Q

Is a charger for nickel metal hydride batteries (Ni-Mh) appropriate for these batteries?

A
  • 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.

Will they fit a Streamlight Microstream?

Q

Can you use these batteries in cordless phones ?

A
  • 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. Perhaps connecting them in parallel would be slightly functional, but it would not be the right thing to do. 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

Q

do these work with peak eiger led flashlights? are they non-imr? thanks!

A
  • 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.

Q

Can you give me the exact diameter in millimeters?

A
  • 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.

Q

How well do these operate in low temp (E.g. 11F-40F) freezing conditions?

A
  • 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.

Q

The battery that came with my ultratac k18 flashlight is a 3.7V Li-ion 10440 350 mAh. can i use these if the mAh is different?

A
  • 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.

Q

can you use these batteries in a remote control

A
  • 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.

    Perfect. Make sure you have a charger specifically for Li Ion batteries.

    Not so sure about these. Bought for a flashlight that specifically calls for 10440 batteries, I don't think they have PCB, may have blown up my new flashlight. I'm going to talk to the flashlight seller first.
