Welcome to a laptop battery specialist of the Asus Laptop Battery
Just as in any other well-oiled machine, your digital SLR needs its fuel -- and a whole lot of it. Every time a picture is snapped, the camera opens and closes the shutter, the autofocus goes to work, the sensor captures light and color to be processed and saved onto the memory card, and the color LCD screen ices the cake on this energy-eating monster. These are just some of the basic energy-eaters to take into account before getting frustrated with how prematurely your red battery icon begins to flash on your LCD screen. Depending on how much you use the camera, rechargeable batteries typically stay alive for 1-2 weeks.
Since all digital SLRs only ship with one battery such as Asus A42-A3 Battery , Asus A2000 Battery , Asus A42-A2 Battery , Asus A3000 Battery , Asus A6000 Battery , Asus A42-A4 Battery , Asus A4000 Battery , Asus L5800 Battery , Asus A42-L5 Battery , Asus L5000 Battery , you must have a backup plan so you don't miss any golden moments on your vacation. Each camera does not fit every battery and they may use either a rechargeable battery, typically ranging from US$30-$50, or standard AA-size batteries. If the camera you like uses AA-size batteries, look into long-lasting rechargeable AA and AAA batteries that have the highest mAh (milliamps/hr). This is the life of the battery when fully charged.
