Camera will not power on

Try non-rechargeable batteries, and try testing your rechargeable batteries because they do wear out.

have you tried using other brand of batteries ?
if you use rechargeable batteries, try them fully charged at another device and see if they last that long. if they last more than in the camera, then your camera might have an electric issue

may be batteries you brought are old try with normal ( not rechargeble ) batteries. it would not last long but you can take atleast 30 to 50 photos. if it works it means new batteries are faulty.this type of problem i never saw in camera.use SANYO harmolattice HR-3UQ batteries.

Solution: As digital cameras become more advanced and include more features, the power needed to keep them functioning has also increased. That means that typical alkaline batteries likely won’t do more than power your camera for a few shots before running out of juice. Sometimes, your digital camera may not power on at all if the inserted alkaline batteries aren’t fully charged or powerful enough. Rather than carry along dozens of alkaline batteries for a single photo shoot, you can save money by purchasing rechargeable NiMH (nickel-metal hydride) batteries. Rechargeable batteries can be purchased with a charger that you plug into a wall outlet, and they fully charge in one to five hours depending on the charger and the type of batteries you’re using.

If you’re already using rechargeable batteries but are experiencing short battery life with your digital camera, it’s likely time to replace your rechargeable batteries with new ones. Depending on the number of charging cycles you perform (how many times you discharge and recharge your batteries), rechargeable batteries typically last for two to three years before they no longer hold a full charge. You may also ensure that you’re charging your rechargeable batteries directly before use. As batteries sit unused for extended periods of time, they automatically lose some of their charge.

There are many ways you can conserve battery life while using your digital camera, too. For starters, if your camera has a viewfinder in addition to an LCD, use the viewfinder to frame your shots and turn the LCD off because LCDs draw a lot of power. If you prefer to use the LCD, you can still conserve battery life if you refrain from looking at each picture on the screen after you take it.

Your problem may be due to corrosion on the battery contacts inside the camera which can prevent the full power of the batteries from flowing into the camera. Try this free fix before you do anything else: remove the batteries and wipe the camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sandpaper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and place them back in the camera. This cleaning clears the problem about 90% of the time. If it doesn't work for you, the camera may have a problem that requires professional repair.

BATTERY TIPS

Now a days in LITHIUM BATTERIES are used no memory effect

always charge battery for 16 hours when first use new

never keep ur battery fully discharged for long time when u store ur camera always keep it half charged or fully charged when storing for longer period

it is good to fully discharge once in a month but dont make it ur habit

pls rate me FIXYA for help

i suggest replacing a fresh battery will most likely solve your prob, overtime rechargeable battery can drain easily, try changing with a new battery and see if it does work well, there might be insufficient current, thats why it tends to drop of voltage easily upon using, 
there is a specified lifetime for rechargeable battery, depends on your usage and charging method, theymaybe fully charged but sometimes wont give you enough power to drive 
cheers

Hi,

Possible causes and how to handle them
1. The camera is not on

Turn on the camera. (Operation procedure varies between camera models. Please refer to the camera user guide supplied with your camera.)


2. The rechargeable battery is not fully charged.

Make sure the rechargeable battery is fully charged. If the battery has not been used for an extended period of time, or if it is being used for the first time, it may not be fully charged. In cases like this, fully charge the battery and then discharge it completely in the camera several times to bring the battery back to its normal performance.



The rechargeable battery's capacity diminishes the longer the battery is used. When the battery consumption becomes quicker, the battery life may be at its end. Replace the battery with a new one.


3. The battery terminals are dirty.

When camera does not operate with a brand-new alkaline battery (for cameras that use AA-size batteries) or with a fully charged rechargeable battery, the terminals may be dirty.
Polish the terminals with a dry cloth and make sure the terminals are clean. If the terminals are covered with oil from your skin or similar matter, this may cause poor contact and power may not be fully supplied to the camera.

Also, polish the battery charger terminals with a dry cloth before charging the battery. If the terminals are covered with oil from your skin or similar matter, this may cause poor contact and the battery may not be fully charged.


4. The batteries are not installed correctly (for cameras that use AA-size batteries)

For cameras that use AA-size batteries, multiple batteries are used in one camera. Make sure the direction of each battery matches the direction indicated on the camera. If any of the batteries are improperly inserted, the camera will not operate.


5. The battery cover or CF card (SD card) slot cover is not securely closed

Most cameras have a lock mechanism on the battery cover. The camera will not turn on if the battery cover is not locked or securely closed, or if the CF card (SD card) slot cover is not securely closed. Make sure these covers are securely closed.

The symptoms you describe sound very much like a failing battery. How old is your battery? Rechargeable batteries are only meant to last for a couple years, regardless of use.

If you are using a rechargeable battery, yes you should fully charge it before you use the camera for the first time. Rechargeable batteries are normally supplied without a charge from the factory, but not always. Fully charged batteries may be in storage for a long time before the camera is purchased and unlike modern dry cells, rechargables will not hold a charge for years.

Fully charge your battery, then run it until it has completely exhausted. If you plan to put the camera in storage at some point in the future, always recharge the battery every couple of months or so, to keep it in good condition.

Of course make sure the supplied battery is in fact rechargeable and not a lithium which should not be recharged.
