In 1798, Alessandro Volta invented the Voltaic Pile, which could make devices work without the use of electricity but with the use of copper zinc discs submerged in acid salt solution.

Then over time, courtesy of the the great minds of inventors John F. Daniell, Georges Leclanche, at Carl Gassner, batteries evolved to what we know of them today.

Come 1898, Conral Hubert invented the electric hand torch or the flashlight and needed batteries for it. Thus, he acquired the National Carbon Company and sold the first flashlights & dry cell batteries. And these batteries are the same batteries we now know as Eveready Batteries.

The Eveready Cat

In the 1920s and 1930s, a lot of very endearing and heart-warming Eveready advertisements came out in newspapers, catalogues, magazines, posters and even calendars!

The most popular visual of which, was a little girl holding a flashlight looking after a litter of 9 kittens.

This was where the Eveready logo was depicted, the cat with nine lives.

Similar to Eveready having durable and lasting battery life, thus, this became the symbol of Eveready.

Eveready in the Philippines

From the 1920s to the 1950s, the world discovered the convenience and service Eveready could give.

In the 50s, alongside various new inventions, Eveready Batteries became key to using various wonderful devices and contraptions to work properly without the use of electricity, anytime, anywhere.

For Filipinos, the 1950s also marked a great change in their lives.

On August 13, 1951, National Carbon Company was founded, the company known to be the makers of Eveready batteries.

Not long after, Eveready has been with Grandma, Pop, Inday and even with Junior in tuning in with their transistors running with Eveready Batteries, listening to Kuwentong Kutsero, Tawag Ng Tanghalan, pati ng Camay Theater.

And on October 14, 1955, the first battery plant was opened in Mandaluyong City.

Then, on October 21, 1962, National Carbon Company Philippines became Union Carbide Philippines.

And 1971, the second battery plants was opened in Mandaue, Cebu. A testament to the growing industry.

This was the same year that Eveready was known to be the battery that has power and lasts longer.

In March 1987, the name was again changed into Eveready Battery Company Philippines, Inc. and still continues to provide service, power and light to the Filipino People.

Eveready, being the forefront in the battery & flashlight industry launched several products to further serve the need of the consumers.

There was the Eveready Gold Alkaline Battery, a very reliable heavy duty battery ideal for high-powered devices. Eveready Gold is the best Eveready battery because it lasts up to 3x longer than ordinary Eveready carbon zinc batteries.

There was the Eveready Rechargeable Batteries & Chargers for those heavy-users of batteries and this can be charged 100s & 100s of times.

Also, Eveready has several LED Flashlights that are affordable with the same trusted quality ideal for use at home, at work, on the road and for outdoor.

Eveready utilizes LED bulbs aware of the many benefits it brings. As it gives a bright white light, it's virtually unbreakable that you will never need to replace the bulb and most of all, it is battery efficient.

It is indeed a long history Eveready has. And it lasted for 110 continuing years because it incessantly and consistently renders products and services through all these years. Eveready is genuinely forever ready to make our lives beyond comfortable and bright.

Eveready and the Environment

It is a known fact that Eveready not only provides high quality products but also, Eveready takes into high consideration the welfare of our environment.

Eveready pioneered in manufacturing batteries without adding chemicals such as Mercury and Cadmium that is harmful to our health and to the environment.

This truly is an unwavering service to the Filipino People.


A Battery is ..

  • A device that stores energy until it is need to do work.
  • A device that convert a chemical energy into electrical energy.
  • Electrons flow (electric current) through the wire from the negative to the positive electrode powering the light bulb as they pass through it.
  • The anode (-) gives up electrons in a process know as oxidation during discharge.
  • The cathode (+) absorbs electrons in a process known as oxidation during discharge.
  • Ions shuttle electrons through the electrolyte from the cathode to the anode completing the circuit.
  • The electrolyte is the source of oxygen fro the oxidation and reduction reactions.


Read the instructions on your device before installing batteries. Make sure to insert the batteries properly, following the symbols showing you the correct way to position the positive (+) and negative (-) ends of the batteries.

Replace batteries with the size and type specified by the device’s manufacturer. Remove all used batteries from the device at the same time, then replace them with new batteries of the same size and type.

Inspect device’s battery compartment every few months to be sure batteries are not leaking.

Keep battery contact surfaces clean by gently rubbing with a clean pencil eraser or cloth.

Don’t recharge a battery unless it is specifically marked “rechargeable.” Attempting to recharge a primary (non-rechargeable) battery could result in rupture or leakage.

Don’t mix old and new batteries, or mix different types or makes of batteries. This can cause rupture or leakage, resulting in personal injury or property damage.


Don’t dispose of Eveready batteries in a fire – they may rupture or leak.

Don’t carry loose Eveready batteries in a pocket or purse with metal objects like coins, paper clips, etc. This could potentially short-circuit the battery, generating high heat.



Store batteries in a dry place at normal room temperature. Remove batteries from devices that will be stored for extended periods.

Don’t store batteries or battery-powered devices in hot places – elevated temperatures increase the self-discharge of batteries.


Does a battery charge itself if placed under the heat of the sun?

Does it charge if placed inside the freezer?

Do batteries discharge even if the devices are turned off?

Does a new battery recharge an old one if used together in one device?

Can “shaking” or “tapping” revive a battery?

Are the fluids excreted by a battery poisonous?

Why does a battery leak?

Does a battery really explode? Serious explosion?


Non-rechargeable property of Carbon Zinc Batteries
  • Subjecting batteries under the sun’s heat DO NOT recharge the batteries.
  • Batteries also undergo stress during prolonged use. Allowing batteries to rest in room temperature will still allow slight recovery of power.
  • Excess heat (or exposure to direct fire) will cause the chemicals inside to evaporate or generate gas,and build-up pressure that will lead to explosion.


Non-rechargeable property of Carbon Zinc Batteries
  • Under low temperatures, batteries DO NOT recharge themselves, though CZ batteries live longer on standby at 20oC.
  • Placing batteries in freezers is discouraged since this causes moisture to build-up on the metallic parts and eventually cause corrosion and early deterioration.


Self-discharge property of Batteries
  • Yes. Even if the device is off, batteries have a self- discharge property.
  • The terminals and primary power circuit of devices does, to a certain extent, cause slow discharge of the batteries. This is the reason why batteries should not be allowed to standby inside devices if not used for a prolonged period of time.


Non-rechargeable property of Carbon Zinc Batteries
  • Yes. A “charging” effect will happen if new and old batteries are used in one device or system. Since Carbon Zinc or Primary Batteries resist incoming power during charging, heat will build up and the batteries could leak or explode.
  • The use of old batteries also affects the efficiency of the batteries being used. Spent batteries have high internal resistance, preventing the newer one from delivering its maximum available power.


Non-rechargeable property of Carbon Zinc Batteries
  • Shaking or tapping spent batteries DOES NOT restore the power or life of the battery. This practice is not encouraged, especially tapping, because this may potentially compromise the seal of the battery. Denting may also occur which leads to earlier deterioration of batteries and leakage.


A Carbon Zinc Battery’s acidic system
  • Just like any other household chemicals that we use like rat poison and insect-repellent chalks, battery fluid is most hazardous when ingested. Physical contact with the liquid will cause skin irritation, though to a lesser degree compared to cleaning agents like muriatic acid and liquid sosa. It is still best to avoid contact and dispose of leaking batteries. If contact may occur, immediately wash with soap and water. If ingested, contact the doctor for proper treatment.


Proper use and storage of batteries
  • The Carbon Zinc battery construction utilizes a zinc metal can to contain the ingredients. This zinc can is also a reactant to the discharge reaction. If a battery is abused, the zinc can will perforate and allow the liquid inside to flow out of the can. The fluid will find its way out through the seals of the battery like the top and bottom cover spins.
  • To prevent leaking, do not allow the battery to stay inside a device for a prolonged period of time. Also, do not attempt, by any means, to recharge.


Safety precaution on battery disposal
  • When batteries are recharged and disposed in fire, pressure builds up internally. When the pressure is high enough, such that the seals of the battery cannot withstand it, it will eventually loose its integrity and ‘explode’. However, this explosion is not as serious as a real bomb. The danger of this ‘explosion’ is that the acidic liquid inside the battery will be spread within several feet away due to the released pressure. This hot acidic liquid might come in contact with eyes or any part of the body.
