If you use batteries to power a digital camera or an important work tool then the last thing you need is for them to run out just when you most need them. Apart from making sure that you always have a spare set with you on important occasions, there are also a few tips which you could follow in order to extend the battery’s life.

When using rechargeable batteries it is important not to over charge them or charge them when it is not necessary. Even rechargeable batteries don’t last forever and they lose a little bit of their effectiveness every time they are recharged. The key is to recharge them only when it is necessary as this means that they will last longer. This is the opposite from mobile phone batteries, which work best when recharged frequently and when the battery is still half full. At this point it is worth pointing out that recharging non rechargeable units does not work, and will simply cause the battery to overheat and possibly split open.

Non rechargeable batteries can have their life slightly extended by storing them in cool conditions. Most power units discharge their energy quicker in hotter conditions, so keeping them cool makes them last a little longer. Most batteries come with the manufacturers warning to keep them out of direct sunlight. The need to avoid them getting wet may seem obvious but it is nonetheless an important precaution which needs to be taken.

Digital camera users have the choice of a few tips which can help them prolong the life of their batteries. The LCD display is one of the functions which most drain the battery’s power supply so if you have the option of switching this off and using the viewfinder you should do it whenever possible. Looking at previously taken photos on the camera uses up a lot of energy and the image is not as big as it is on your computer or television anyway, so it makes sense to hold off until you get home.

Other elements of a digital camera which consume a high amount of energy are the parts which move in order to help the camera focus. If you can set the camera to continuous or single focus then you will use less power. Also pressing the shutter button half way down without taking a photo uses up a lot of power and should be avoided.

Buying a long lasting battery like a Duracell or Procell is still the best option for having a power unit which will go on for a long time, but hopefully these tips will help you also help you get the most out of your batteries.
