Camera batteries

Camera batteries are an essential part of our growing demand for personal digital cameras.

Digital cameras have presented everyone with the opportunity to take high-quality pictures in a pocket-sized package. Indeed the popularity of digital cameras has led to a vast growth in the market for rechargeable batteries.

Camera batteries come in various forms and sizes. Smaller cameras can make use of AAA batteries or AA batteries. However, the majority - and certainly larger SLR types - typically come bundled with battery packs.

Battery packs are a collection of interconnected, usually identical batteries that can be recharged using the supplied mains adaptor.

The majority of camera batteries are lithium-ion, and similar technology can be found in:

• Computer batteries.
• Camcorder batteries.
• Mobile phone batteries.
• Cordless phone batteries.

Growing interest in ‘anytime, anywhere’ photography has increased the importance of high-capacity rechargeable batteries - indeed the battery is just as important as the lens or viewfinder.

Maximising your rechargeable battery’s lifespan

Cameras are classed as “high drain”. The power demands of running flash, LCD screens and video functions means that the power offered from alkaline batteries is often consumed in a short period of time.

A more cost-efficient option is to make use of rechargeable batteries. The majority of new digital cameras now come supplied with a rechargeable battery pack - like those used for a cell phone battery.

Many camera users, especially professional photographers, choose to invest in a second rechargeable battery to ensure that their equipment is always available to use.

For less intense users, there are some simple tips that can help to extend battery life.

• Turn off applications such as the flash and LCD screen when not in use.
• Keep the battery charged at around 40% power and store in a cool, dry, clean place when not in use.
• To prevent power discharge, do not allow the battery to fully discharge.
• A new digital camera battery must be fully charged before use. It will typically require four to five complete charges before it will run at its full potential.
• Use a soft cloth to clean the battery’s connection points.

Following these guidelines should bring a noticeable gain in battery power life.

However, rechargeable batteries do suffer from a restricted lifespan of roughly one to three years, and 100 to 1000 charges. Over time, camera batteries tend to lose power and a replacement will be required.
