Battery leakage is the electrolyte inside the battery automatically leaks to the outer surface of the battery or battery components.

I. Don't leave batteries in your device if you suspect it will not be used for several months. Many devices don’t power off completely when switched off and, after time, may cause the batteries inside to leak.

II. Don't carry batteries loose in your pocket or purse as they can be shorted by contact with metal objects and may leak, overheat or rupture.

III. Don't mix old and new batteries, batteries of different brands, or batteries of different types in the same device as this may cause the batteries to leak.

IV. Don't attempt to recharge non-rechargeable batteries. This can cause your batteries to overheat or leak.

V. Don't put batteries or battery-powered devices in very warm places. Extreme temperatures reduce battery performance and may also lead to leakage.

VI. Don't remove the battery label, or attempt to take the battery apart, or dispose of in a fire as this may lead to rupture and/or chemical burns.

I. Batteries should be stored in a clean, cool and ventilated place;

II. Appropriate and recommended temperature 50-77℉, humidity 40-65%;

III. Storage time shall not be too long;

IV. Arrange neatly when stored and do not connect the positive and negative poles in case of short circuit.

Batteries with alkaline electrolyte were first developed by Waldemar Jungner in 1899. The modern alkaline dry battery, using the zinc/manganese dioxide chemistry, was invented by the Canadian engineer Lewis Urry in the 1950s in Canada. On October 9, 1957, Urry, Karl Kordesch, and P.A. Marsal filed US patent (2,960,558) for the alkaline battery. It was granted in 1960 and was assigned to the Union Carbide Corporation.

I. Check whether the contact parts of the electric appliance and battery are clean, wipe them with wet cloth if necessary, and load them with correct polarity after drying

II. Do not mix used and new batteries;

III. Disposable batteries cannot be heated or charged;

IV. Do not disassemble the battery;

V. Switch off after using the electric device. Battery should be removed when the electric device is not used for a long time.

Zinc-carbon batteries are used in electrical appliances that consume little energy, such as wall clocks and remote controls. Alkaline batteries are used where long-lasting, constant high-energy output is required, such as in MP3 players, CD players, digital cameras, toys, flashlights, and radios.

The main difference between carbon zinc batteries and alkaline batteries is the electrolyte used; zinc batteries use acidic ammonium chloride, whereas alkaline batteries use basic potassium hydroxide.

* Alkaline batteries have a larger capacity and are more adaptable to high current discharge.

* Alkaline batteries have a longer shelf-life, i.e., in storage, they can retain their capacity longer.

* Alkaline batteries are safer than carbon zinc batteries as the latter are prone to leakages.

Essentially, alkaline manganese dioxide batteries, commonly known as alkaline batteries, are good all-around batteries for everyday electronic devices and last longer than some other types. However, lithium iron disulfide batteries, or lithium batteries, have several distinct advantages over their alkaline counterparts:

* They're designed to last longer, making them a good choice for high-tech and smart devices, and those electronics for which changing the battery is inconvenient.

* They can withstand extremely low temperatures. Lithium can operate without failing in a very cold climate, so it's ideal for outdoor applications.

* Lithium batteries are lighter than alkaline batteries, so they offer an advantage when used with portable devices, especially cordless power tools.

In short, a lithium battery can be used as a high-performing alternative to a standard alkaline battery. However, the benefits come at a cost: Lithium is a more expensive technology, which means a higher price point. These batteries can even outlast the normal lifespan of some inexpensive, noncritical devices, like toys, so the extra cost may not be justified in every case. Also, lithium batteries are restricted as carry-on travel items by some airlines.

Why always Voniko?

No. Place your batteries in a refrigerator will not ‘recharge’ your batteries, increase storage life, or increase your batteries’ power.

1.5 volts, generally 2900mAh.

It converts chemical energy into electrical energy by using manganese dioxide as the positive electrode and zinc cylinder as the negative electrode to power an external circuit.

Batteries go flat as a result of the electrolyte's chemicals drying up within the battery. In the case of alkaline batteries, this is when all of the manganese dioxide has been converted. At this stage the battery is flat.

When an alkaline battery works, i.e. releases power, the chemicals inside create a gas. If this occurs too much, the battery cell may rupture. This is where leakage may occur. Normally, the battery seal prevents this.

Batteries go flat as a result of the electrolyte's chemicals drying up within the battery. In the case of alkaline batteries, this is when all of the manganese dioxide has been converted. At this stage the battery is flat.

Since an alkaline battery is normally sealed, very high pressures can be created within it. This can rupture the seal, resulting in leakage of the contents or even explosion. We recommend that you use Voniko NiMH rechargeables. Paired with one of our customized chargers, they can be recharged hundreds of times.

All single-use batteries must be recycled or taken to a household hazardous waste disposal facility, a universal waste handler (e.g., storage facility or broker), or an authorized recycling facility. If there is no department near you, pls contact info@vonikobatteries.com and our professional customer service will fix your request.

Use the correct size and type of battery specified by the manufacturer of your device.

Not at all. When charging, a large amount of gas will be produced inside the battery, which will increase the battery pressure and result in battery explosion or leakage.

Because the new battery holds high power while used battery energy is less low.The lifespan of the new battery will be shortened when they are mixed. What’s worse, the new battery could make used battery overdischarge, cause leakage and damage electric device.
