.

      I use Eneloop AAA's whose capacity is 800 mAh.
      These Lithiums only advertise 400mAh. Does seem pretty low.

      These batteries advertise 1100 mAh.

        I've been using these in my SPOT for several years and have no complaints...

          You should double check all this because I might be an idiot and completely wrong about all of it. But if I'm not. . .

          These are lithium-ion batteries, like in laptops and cellphones. They are not primary lithium cells, ie "Lithium" batteries. I think they used to be called camera batteries and are usually the most expensive type, and not rechargeable. A Lithium AAA capacity should be more like 1200 mAh. Lithium batteries are the ones recommended as best for cold weather use.
          Li-ion batteries I believe are comparable to Ni-MH for cold performance. The Amazon listing feels intentionally misleading saying "Not Alkaline/Ni-MH Batteries". Well they aren't Lithium batteries either.

          For what it's worth, I've used Li-ion batteries(18650, 3400 mAh) in my headlamps for years in all conditions(NH48x12) and love them and have never had any problems. But Li-ion batteries are also the batteries that can fail catastrophically if they charge bad or get beat up. "Vent-with-flame" is the technical term, I believe, for this poisonous explosion. The small size of AAAs combined with a no-brand chinese battery plus a weird looking built in charger(has to be reducing capacity to include that) make me a little nervous about these. I researched my batteries pretty well and bought a quality charger. If I were you I would do more research on this.

            Don't be this guy...

            What follows is a report, prepared by DEG, of recent missions carried out by Forest Rangers in the Adirondacks.

            Franklin County
            Town of Harrietstown

            Wilderness Rescue: On April 1 at 5:30 am, DEG’s Ray Brook Dispatch received a call from a woman on the summit of Loon Lake Mountain stating that from her position on the fire tower she could see an open flame zig-zagging quickly through the woods in the general direction of the trail leading to the tower. Forest Ranger Beaver Dundee quickly responded to the Adirondack Regional Airport to be transported by helicopter to the incident location with a bucket of water and located the source of the blaze which stated “help! My head is on fire!”. After dousing the heady inferno, Forest Ranger Dundee administered first aid to the victim, a man from Newfoundland, Canada, who mentioned his piss-poor internet-ordered batteries had exploded and ignited in his headlamp. The man was brought to the Lake Placid hospital for further treatment and re-education.

              Ha ha! You got me there! For a while there I thought you were serious. It got me to go back and read the Forum rules which I will consider my punishment for fooling around.

            I came across this which is interesting and somewhat scary. So basically these batteries are constant RF noise emitters... probably fine for a headlamp application, but be very careful when combining with other radio devices. The link below is about the problems associated with avalanche transceivers, but I could imagine these batteries might cause issues with things like GPS receivers and PLB type devices as well.
