Q:

What is the difference between lithium 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:

Is the product really the lithium battery? Is its voltage really 1.5V?

A:

Absolutely no doubt about that. This is a new technology that has obtained patent (patent number: ZL200820043879.8) issued by the Chinese government. This product has gone through years of technical improvement and rigorous performance testing. It has achieved very satisfactory performance parameters. So users can be assured.

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 KENTLI lithium polymer battery be in common use?

A:

The 1.5V universal polymer lithium-ion batteries are the major research result of KENTLI Electronic Technology Co., Ltd. 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:

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 KENTLI 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; KENTLI PH5 battery: 760mah * 3.7V * 2 = 5624mwh; it can be seen that the capacity of KENTLI lithium batteries is nearly three times that of lithium iron phosphate in the practical application.
