RCR123A rechargeable CR123A batteries are a replacement for standard CR123A batteries in many applications but NOT ALL. Caution must be exercised as these cells are naturally rated 3.7V, not 3V as is a standard CR123A which reads approx
3.2 v~3.3v when new.
Several Nitecore & other brand flashlights use the RCR123a 3.7v as their elecronic circuits have broad voltage operating range often capable of using multiple battery types such as RCR123a, CR123a & 18650 cells.
RCR123A cells are typically about 1mm longer than is standard so if you're using 2 in series you need to be aware that they'll be 2mm longer in total - this is not a problem for most devices as most devices use a spring contact for just this reason.
ALWAYS check your devices operators manual if uncertain as to wether or not you're device is suited to operating on Li-Ion RCR123a batteries. RCR123a cells should only be charged in li-ion chargers specifically designed for these type of batteries.
TECHNICAL INFORMATION : Peak voltage of a 3.7V Li-Ion RCR123A batterywil measure approx 4.2V when fully charged & is considered as flat & shut off a flashlight at approx 2.7v . In comparison the peak voltage of a new standard 3V Lithium CR123A battery (non rechargeable ) is approx 3.3V.
Frequently Asked Questions & Tips
What is the difference between Lithium batteries and Lithium Ion (Li-Ion) batteries?
There are several important differences. The practical difference between Lithium batteries and Lithium-ion (Li-ion) batteries is that most Lithium batteries are not rechargeable but Li-ion batteries are rechargeable. From a chemical standpoint Lithium batteries use lithium in it's pure metallic form. Li-ion batteries use lithium compounds which are much more stable than the elemental lithium used in lithium batteries. A lithium battery should never be recharged while lithium-ion batteries are designed to be recharged hundreds of times. Lithium-ion batteries also require sophisticated chargers that can carefully monitor the charge process.
What are the advantages of Lithium Ion batteries compared to other rechargeable batteries?
Lithium-ion batteries have several advantages: They have a higher energy density than most other types of rechargeables.
This means that for their size or weight they can store more energy than other rechargeable batteries. They also operate at higher voltages than other rechargeables, typically about 3 volts for lithium-ion vs. 1.2 volt
for NiMH or NiCd. This means a single cell can often be used rather than multiple NiMH or NiCd cells. Lithium-ion batteries also have a lower self discharge rate than other types of rechargeable batteries. This means that once they are charged they will retain their charge for a longer time than other types of rechargeable batteries.
NiMH and NiCd batteries can lose anywhere from 1-5% of their charge per day, (depending on the storage temperature) even if they are not installed in a device. Lithium-ion batteries will retain most of their charge even after months of storage.
What are the disadvantages of Lithium Ion batteries compared with other rechargeable batteries ?
Lithium-ion batteries are more expensive than similar capacity NiMH or NiCd batteries. This is because they are much more complex to manufacture. Li-ion batteries actually include special circuitry to protect the battery from damage due to overcharging or undercharging. They are also more expensive because they are manufactured in much smaller numbers than NiMH or NiCd batteries.
Are Lithium Ion batteries available in standard sizes like AA , C or D cell size?
Lithium ion batteries are not available in standard cells sizes (AA, C and D) like NiMH and NiCd batteries.
What is the best way to store Lithium Ion batteries?
Lithium-ion batteries can hold a charge for many months. It is best to store a lithium-ion battery with a partial or full charge. If the battery is going to be stored for several months it's a good idea to take it out and recharge it after a few months.
Better yet would be to actually use the battery every few months and then leave it partially or fully charged.
