Dies even with partial battery life

When the battery and the backup battery are gone, the picture frame may take 15 minutes to even show sign of life. If after more than 20 minutes without life, then you will probably have to change the backup bettery - probably a 3 volt-button bettery.

Maybe the life of the battery is almost exhausted. If the battery is charged everytime the laptop is used it will gradually decay in life and energy storage. They are best emptied and then recharged at least once a month. That will help to keep the life of the battery extended as long as possible.

It is probably your alternator. I would have it tested before I do anything else to your vehicle.

The battery has lasted at least 8 years. It has reached its end of life. There is no battery that lasts forever.

How old is the phone? These kinds of batteries need to be handled with care. Meaning, for the battery life to be high, you must fully charge phone, then use the phone till the battery is dead, then fully charge again. Do not charge if there is still juice in the battery and do not take off charger after only partially charging the phone. This will help maintain the life of the battery.

Will the old battery (that you are replacing) charge up at all? If the old battery charges but the new battery will not, then it's likely a bad replacement battery.

To rule out the possibility of a corrupted battery meter inside of windows, you may wish to leave the laptop on battery power only, until it dies. A 5% charge will usually only grant you about 20 minutes of laptop life maximum. Since you left it charging all night, you should get a few hours of life before it dies. If you get a few hours of life, the battery meter software is corrupted.

Most likely though, the replacement battery is bad.

How long is the charge lasting? If you're only getting half of the battery life you use to get, then the unit needs to be repaired. I can do more research into your model, but normally there isn't a way to change the battery charge display. Please let me know if you're still getting full battery life even though the display is only showing half.

I'll use the information you provide to assist you further. I look forward to hearing from you.

Change the battery. It is a 9v battery behind the small door on the back of the display panel.

i know i have to charge my sansa for at least 7-8 hours before the battery will show it is full. about your other problem, i believe there is an option under the settings menu to automatically shut your sansa off. If not then you can turn off the backlight and that will save alot of battery life.

I read somewhere that even with a functional lyra, when it displays "battery full", you should keep charging for another hour. This is said to extend battery life and give you an extra 2-3 hours of power. Either this is perfectly normal, or it indicates that the battery reading tends to be inaccurate. In any case, try leaving it charging even after it gives you the message. Another thing to consider is, how long has it been in the box? I'm not sure about lithiums, but most rechargeables I know live longer when used. Live it alone for too long and you shorten it's life. Could be good to get a second opinion on this battery thing though. If there's a warranty, don't let it waste. Good luck
