How to buy a Digital Camera Battery
November 15th, 2011 | Author: admin
Perhaps the most difficult problem that most clients face when getting a digicam is that the battery life is typically extraordinarily short. Alkaline batteries are drained within a few minutes by most cameras. The reason for that is that cameras pull a lot of energy quickly from the battery and alkaline batteries are not designed for such fast spurts of power. For those that have electronic cameras that accept AA type batteries I suggest using Nickel Metal Hydride batteries. They work best with digicams, are rechargeable up to 1000 times, and have no problems with a memory effect like Nickel Cadmium batteries do. For everybody else most cameras use Lithium-ion batteries.
Lithium/ion batteries are also chargeable just like Nickel Metal Hydride, but they are more limited on the quantity of times that they can be recharged. Most batteries with high quality cells will hold up to 150 recharges. Lithium Ion batteries also age, the chemistry that permits them to store power starts to break down inside 3 years. So you shouldn't expect your digicam batteries to last longer than about 3 years. So why do almost all cameras use Li-Ion batteries if they're inferior to Nickel Metal Hydride?
Li-ion Batteries are lighter than Nickel Metal Hydride batteries for the energy that they store. That implies that a smaller lighter battery can be used to power the same camera. The second reason is easy economics. Digital Camera firms make a good bit of their money selling accessories for their own cameras. If they can sell a brand name battery for $60 that costs them $6 to make that is a superb ROI.
Just about as quickly as Li-Ion batteries were employed in electronic cameras 3rd party batteries were sold as a generic alternative. The cost of these batteries is much less, but there are 2 issues. The very cheapest of these 3rd party batteries typically use low quality Li-ion cells. This means that they hold less charge and have an especially short lifetime. When it comes to buying 3rd party batteries as an expert I advise purchasing from SterlingTEK. They're in the medium price bracket and the quality is similar to Nikon, Canon, Sony, etc..
Some of the newest Li-ion digital camera batteries also include smart chips. If you have a look for instance at the Canon 7d Battery , which uses a LP-E6 battery n0I8LgRU. You will find the camera uses an onboard chip to measure the quantity of energy that's left in the battery. Some camera makers are now even blocking the utilising of 3rd party batteries by using these chips. That is one more reason to avoid mud inexpensive 3rd party batteries, they frequently don't include the smart chips and won't work with all camera models particularly the latest ones.
