The camera battery has evolved and it’s no longer as easy as collecting a pack of AAX from a drugstore. Many cameras use very specific batteries that are only available in camera or computer stores.
The battery is the power source of your digital camera and it is necessary to use the right battery for your camera to work properly. Remember, without a good battery, you can’t take a picture!
Ownership vs. common conventional batteries
Most cameras now require a certain style of battery for a particular camera. Battery style varies by both manufacturer and camera model. It is very important to purchase specially made batteries for your camera model!
Do a search for ‘Nikon Battery’ or ‘Canon Battery’ and you will find different types of batteries in that particular manufacturer. Some for point and shoot cameras and others for DSLR cameras .
The nice thing is that most (not !!) one manufacturer’s DSLR cameras use the same type of battery. This is convenient when upgrading because you (again, in most cases) use the same battery in your new camera as you did in the old camera.
On the other hand, there are a few cameras that run using common battery sizes such as AAA or AA. It is often found in point and shoot cameras.
Some DSLR cameras can be fitted with a vertical inlet accessory that holds two batteries owned by the brand and it can fit the normal battery size. Check your camera body accessories list to see if this is possible.
For cameras that use AA or AAA batteries, disposables should only be used in an emergency if a charger is available. They are very expensive to use every day.
Try carrying disposable lithium AAs for emergencies They are more expensive, but they hold three times the charge and weigh about half as much as standard alkaline AA batteries.
Conventional Rechargeable AA and AAAs (NiCd and NiMH)
Nickel metal hydride (NiMH) batteries are more efficient than older nickel cadmium (NiCd) batteries.
NiMH batteries are twice as powerful, and they have no “memory effect”, which is effective if you recharge a NiCd battery before dinner. The memory effect basically reduces the maximum capacity of the future charge and the memory effect gets worse when repeated.
Rechargeable Lithium-Ion (Li-Ion)
This is the most commonly used style of battery in digital cameras, especially DSLRs. They are lighter, more powerful, and more compact than NiMH batteries, but they cost more.
Li-ion batteries come in a brand-specific format, although some cameras accept disposable lithium batteries (such as CR2s) via an adapter.
Brand name vs. generic battery
Today’s camera manufacturers are also in the battery business. They originate the battery they own in their name so customers can (hopefully) believe they can get a battery. Both Canon and Nikon make batteries for every camera they sell and many other camera manufacturers do as well.
In most cases, generic brand digital cameras do not exist in the market. They are brand name batteries have the exact size and shape and often have the same output of power. They are cheap enough.
While not all generic batteries are bad, one should be careful when buying. Read the review!
The problem may not be immediately apparent with generic batteries, but it may appear in the future. One of the most common problems is the ability of a battery to hold a good charge for a year or two. Granted, it’s not uncommon for any rechargeable battery to weaken, but it often seems that generics weaken faster than brand names.
The point is you should do research. Consider that the money saved in a generic battery today is a potential problem and the cost of a faster replacement may be what is needed.
