1.5V rechargeable Li-ion battery

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.

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.

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.

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.

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.

It takes about 3 hours to fully charge AA battery and about 2 hours to fully charge AAA battery using charger KT-CPH-57.
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.

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.

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.
