883 full battery dies in sec after key is turned not even started. she will start but then looses a full charge in 20 sec????????


Even a modest vehicle battery cannot lose a full charge in 20 seconds. That rate of discharge would seriously overheat the internal connections of the battery and render it useless as well as causing lots of smoke and heating of whatever was causing the dead short.
Clearly the battery does not have a full charge or if it does there is a fault.

The battery clearly needs charging and testing off the car to determine the state of health. I speculate it has a faulty cell.

Laptop works great on AC input, Battery charges and discharges per the indicators but will not power up on DC only. What needs replacing?


If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

I HAVE 2 BATTERIES AND THEY WILL NOT STAY CHARGED. THE CAMERA IS ONLY 2 YEARS OLD. DO I NEED TO REPLACE THE BATTERIES?


This might indeed be the case if you had the batteries for a while, and have recharged them several times. Unfortunately, even rechargeable batteries don't last forever, and need to be replaced. You can actually shorten this life of rechargeable batteries if you don't "discharge", or, "charge" them up correctly when first purchased, strange as that might seem.

Hope this helps. :)

I change my batteries 2 times but still it easily drain.IS the problem the battery, the charger or the unit?


Hello.
The problem of your phone is from the charging port sin you have change your phone battery two times to determine your phone and charger this means that your phone charging port is bad it is the cost of battery drain.
What you need to do is to replace the charging port with a better one from a good phone work shop around or you get the port your self and fix it up.
Thank for using fixya .
Take care.

Battery


Before you change the battery:
  1. Charge the battery fully
  2. Discharge the battery fully
  3. Repeat steps 1 and 2
If the battery does not reset itself and start lasting longer then you do need to replace it.

How do I discharge a battery


Why do you want to discharge. Lithium Ion batteries do not have a memory, though they do require a few charge cycles to reach full capacity. In this case, discharge in camera under normal usage.

Another possibility is if you got a very good deal on the internet for a battery, say 50% off, chances are the date code for this battery, even if it was bubble packaged, had expired. Lithium batteries have about a year shelf life before they begin to fail to completely take a charge. Retailers know this and dump them onto the 'gray' market. Another possibility is if you got a very good deal on a charger for your batteries. Lithium batteries are much more complicated to charge and a cheap charger can hurt them more easily than a cheap charge can hurt a nicad or nimh.
