  Batteries can be classified as either Primary or Secondary. Primary batteries are designed for a single cycle only, i.e. they’re non-rechargeable. Secondary batteries are designed to be recharged, typically, from 200 to 1000 times. Most commonly used Primary batteries are Zinc Carbon & Alkaline Battery.

How to select the right kind of batteries for your camera’s long life ?

 This time we will talk about batteries. Battery plays an important role in a camera as there is no usage of the    cameras without the battery. In the past mercury-cadmium batteries were used. However since they increase the toxicity levels of environment they have been stopped. Present day scenario the requirement is hi-power and capacity, therefore the industry comes up with better products which are environmental friendly as well.

There has been a major transition in using Alkaline batteries over Zinc Carbon batteries and Nickel-Metal Hydride (NiMH) and Lithium Ion (Li-Ion) over Nickel-Cadmium (Ni-Cd) batteries.


  • Canon uses Lithium Ion or AA batteries in all of their current cameras models
  • Lithium batteries are used mainly due to compact design ( Hi –power ) and are economical ( since they are rechargeable ) as well.
  • AA batteries are used due to easy accessibility.


The SX Series & A 800 series of Canon digital cameras are still using AA dry cell battery  as they are  easily accessible and can be bought from any where, i.e. a store, a kiosk etc.

AA Dry-cell battery


Batteries can be classified as either Primary or Secondary. Primary batteries are designed for a single cycle only, i.e. they’re non-rechargeable. Secondary batteries are designed to be recharged, typically, from 200 to 1000 times. Most commonly used Primary batteries are Zinc Carbon & Alkaline Battery.

The difference between Zinc Carbon and Alkaline battery batteries is the capacity. Alkaline battery is many fold over the capacity of Zinc carbon.

Therefore, I would recommend alkaline batteries for your camera usage.

  • Most commonly used secondary batteries are NiMH (nickel-metal hydride cell), NiCd (nickel-cadmium) and Lithium . However,  NiCd (nickel-cadmium) are not in use anymore.
  • Nickel Metal Hydride (Ni-MH) batteries are the cadmium-free replacement option for NiCad. They have less memory effect than NiCd and thus require less maintenance and conditioning.

* My recommendation normally use the Secondary Battery and keep Primary Batteries in emergency case.

Lithium-ion battery

  • Lithium-ion battery is compact in design and has high energy density therefore readily used in portable devices.
  • In addition to this, Lithium-Ion batteries have no memory effect and do not use poisonous metals, such as lead, mercury or cadmium.
  • Lithium is sensitive material in nature, so Canon had introduced various safety features in their Lithium Ion batteries.
  • Lithium-ion batteries should be partially charged before storing in a cool and dry place.


Some useful Recommendations
  • Sometimes it becomes difficult to have an appropriate environment to store your camera batteries. Therefore, it is recommended to buy a new battery every three years.
  • Old batteries can be used for emergency purposes only.
  • It is recommended to carry an extra battery while you are out on shooting pictures.
  • It is recommended to return the battery to the camera dealer or manufacturer to dispose it off.
  • Do not put the battery to fire easily, it might explode.
  • Very dangerous so not recommended for self disposal.
  • Lithium is rare metal which can be recycled.
2-5 Counterfeit Battery

The increasing growth of portable handheld devices has spawned a healthy selection of aftermarket battery pack suppliers. Both the 3rd party and end users pay a price when counterfeit battery replacements are chosen. You are requested to contact Canon if any counterfeit.
