Dependable
"These are my batteries of choice. Lithium Iron Phosphate is the safest lithium ion chemistry. They do not have the overheating problems the 3. 7 volt batteries have. They are safe enough to not need a protection circuit. The listing above does use the word ‘protected’, but that does not apply to these LiFePO cells."
Fixes the RCR123A voltage issue
"Most RCR123A (rechargeable 123A size) batteries put out 3. 7vDC, which means many flashlights cannot use them as they will shut off when the voltage exceeds 3. 1vDC or so. This is 3volts, so does not have this limitation. Been using it for six months and life is about the same. I love the fact the charger is built right in, I can charge it from any micro-USB charger."
Q&A
- Will these replace LFP123A 3.2V 600mAhr rechargeable? I have the k2 battery in a personal air machine.
- We do not know much about the battery you are referring to but if the battery you wish to replace is a 3.2V battery and is a Lithium Phosphate Iron or LiFePO4 battery then yes, this one should work fine.
- This is a question for Bud E, I guess. He says 'it lasts about as long'...as what? A CR123? Trying to figure out how a 3.2v cell with 450mAh lasts as long as a ~1600 mAh 3.0v cell. Not saying it doesn't, but how? I would like to use these.
- This is a LiFePO4 battery which has a lower voltage than a standard lithium ion battery. A non rechargeable battery will always give you a longer run time over a rechargeable battery. A non rechargeable CR123 ranges between 1400-1550 mAh - where as a rechargeable will provide less than half that. If you are looking for longevity, I would suggest a non rechargeable battery, but if you are looking for the savings of using a rechargeable you will need to recharge more often than you replace a primary battery. Please feel free to ask additional questions if I did not answer your question sufficiently.
- What Voltage setting do I use on an Nitecore NEW i2 charger for these batteries?
- This charger has an automatic current selector. I don't believe you should have to do anything. It is a smart charger so should take care of selecting the chemistry and and charge. "The smart technology contained within this charger automatically detects the chemistry and voltage of your batteries, displaying detailed information on an easy to read LED display. The i2 is compatible with most popular Li-ion chemistry cells, as well as standard sized NiMH and NiCd rechargeable batteries."
