ZI7 Alkaline Batteries AAA (10 pcs.)

Production of Japanese company Hitachi/Maxell, long-service life, safe for the environment, alkaline batteries, which do not contain mercury and cadmium

Set of 10 batteries, which are kept in a special box

Beautiful design

Once you see battery Mi Rainbow, you will immediately like them! 10 different bright colors that, to some extent, enliven batteries. Now you can easily distinguish old from the new battery, and also choose your favorite color of batteries for your home devices. Japanese company Hitachi Maxell, which is a manufacturer of Mi Rainbow, will provide you with reliable, safe and long lasting batteries. Updated engineering, both internal and external parts of the battery. Mi Rainbow — is example of manifestation of love for life

• 4 levels of safety (leakage protection)
• 7 years — storage life for 7 years from date of production
• 10 batteries in a special box
• Long service life
• Production of Japanese company Hitachi Maxell

Mi Rainbow stands out not only for its bright colors. The core of batteries, manufactured by Japanese company Hitachi Maxell, compared to conventional carbon fiber batteries, considerably better and are more reliable. Thanks to patented stretching technology relatively to the thick steel shell, the capacity of Mi Rainbow compared to the previous generation of alkaline batteries has increased, although their size has not changed. Furthermore, by applying the technology of refilling, their high-density increases contact effect of manganese anode electrode, thereby providing a strong output. As a result, the period of use of batteries in the remote control, flashlight and other devices has become longer.

4 levels of safety

In order to prevent leakage of batteries, we have updated the design of the battery. Now they are more resistant to water absorption, and the material of sealing ring of the new model is more durable and reliable. If batteries are stored in a damp environment, in  high-temperature conditions or other adverse conditions, they are not getting deformed and will not be embrittled. Nickel plating of an all-steel shell of batteries compared to conventional steel and iron shells have better resistance to pressure, and application of the technology of high-density manganese anode electrode increased battery leakage protection level. Bottom insulation ring is designed to prevent from short circuit, and automatic pressure relief valve protects your device from the occurrence of adverse situations.

High level of safety

We have applied a more rational distribution of zinc dust over the cathode. At the same time, the presence of alloying element in the zinc dust has lowered the risk of leakage and improved safety level of batteries.

Bottom insulation ring

The design of the lower insulating ring separates cathode from an anode, preventing the possibility of a short circuit.

Manganese anode electrodes of high density

Conventional batteries have only 3 manganese rings, but Mi Rainbow equipped with four such rings. The more manganese rings, the stronger erosion control resistance of alkali protection, and thus significantly reduced the risk of batteries leakage.

Safety valve

In the event of a short circuit, reverse polarity, or other dangerous situations (as a result of improper use of the battery), as a result of which significantly increases the internal pressure of the battery, the safety valve automatically opens and reduces it. Thus, preventing the probability of rupture of the battery.

Shelf life — 7 years

Longer service life

Shelf life is an essential requirement for batteries because for a long time they can maintain charge and will help you out at the right time. The unique composition of batteries extends their reliable and stable storage, reducing the level of self-discharge. Now, thanks to the effective work of the battery, you can have fun by spending leisure time with your favorite devices.

• Wireless keyboard
• Remote control
• Wireless mouse
• Flashlight
• Alarm clock

Mi Rainbow — recognize new and old batteries at a glance

Distinguish old batteries from the new, and also choose your favorite color of batteries for your home devices. For example, choose yellow batteries that resemble the sun, for your alarm clock, and red for the remote control. Note that, how our colorful batteries will decorate your home devices.

Special and convenient box of 10 batteries

Usually, batteries have disposable paper packaging, which is typically difficult to open, and not so comfortable to store therein remaining batteries. This is an old problem, to which no one paid much attention. So we invented and created a very practical box, in which is comfortable to store new batteries. It has a matt coating, on which background stands out bright and colorful multi-colored batteries Mi Rainbow.

Ecological Design

Let us make our lives more safe

Environmentally safe batteries for a safer life! We have passed rigorous certification standards in Europe, because Mi Rainbow does not contain mercury and cadmium, and are completely non-toxic. There is no need to store batteries separately and after use, you can safely dispose them along with all household waste.
