9090 batteries not holding charge

maybe its time for a new battery

Depends is it cold weather leaving them for a few days kills the battery duff battery will not hold charge most garages do free battery tests as they want you to buy from them or faulty earth faulty charging unit or you have a wiring short takibg power from battery there could be many reasons but i would go with first three first

Most laptop batteries have a life expectancy of two years or 400 to 450 charge and discharge cycles. After this time, the battery may lose the ability to charge or to hold a charge for substantial periods of time. When this happens, it's likely the battery needs replacement. However, troubleshooting can narrow the problem and ensure you are not wasting money on a battery replacement.

Check Power Adapter Turn the laptop off. Remove any power cords or power sources. Separate the battery from the bottom of the laptop. Slide or press the locking mechanism to unlock the battery. Slide the battery out of the battery compartment. Plug the power adapter into an electrical outlet. Insert the opposite end of the adapter into the charging outlet on the side of a laptop. Power on the laptop. If the laptop does not turn on, the power adapter is not correctly working. If the power adapter is not working, the battery can not charge. Replace the power adapter. If the laptop powers on, the power adapter is properly working. Clean Battery Contacts Turn the computer off. Remove any power cords or sources. Take the battery out of the battery compartment. Dip a cotton swab in isopropyl alcohol. Rub the dampened swab on the battery compartment and battery contacts. Dust and buildup can prevent battery contacts from properly charging. Slide the battery back into the battery compartment. b> Charge and Test Battery Plug the power adapter into the laptop. Charge the battery for six hours. Remove the power adapter. Turn the laptop on. If the laptop turns on and stays on for at least 30 minutes, the battery is holding a charge. If the laptop doesn't turn on or the battery doesn't power the laptop for at least 30 minutes, the battery should be replaced.

Sorry for the difficulties experiencing with the Camera.

Don't know what the expected battery life is for the product. But all rechargeable batteries lose life everytime they are recharged and drained. This is normal. You could send it to the maufacturer and have a/new battery(s)installed into product. Or if you can remove the battery yourself, you may be able to buy replacements from manufacturer or Radioshack or where ever batteries are sold. If product(s) is/are still under warranty, then send to manufacturer for replacement.

this means that your battery has very little remaining power. If you just charged the battery it means your battery is going bad. Replace the battery.

How old is your battery? You may want to think about buying a new one as it may be on it's way out. Even if it is fairly new you might have a lemon of a battery. It happens at times. IF your psp is new and your battery is doing this you should contact sony and see if they can replace your battery for free or a nominal charge.

Hey donoman,
I am going on the assumption that these batteries are not new. Most rechargeable batteries lose their ability to hold a charge after time, and it might be time to invest in new batteries. Another cause of this could be that you are mixing older batteries with newer batteries, and by doing this the length of the charge is dependent on the weakest battery. Things that significantly affect battery life are camera flash, LCD screens, and battery temperature (the lower the temperature the quicker the battery will drain). Another thing to consider is when a rechargeable battery starts to fail they fail quickly, where disposable batteries generally have a longer life and drain at a more constant rate.

Sincerely,
Allan
