What is CR2 battery? If you have no idea on what CR2 battery is, it’s a dry cell type battery widely utilized in cameras. Not only is CR2 used in film and digital cameras, it’s also commonly used in flashlights, photographic gear and a number of portable electronic gadgets.

With dimension of 27 mm (L) × 15.6 mm (D), CR2 lithium battery is required to produce compact gadgets. One of my friends told me that he has done a test to compare the performance of CR2 battery and alkaline battery when taking pictures with his cameras. He said that compared to alkaline batteries, the CR2 batteries are far better in performance.

Energizer CR2 Battery

One of the popular names when it comes to best battery for camera should be Energizer. ‘Long lasting performance’ is what people have in mind about the Energizer batteries. One of their latest batteries is the Energizer CR2 Photo Lithium battery. Designed especially for use in photography devices, watches, calculators and memory backup, the Energizer CR2 battery is a worth buying for those who use lithium-ion batteries to power their digital devices including digital camera.

The Energizer CR 2 battery is a lithium photo battery with a high energy density. The battery provides optimum, long-lasting performance for your digital camera and other digital applications. This CR2 battery is so dependable that you can count on them shot after shot and they deliver long-lasting power to keep up with today’s high-tech, high drains devices like cameras and flash units.

When dealing with extreme temperatures the Energizer CR2 Battery consistently performs well. You can take pictures on snow-covered hill or out in the desert without worry about your power supply. In addition, this  CR 2 battery  is estimated to last for up to 10 years at room temperature.

The Energizer CR2 lithium battery contains a Positive Temperature Coefficient (PTC) safety device that brings the current under control during short circuit conditions.

Let’s take a look at the specifications of the CR2 battery:

• Chemical system: Lithium/Manganese Dioxide (Li/MnO₂)
• Operating and storage temperature: -40 to 60 °C
• Typical capacity: 800 mAh
• Max Discharge: 1000 mA continuous
• Nominal Voltage: 3 volt
• Weight: 11gr

One advantage of lithium batteries including the CR2 battery is that they offer high voltage consistently, as they have a long and flat discharge curve. Moreover, lithium batteries do not suffer from memory effect. Even when the battery is partially charged, users can recharge it whenever they like.

However, it is advisable to store the CR2 batteries with 40% charge for prolonged storage. If you stored them at a very low charge, the Energizer CR2 battery rarely last for several months. At last, remove the battery from your digital camera when you aren’t using it.
