I have often bought several rechargable batteires but they as soon as I recharge i get low battery message. A 590 IS

I would suspect that the battery is no longer good, these must be replaced by Apple contact their websit for instructions on how to do this.

did u try connecting it to your computer like i do mine

are you changing them with top quality alkaline batteries... digital cameras basically eat batteries and you should invest in some rechargable batteries for it.

call customer service 800-701-5327 they might be willing to replace it even after warranty has expired.

Exactly the same. Used to be fine. It has only just started doing this.

I had this problem yesterday. I discharged and recharged several sets of batteries and the set I had the problem with continued to with the one shot problem the other sets workrd fine.

Have you tried recharging the MP3 player? I too have a Sansa Clip which I play in the car so I don't often see the "battery low' message, but when I recharge it the MP3 player works again. I understand it takes longer to recharge from the computer so I bought a recharger I plug into the wall.

rechargible batterys need to be charged before used on anything

The back up battery should be replaced immediately upon seeing the message "Backup Battery Very Low - Your back up battery is very low or missing. Data loss may result from failure to replace the battery very soon. Consult the manufacturer's instructions for directions on replacing or charging the backup battery." Warning: It is important to note that the back up battery in the MobilePro 900 is not rechargeable, thus, to prevent data loss, it is important to change the back up battery immediately when this message is displayed.
