Of course, there are differences:
Actually, there are three batteries of the same size but different performance: AA14500 nickel-metal hydride, 14500 lithium battery and AA dry battery. Their differences are:
1. AA14500 nickel-metal hydride, rechargeable battery. 14500 lithium rechargeable battery. AA batteries are disposable, non-rechargeable dry batteries.
2. The voltage of AA14500 nickel metal hydride is 1.2 volts and reaches 1.4 volts when fully charged. The voltage of the 14500 lithium battery is 3.7 volts and reaches 4.2 volts when fully charged. The nominal size of an AA battery is 1.5 volts, and the voltage drops to around 1.1 volts and is discarded.
3. Everyone has their own application opportunities and cannot replace each other.
The size of AA battery and 14500 battery is the same
14500 means the total height of the battery is 50mm and the diameter is 14mm
AA battery is usually called formerly sex battery or nickel-metal hydride nickel-cadmium battery, 14500 is generally the name of lithium-ion battery
It is a lithium battery with a diameter of 14 mm and a height of 50 mm depending. According to the cell material, it is divided into lithium iron phosphate battery and lithium acid cobalt battery. The voltage of the lithium cobalt oxide battery is 3.7V and the voltage of the lithium iron phosphate battery is 3.2V. The voltage can be adjusted to 3.0V via a battery voltage regulator lithium. Since its external dimensions are the same as AA5# batteries, one 14500 lithium battery and a reserved bucket can be used instead of two AA batteries. Compared with nickel metal hydride rechargeable batteries, lithium batteries have the advantages of light weight, less self-discharge and higher discharge performance. PTherefore, they are widely used by photography enthusiasts in digital cameras and electronic cigarettes to replace nickel-metal hydride. rechargeable batteries.

Comparison of advantages and disadvantages< /p >
The Lithium cobalt oxide is currently the most widely used cathode material for lithium-ion batteries. It has mature technology, stable structure and high specific capacity.It has the advantages of high efficiency and outstanding overall performance; the disadvantages are poor safety and high cost, and it is mainly used for small and medium-sized batteries.
Lithium iron phosphate is an emerging material for the cathode of lithium-ion batteries. It has the advantages of good safety, no explosion andgood cycle performance (up to 2000 times), but its energy density is much lower than that of lithium-ion batteries. that of lithium-cobalt oxide and ternary lithium-cobalt materials. It is more suitable for electric vehicles, power tools and other fields.
The answer you adopted is not complete enough.
There are two types of 14500 lithium batteries, one is 3.2V lithium iron phosphate battery and the other is 3.7V ordinary lithium battery. < /p>
The possibility of universal use therefore depends on whether your device uses one or two AA batteries.
If it is a one-battery electrical device, it cannot under any circumstances be used with 14,500 lithium batteries.
If it is This is a dual battery device, one 3.2V 14500 lithium iron phosphate battery can be used completely when matched with a reserved bucket (dummy battery). Batterylithium iron phosphate 3.7V 14,500 may be universal, but the match is not optimal.
Cannot be used universally, they are the same size.
Since the voltage of the 14500 lithium battery is 3.7V and that of the ordinary No. 5 battery is 1.5V, the voltage is different.
If the lithium battery is replaced, the electrical appliance may be burned and pose a danger.
Is the No. 5 14500 lithium battery durable?
The number of cycles of the lithium iron phosphate battery is more than 2500, and the number of cycles of the nickel-metal hydride battery is about 500 times. , and it has a memory effect. In terms of service life, lithium iron phosphate is much larger than nickel metal hydride, judging from the capacity you wrote, 2300 is greater than 600, which means standby time. Nickel metal hydride is larger than le lithium iron phosphate. If you charge and discharge once a day, the nickel-hydrogen one lasts 500 days, or 1 year, and the lithium iron phosphate one lasts 2,500 days, or 6. years and 310 days. When you buy it, the lithium iron phosphate one will definitely be more expensive than the nickel metal hydride one. Think about it yourself. Durable.
14500 can be recharged. It can be used continuously for 4-10 hours when fully charged and the battery life is solid.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.
