This paper discusses and explains to the reader about the concept of battery and various ways to protect the life of the batteries for effiecient use of components.

Battery: a battery is a electrochemcical cell that in enclosed and protected in material that can be charged electrically to provide a static potential for power or release electrical power when needed.

The basic component of battery is that it has an anode, cathode and electrolyte which is like having a positive side, one negative and fluid filled which provides charge in between the two. Hence it is produces electricity through chemical reaction. A battery is a like a storage of power and energy which can be used whenever required. There are different types of battery that are used for different purposes.

Categories: A battery can only be classified into two types of categories namely primary battery and secondary battery. The primary battery is one that needs to be discarded once it has converted its chemical into electricity, while a secondary battery after its usage can still be reconstituted by passing electricity back through it. Hence it is also called storage or rechargeable battery.

Few of the many different kinds of batteries alongwith their basic features are given below:

  1. Sealed Lead Acid or SLA: these are highly cheap batteries that provide charge for about 3 years. And generally is used in backup emergency power source.
  2. Nickel- Cadium (Ni-Cd) Battery: this is also relatively inexpensive and widely available in the market. This provides charge whose consumption is fast and even discharge happens quick. It is used in appliances, audio-video equipments and toys.
  3. Nickel- Metal Hydride (Ni-MH): these batteries are widely used in laptops, camera, cellphones and offers battery life of about 2.5 hours to 4 hours. Its power capacity is about 1.2V.
  4. Lithium- Ion (Li-Ion)battery: this is the battery which is highly safe and stable and provides highest energy capacity. Hence is widely used for various appliances, toys, laptops, cellphones. The advantage of Lithium battery is that it has slow self- disclosure.

The battery comes with a finite life due to the unwanted chemical or physical changes that occur within the battery. This could also involve loss of elements and/or leakage of chemicals. Such changes are irreversible and often drastically affect the electrical performance of the cell. Preventing or reducing the chances for these unwanted

chemical reaction is the way for ensuring that battery life can be extended. This is entirely at the discretion of the user using the battery. The different ways to ensure battery’s long lasting life are as follows:

  •   Avoid Disassembling: try not to dissemble the parts of battery, toxic substances can prove dangerous at times. Or remove any protective layering fom the battery.
  •   Short-circuit: avoid attempting to short-circuiting the battery, it may cause heat and explosion is high possibility.
  •   Expsoure: Avoid putting the battery under the exposure of sun, water which may increase the temperature or put pressure on the cell and making chemicals react.
  •   Appliance specific: use the battery which is specifically designed for it. Changing

    the objects need and type of battery needed can be hazardous and may lead to explosion, fire or emmission of toxic fumes. Read the “type” of battery needed and use the same.

  •   Temperature: at the level of user, it is necessary to ensure that the temperature wherein the battery is kept is at the optimal room temperature, neither hot nor cold temperature is preferred for the functioning of the battery. Store it in a cool, dry place.
  •   Unsuitable Charging methods: overloading a cell during the discharge causes heat making many changes in chemical make up and allowing damage risks.
  •   Soldering : Never solder anything directly to a battery. This can destroy the safety features of the battery by damaging the safety vent inside the cap.
  •   Polarities: it is to be ensured that the battery’s when inserted that their polarities are never reversed as it may cause swelling or rupture thereby causing permanent damage.
  •   Unsuitable Chargers: specific charger should be used to charge. The battery discharge capacity needs to be under consideration before charging is considered.
  •   Over-charging at higher currents and reverse charging: never reverse charge or over charge with high current as it causes rapid gas generation causing the battery to swell and burst.
  •   Installation zone: avoid installing battery in an airtight battery compartment as gases like oxygen and hydrogen are released making the presence for source of ignition.
  •   Old and new battery usage: old, new battery usage needs to be avoided as difference in characterstic values may affect the appliances.
  •   Electrostat Discharge Bag: bags that are meant to protect components from electrostat discharge should be avoided as they are conducive in nature increasing the probablity for short-circuit.
