No. Ni-Mh chargers are for 1.2v batteries. (plus other issues) Nitecore makes a couple of intelligent universal chargers for most sizes of Ni-Mh, Ni-Cad, and Li-Ion for under $20. Use 2nd generation 2014 version.

It may fit, but the voltage is too high for most aaa flashlights, and might blow your led out.

Very unlikely as many cordless phones use multiple batteries connected in series (usually 3 x 1.2 volt NiHm = 3.6 volts) and were you to connect these in series it would probably burn out the phone. Perhaps connecting them in parallel would be slightly functional, but it would not be the right thing to do. If you can't… see more Very unlikely as many cordless phones use multiple batteries connected in series (usually 3 x 1.2 volt NiHm = 3.6 volts) and were you to connect these in series it would probably burn out the phone.

If you can't find the right pack for your phone, it might be better to buy a pack at the right voltage and power (mAh) and use the connector from your dead battery pack to connect it to your phone. see less

As is they will not work as they are too long for peak eigers. I have several peak eigers and the heads won't screw to the body with this cell. A fenix ld01 works very well. So will an olight i3s if you rip the spring out and trim it down a bit.

Due to the protection, the thickest spot on the battery is 10.6mm. I needed to remove the label, the protection circuit, and line to positive, to fit it in a DQG Tiny AAA Ti, then it's only 10.06mm diameter.

Can't attest to thier operation in those temps, but one thing you may want to consider before buying these (that I overlooked) is that the protective circuitry means extra material. Unless you have a lot (and I mean a lot) of play, these won't fit in a standard 10440 or AAA battery pack. I'd recommend the unprotecte… see more Can't attest to thier operation in those temps, but one thing you may want to consider before buying these (that I overlooked) is that the protective circuitry means extra material.

The battery that come with the Ultratac K 18 is a 1.5 v i order some 3.7V Li-ion 10440 because they are brighter and rechargeable.

I don't know if any remote control uses 3.7 volt battery or not, but I will not try this 3.7 volt battery on any remote control using AAA (1.2 or 1.5 volt) battery. It might just damage the device. This is 10440 Li-ion battery and it just has the "size" of AAA battery.
