Q：What is the difference between lithium rechargeable batteries and other rechargeable batteries?
A：First of all, this product belongs to the “polymer lithium ion battery,” namely “lithium battery “. Whereas the “rechargeable battery” refers to nickel-metal hydride or nickel-cadmium batteries, which are fundamentally different. Compared with NiMH or NiCd batteries, the lithium battery has such characteristics as high energy density, long cycle life, no memory effect, quick charging speed, ultra-low self-discharge, light weight and environment-friendly. In other word, the phone battery we use now is basically the lithium battery, which is well understood. The phone battery is also developed from nickel-cadmium and nickel hydrogen batteries. “Lithium battery” represents the best battery energy technology at present.
Q：Before that, is there no AA or AAA rechargeable lithium battery?
A：All along, AA or AAA batteries have no lithium batteries in real sense, mainly because the electronic devices on the market using standardized batteries are all designed based on the voltage characteristics of dry batteries (Single voltage of 1.5V). Compared to the traditional standardized batteries, lithium-ion battery’s output voltage is higher (Single voltage of 3.7V). This unique chemical characteristic makes it, the best contemporary energy, have not been possible to enter this field, resulting in serious deficiencies of lithium-ion rechargeable battery in the application field of standardized cylindrical battery.
Q：How can Lithium Polymer Battery be in common use?
A：The 1.5V universal polymer lithium-ion batteries are the major research after years of exploration and research in seeking optimal power solution to portable electronics. It adopts the voltage conversion technology, converting the output voltage of 3.7V into 1.5V, which is fully compatible and alternative to traditional batteries. It has completed a great creation in the field of traditional standard batteries, making the lithium battery step forward to be universal.
Q：What is the difference between polymer lithium ion battery and ordinary lithium ion battery?
A：According to different electrolyte materials, lithium-ion batteries can be divided into polymer lithium ion battery (PLIB), and Li-ion battery (LIB). Ordinary lithium-ion battery refers to liquid lithium battery. In contrast, polymer lithium-ion battery has such characteristics as high energy density and good safety performance. Its quality increases by 20% compared with ordinary lithium-ion (liquid) battery.
Q：How long does it take to charge batteries?
A：It takes about 3 hours to fully charge AA battery and about 2 hours to fully charge AAA battery.
Tips: Due to the special charging characteristics of lithium battery, when the charging time reaches half of the entire charge cycle, the battery has reached more than 85% of the full electric quantity. So in the case of emergencies, it just need half the charging time, thus saving your valuable time.
Q：What does the dual voltage of 1.5V / 3.7V on the battery label mean?
A：There are two sets of output voltage on the positive electrode of lithium batteries. The protruding one of 1.5V is universal battery voltage, users can use it normally, and the other is 3.7V in the groove, which is used to charge the battery.
Q：Why the product is marked of mWh rather than mAh?
A：mWh represents “milliwatt hour”, on behalf of the battery capacity. It is labelled in accordance with the new labeling specifications of lithium-ion batteries. mWh = mAh * voltage.
Q：What is the difference between lithium iron phosphate battery and universal polymer lithium battery?
A：The differences lie in:
1) Voltage: the voltage of lithium iron phosphate battery is 3.2 V. When fully charged, its actual voltage is 3.6 V or so. Such a high voltage is beyond the limit voltage of the appliances using AA or AAA universal battery. So it is easy to damage the appliances (note: this is why the businessman has repeatedly remind users that the battery fully charged should be placed more than 1 hour until the voltage drop, then they can use); universal lithium battery uses intelligent voltage transformation technology, with the constant voltage output voltage of 1.5 V, to ensure the standard voltage of the appliances. (You can check the input voltage parameters on the labels of electrical appliances) Note: the use of this product is like the use of ordinary dry batteries, don’t need to add another bit bucket!
2) Security: Strictly speaking, lithium iron phosphate battery cannot be considered as “batteries”, it is just a cell, without protection circuit; uinversal lithium battery uses multiple intelligence protection circuit preventing overcharge, over discharge, short circuit, overheating, very safe to use. This is also a reason why the cost of the product is higher. Note: lithium iron phosphate battery, because of no protection circuit, have been over discharged when many electrical equipment reach the lowest limit voltage. This is why businesses repeatedly remind users that: Do not charge the battery until it is completely discharged!
3) Capacity: generally, the highest capacity of lithium iron phosphate battery is 600mAh. Its nominal voltage is 3.2V, to be used with bit bucket. Take the electrical equipment using two AA batteries for example. Lithium iron phosphate battery: 600mAh * 3.2V * 1 = 1920mWh; Battery: 760mAh * 3.7V * 2 = 5624mWh; it can be seen that the capacity of lithium batteries is nearly three times that of lithium iron phosphate in the practical application.
Q：What is the concept of the product compared with the ordinary disposable batteries?
A：The product uses polymer lithium cells, which can be recycled 500 to 1000 times. The full charged electricity once is equivalent to that of 2 to 5 batteries. It is no exaggeration to say that a universal lithium battery is equivalent to 1000 to 1500 alkaline batteries, 5000 to 6000 ordinary KK batteries. That’s economical and environment-friendly.
Q：Can we charge other common rechargeable batteries with the special lithium battery’s charger? Or charge universal lithium batteries with ordinary NiMH battery’s charger?
A：No, you can’t! Because charging voltage is different, lithium battery charger is much more complex.
Q：How many mAh is the AA/PH5 battery of 2800 mWh equivalent to?
A：As this is a lithium polymer battery with nominal voltage of 3.7V, and batteries capacity of 760 mAh, when the voltage is converted into the output voltage of 1.5V, it will be more accurate to calculate in “mWh” (power) according to the latest national labelling standard. But compared with the nickel-metal hydride battery, when 1.2 V is divided by 2800 mWh, it is equivalent to more than 2330 mAh. But because the universal lithium is a constant voltage output, the efficient capacity can be released completely, so the stronger battery life of devices using larger electricity reflecting is several times stronger than that of the nickel-metal hydride batteries, or even ten times more.
Q：Is the battery safe?
A：It is very safe, because there are multiple protection mechanism inside the battery. If the voltage conversion circuit is damaged, protection circuit will truncate the output, and the output voltage will be zero.
Q：How about the 1.5 V AA rechargeable lithium battery?
A：Batteries of the AA / AAA rechargeable lithium ion are the best on the universal batteries market, according to the “best” does not mean that the battery manufacturing technology so mystical, but the materials inside the battery – “cells” are changed, used polymer lithium ion cells, while the polymer lithium ion represents the contemporary the most optimal battery technology, so we said the battery is the “best”. , of course, the “best” is relative, lithium batteries due to a high energy, no memory effect, long cycle life, light weight and fast charging itself unique performance advantage has become the mainstream of the current battery power, and all of these “performance advantages of lithium battery is also relative to Ni-MH batteries, we have seen, in the high-end electronic products market is almost can not see the figure of Ni-MH batteries, replaced by lithium batteries; And in the field of general battery, namely we are the most common AA /AAA standard battery system development has been to stay in “nickel metal hydride phase,” battery is precisely at this time, apply a “voltage transformation technology” to “introduction” general batteries, lithium-ion batteries for contemporary general battery and battery technology “synchronous”. We can imagine, with the development of science and technology, technology updates, there may be a fuel cell in the future, better batteries energy sources such as nuclear power battery, but in the present stage of batteries, lithium batteries will occupy the mainstream market in a long time.
