Without a digital camera battery, you cannot click
The batteries of digital cameras are available in different types. The batteries usually contain L-ion or lithium components. These flat square batteries require charging for continued usage. The batteries have a mAh rating which refers to Milliamp Hour. It is the power that the battery can hold. If the mAh value is higher, it means that the battery can last longer without requiring recharging. For the alkaline or AA batteries, it is best to use a pair that has compatible mAh values. If the values are unequal, your camera could bust, since it will put unnecessary strain on the battery with the higher mAh value.
It is best to use different sets of these camera batteries. This is, in any case, a smart option because you can then have choices when it comes to clicking your photographs. The sets of batteries are charged completely, so that when one pair or set runs out of charge, you have the other set handy. This can be an extremely helpful thing to do, but then you can do something more: you can switch one camera battery to another to conserve power before they are depleted of charge. If the battery is switched, while they have the liquid in them, the process of charging them will require minimal time. You can thus conserve the power too.
The lifespan of the battery is often limited by playback. This refers to the process in which the videos and pictures are viewed immediately after they have been shot. If you spend half an hour taking the photos, and another half hour viewing through them, it can drastically hamper your battery life. With the help of the playback option, you can minimize this time and see the improvement. Switching the camera on or off takes a toll on the batteries. Every start up and shut down consumes loads of energy which mainly comes from your camera batteries. This makes you use the charger often, even when you are not clicking as many pictures.
