Xiaomi ZI7 Mi Rainbow AAA LR03 Alkaline Battery
Overview
Production ofย Japanese company Hitachi/Maxell, long-service life, safe for the environment, alkaline batteries, which doย not contain mercury and cadmium
Set ofย 10ย batteries, which are kept inย aย special box
Beautiful design
Once you see battery Miย Rainbow, you will immediately like them! 10ย different bright colors that, toย some extent, enliven batteries. Now you can easily distinguish old from the new battery, and also choose your favorite color ofย batteries for your home devices. Japanese company Hitachi Maxell, which isย aย manufacturer ofย Miย Rainbow, will provide you with reliable, safe and long lasting batteries. Updated engineering, both internal and external parts ofย the battery. Miย Rainbowย โ isย example ofย manifestation ofย love for life
- ♦ 4ย levels ofย safety (leakage protection)
- ♦ 7ย yearsย โ storage life for 7ย years from date ofย production
- ♦ 10ย batteries inย aย special box
- ♦ Long service life
- ♦ Production ofย Japanese company Hitachi Maxell
Miย Rainbow stands out not only for its bright colors. The core ofย batteries, manufactured byย Japanese company Hitachi Maxell, compared toย conventional carbon fiber batteries, considerably better and are more reliable. Thanks toย patented stretching technology relatively toย the thick steel shell, the capacity ofย Miย Rainbow compared toย the previous generation ofย alkaline batteries has increased, although their size has not changed. Furthermore, byย applying the technology ofย refilling, their high-density increases contact effect ofย manganese anode electrode, thereby providing aย strong output. Asย aย result, the period ofย use ofย batteries inย the remote control, flashlight and other devices has become longer.

4ย levels ofย safety
Inย order toย prevent leakage ofย batteries, weย have updated the design ofย the battery. Now they are more resistant toย water absorption, and the material ofย sealing ring ofย the new model isย more durable and reliable. Ifย batteries are stored inย aย damp environment, inย ย high-temperature conditions orย other adverse conditions, they are not getting deformed and will not beย embrittled. Nickel plating ofย anย all-steel shell ofย batteries compared toย conventional steel and iron shells have better resistance toย pressure, and application ofย the technology ofย high-density manganese anode electrode increased battery leakage protection level. Bottom insulation ring isย designed toย prevent from short circuit, and automatic pressure relief valve protects your device from the occurrence ofย adverse situations.

- ♦ Insulating ring
High level ofย safety
Weย have applied aย more rational distribution ofย zinc dust over the cathode. Atย the same time, the presence ofย alloying element inย the zinc dust has lowered the risk ofย leakage and improved safety level ofย batteries.
Bottom insulation ring
The design ofย the lower insulating ring separates cathode from an anode, preventing the possibility ofย aย short circuit.
Manganese anode electrodes ofย high density
Conventional batteries have only 3ย manganese rings, but Miย Rainbow equipped with four such rings. The more manganese rings, the stronger erosion control resistance ofย alkali protection, and thus significantly reduced the risk ofย batteries leakage.
Safety valve
Inย the event ofย aย short circuit, reverse polarity, orย other dangerous situations (asย aย result ofย improper use ofย the battery), asย aย result ofย which significantly increases the internal pressure ofย the battery, the safety valve automatically opens and reducesย it. Thus, preventing the probability ofย rupture of the battery.
Shelf lifeย โ 7ย years
Longer service life
Shelf life isย anย essential requirement for batteries because for aย long time they can maintain charge and will help you out atย the right time. The unique composition ofย batteries extends their reliable and stable storage, reducing the level ofย self-discharge. Now, thanks toย the effective work ofย the battery, you can have fun byย spending leisure time with your favorite devices.

- ♦ Remote control
- ♦ Wireless mouse
- ♦ Flashlight
- ♦ Alarm clock
Miย Rainbowย โ recognize new and old batteries atย aย glance
Distinguish old batteries from the new, and also choose your favorite color ofย 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 ofย 10ย batteries
Usually, batteries have disposable paper packaging, which isย typically difficult toย open, and not soย comfortable toย store therein remaining batteries. This isย anย old problem, toย which noย one paid much attention. Soย weย invented and created aย very practical box, inย which isย comfortable toย store new batteries. Itย has aย matt coating, onย which background stands out bright and colorful multi-colored batteries Miย Rainbow.
Ecological Design
Letย us make our lives more safe
Environmentally safe batteries for aย safer life! Weย have passed rigorous certification standards inย Europe, because Miย Rainbow does not contain mercury and cadmium, and are completely non-toxic. There isย noย need toย store batteries separately and after use, you can safely dispose them along with all household waste.
