Camera batteries : what you need to know
Taking a photo often means capturing a moment that will never come again. But without a battery, there's no shutter, no screen, and therefore... no image. This is a detail that is sometimes overlooked when choosing a camera, especially at the beginning.
Between regular batteries, lithium-ion batteries, proprietary models and universal models, it can be difficult to know which one to choose. Which battery should you choose? How long will it last? And above all, how can you prevent it from failing at the wrong moment?
In this article, we'll help you see things more clearly. You'll find out how to identify the battery you need, how long it lasts, how to take care of it, and what you can expect in terms of longevity. Follow the guide.
How to choose the right battery for your camera?
Many photographers, both beginners and experienced, ask themselves this question when buying equipment. With so many different brands, models and formats available, it can be difficult to know where to start. Here's how to make the right choice with ease.
Which battery is right for a camera?
Before buying a battery, it's essential to understand the different types of power sources that can be found in a camera. Depending on the model, requirements vary considerably.
Most modern cameras run on lithium-ion batteries. These are rechargeable, compact and lightweight batteries that can power a camera for several hours. They are often specific to a particular brand or range of cameras. This is the case, for example, with the AgfaPhoto Realishot DC8200, a simple and effective camera that runs on lithium batteries.
Other models, particularly some compact or bridge cameras, still use AA batteries. You can also opt for rechargeable batteries to avoid having to buy batteries regularly. This is a practical solution when travelling without regular access to a power outlet. All you need is a spare pair of batteries in your pocket.
There are also proprietary batteries, designed specifically for a particular model. They are not interchangeable with other models, but they guarantee perfect compatibility with your camera. This is often the preferred option for SLR and hybrid cameras.
How do I know which battery my camera needs?
You don't need to be an expert to identify the right battery. In general, the exact reference is indicated on the original battery supplied with your device. If you no longer have it, you can also consult the user manual or the technical data sheet for the model on the manufacturer's website.
It is important to distinguish between official batteries and compatible batteries. Official batteries are produced by your camera's brand. Compatible batteries are manufactured by other companies but have exactly the same specifications.
At AgfaPhoto, you will find a range of high-quality compatible batteries, designed to offer good performance without compromising on safety. Some camera batteries are specifically developed for AgfaPhoto models and guarantee reliable battery life.
Before purchasing, always check the voltage (V), capacity (mAh) and type of connector. These must match those of your device exactly.
Which battery for your camera?
Batteries are still widely used, especially in compact or disposable cameras. They are easy to replace and ideal for occasional use. But be careful, not all batteries are created equal.
For a camera, it is best to avoid conventional alkaline batteries, which discharge quickly. High-performance rechargeable batteries, such as Ni-MH, are much more efficient. They hold their charge better, especially if you use the flash or zoom.
Let's take the example of a novice user who chooses a small battery-powered compact camera for their holidays. Once there, they realise that they have to change the batteries every two days. With high-quality rechargeable batteries, they could have doubled their battery life while reducing waste.
This is typically the kind of thing that people underestimate when choosing their first camera.

You'll find practical advice on how to better anticipate your needs... including when it comes to power.
Battery life and lifespan
Once you've chosen your battery, you still need to know what to expect in terms of endurance. This can make all the difference, especially when travelling or at an event. A battery that dies in the middle of a photo shoot can quickly turn a wonderful experience into frustration. Here's what you need to know to avoid unpleasant surprises.
How long does a camera battery last?
Battery life varies depending on the type of camera you use. With a compact camera, you can generally expect to take between 150 and 300 photos per charge. Bridge cameras, which often consume more energy, can still take between 200 and 400 photos. As for SLR and hybrid cameras, some models can capture more than 600 photos when using the optical viewfinder.
But these figures depend heavily on your habits. If you leave the screen on all the time, activate the flash or film in Full HD, the battery will run out more quickly. Autofocus and stabilisation can also consume a lot of energy.
Let's imagine a user who goes for a walk with their compact AgfaPhoto. They shoot in automatic mode, with the screen on and a little zoom. They can expect to take around 200 photos before having to recharge, provided they turn off the camera between each series of shots.
In any case, it's better to plan ahead. Having a spare battery or batteries ready to use allows you to stay focused on the photo, not on the charge level.
What is the average life span of a camera battery?
A battery does not last forever. On average, a lithium-ion battery offers between 300 and 500 charge cycles. One cycle corresponds to a complete discharge followed by a recharge. This means that with regular use, you can count on several years of loyal service.
Over time, you may notice that your battery drains faster or takes longer to reach 100%. These are often the first signs of wear. This does not mean that it is unusable, but you should start considering a replacement.
A good habit to get into is to recharge the battery halfway before storing it if you are not going to use your device for several weeks. A battery that is stored completely empty or completely full can lose capacity more quickly.
And to avoid losing everything due to an unexpected battery failure, remember to make regular copies of your photos. If you don't know how to do this, our guide How to back up your photos without the hassle can help you get into good habits.
How much does a camera battery cost?
The price of a battery depends on several factors, including the model, brand and type of power supply. On average, you can expect to pay between £10 and £45.
Official batteries are often the most expensive, but they guarantee full compatibility with your device. High-quality compatible batteries, such as those offered by AgfaPhoto, offer an excellent compromise between performance and affordability. For example, the battery designed for the Realishot DC5200 model offers excellent battery life while remaining within a reasonable price range. What's more, AgfaPhoto batteries are simply priced at £8.33 each. They are affordable enough to buy several spares for a road trip, for example.
Finally, if your device runs on AA batteries, consider investing in good quality rechargeable batteries. In the long run, they are often more economical and environmentally friendly than disposable batteries.
Tips for extending battery life and preserving your battery
A good battery is great. Knowing how to preserve it is even better. These practical tips will help you avoid unpleasant surprises, especially when you're out on assignment or on a weekend trip without a charger handy. With a few simple steps, you can not only increase your battery life, but also extend the life of your battery in the long term.
How can I preserve my camera's battery?
There are several simple ways to limit energy consumption during use. The first is to turn off the screen when you're not using it. On some devices, the screen stays on even between shots. Sometimes, simply adjusting a setting in the menu can save several minutes of battery life.
Burst mode, although useful for capturing the perfect moment, puts a lot of strain on the battery. It is best to use it sparingly, only when the moment warrants it. The same goes for the flash, which consumes a lot of power with each flash. If the ambient light allows it, use natural light or slightly increase the ISO sensitivity.
Another important point: always use the charger recommended by the manufacturer. An unsuitable charger can damage the battery or even cause it to overheat. If in doubt, choose a certified model.
Finally, always remember to carry a spare battery or a set of extra cells. This small gesture can really make a difference, especially when you are far from any power source.
Tips for optimising battery life in the long term
Battery life does not only depend on how often you use it. It is also a question of good habits.
For example, avoid completely draining the battery before recharging it. Contrary to popular belief, lithium-ion batteries prefer partial charges. It is better to recharge at 30% than to wait until it is flat.
You should also pay attention to the temperature. A battery exposed to extreme cold or heat can lose efficiency or even be damaged. Avoid leaving your device in a car in direct sunlight or at the bottom of a rucksack in the middle of winter.
If you are not using your device for a while, remember to store the battery at around 50% charge in a dry place at room temperature. This is a good practice for preserving its capacity over time.
These simple steps will help you keep your battery performing well for longer, without having to invest too often in a replacement model.
