What is an alkaline battery?


Alkaline battery is rapidly became the popular choice of designers in the ever-widening field of consumer electronics.Alkaline or Alkaline Manganese Dioxide cells have many advantages over zinc-carbon cells including up to ten times the ampere-hour capacity at high and continuous drain conditions. Also, its performance at low temperatures is superior to other conventional aqueous electrolyte primary cells.Other significant advantages are longer shelf life, better leakage resistance,and superior low-temperature performance. Its more effective, secure seal provides excellent resistance to leakage and corrosion.


What is inside an alkaline battery?


Batteries may be small,but they’re far from simple.They're highly engineered electrochemical cells.Chemical energy is converted to electrical energy by a redox reaction.This process takes place between the three major parts of a battery:the anode,

cathode, and electrolyte. Different types of batteries use different materials for these parts. The materials for these parts are chosen depending on how well they give up or attract electrons, something that must happen for an electric current to be generated.The anode is often a metal,the cathode is a metallic oxide, and the electrolyte is a salt solution that facilitates the ion flow.


How doea a alkaline battery work?


Batteries may seem simple,but the delivery of packaged power is a complicated electrochemical process.Electric current in the form of electrons begins to flow in the external circuit when the device—a light bulb for example—is turned on.At that time, the anode material,zinc, gives up two electrons per atom in a process called oxidation, leaving unstable zinc ions behind. After the electrons do their work powering the light bulb, they re-enter the cell at the cathode, where they combine with the active material, manganese dioxide,in a process called reduction.The combined processes of oxidation and reduction couldn’t occur in a power cell without an internal way to carry electrons back to the anode,balancing the external flow of current.This process is accomplished by the movement of negatively charged hydroxide ions present in the water solution called the electrolyte.Every electron entering the cathode reacts with the manganese dioxide to form MnOO-.Then,MnOO- reacts with water from the electrolyte.In that reaction,the water splits,releasing hydroxide ions into the electrolyte and hydrogen ions that combine with MnOO- to form MnOOH.The internal circuit is completed when the hydroxide ions produced in this reaction at the cathode flow to the anode in the form of ionic current.There,they combine with unstable zinc ions,which were formed at the anode when the electrons were originally given up to the external circuit.This produces zinc oxide and water. This completes the circuit (which is necessary to have a constant flow of electricity) and powers your flashlight.


What is the difference between lithium battery and alkaline battery?


Lithium and alkaline batteries employ different chemistries for maximum performance in different devices.Lightweight and compact,lithium batteries often come in distinctive sizes for use in specific devices.


When should I remove alkaline batteries from the device?


Batteries should be removed from devices/equipment in the below listed instances:

The device is not expected to be in use for several months

The batteries are worn out (to prevent possible damage from battery leakage)

The device is being powered by household (AC) current


Are batteries affected by temperature?


We recommend storing batteries at room temperature in a dry environment.Extreme heat or cold reduces battery performance.You’ll want to avoid putting battery-powered devices in very warm places.In addition,refrigeration is not necessary or recommended.


Can Alkaline battery be recharged?


Only batteries that are specifically labeled “rechargeable” should be recharged.Any attempt to recharge a non-rechargeable battery could result in rupture or leakage.We recommend that you use NiMH Duracell rechargeables.Paired with one of our different chargers,they can be recharged hundreds of times.


How do I clean up after a battery leak?


Follow these tips to clean up after a battery has leaked: Work in a well-ventilated area.Wear household gloves and glasses.Using a toothbrush or cotton swab,remove battery leakage from the electrical contacts.Make sure the electronic device is completely dry before trying a new battery.To avoid future problems,adopt the following practices:

Do not mix and match different battery brands in the same device.

Remove batteries from devices that are being stored.

To clean any leakage of the following battery types,Alkaline, NiCAD and NiMH batteries,use either one tablespoon of boric acid in one gallon of water or a mixture of equal amounts of diluted vinegar or lemon juice with water (50/50 ratio).


Do all alkaline batteries last the same amout of time?


No,different batteries provide different lengths of life and power output depending on the type and amount of chemicals used to compose them.Think of it like cooking a meal:Using different ingredients and amounts make the meal taste different.


Do I have to change all the batteries at the same time?


We do recommend changing all batteries in a unit at the same time.A partially used battery will drain energy from a new one,reducing the total amount of battery power available.


Do your batteries contain mercury?


No,all versions of RISE batteries are mercury-free.We are proud to have voluntarily stopped using mercury in our general purpose batteries (AAA, AA, C, D, and 9V sizes) in 2003.

Our alkaline batteries are made mainly from common metals steel,zinc and manganese and do not pose a risk to health or the environment if they are used and disposed of appropriately.All hearing-aid batteries have been mercury-free since November 2012,in line with The Mercury-Containing and Rechargeable Battery Act.
