Won't charge after ipod battery replacement

Question

Hi,
I hope you can help me.
Battery replacements for iPod generation 1 (5 GB) and iPod Photo generation 4(?) (60 GB) did not work:
I bought replacement batteries from OWC (MacSales.com). Below is the invoice data from OWC for theses batteries. Since the swapping didn't work the first time, they sent me new batteries for free, but to no avail.
NWTBIPOD1350MPH
Apple iPod Photo 1350mAh High-Cap Battery
S/N: 5818602, replacement for S/N: 5554860
NWTBIPOD2200M12
Apple iPod 1G/2G 2200mAh High-Cap Battery
S/N: 3761061, replacement for S/N: 3761112
Neither the iPod Photo nor the iPod 1G would work after installing new batteries. The batteries were replaced by OWC, but even a new install with the new replacement batteries did not work. Both iPods worked fine after each installment with the batteries as long as there were some power left in the new batteries. As I recall, that would be about 2 hours. After the first complete charge of the batteries, the iPods seemed to work as expected, but after the second charge they both appeared completely dead. The charging was done with the chargers that came with the iPods. This is very odd, and it is hard to tell what the problem may be. I find it strange that this happens to both the 1. and 4. generation of iPods, as they are quite different, and so are the batteries, and the same thing happened after trying to swap batteries twice on both units.
Do you have any ideas as to what it may be that causes this?
If you know how I can get the iPods to work with the new batteries I would appreciate it. It is no option to buy new iPods. Economy doesn't permit it for the moment.
Best regards from

PS. The iPod 1 (5Gb) was bought at Office Line Mac & Carry (now Humac) in Oslo
        The iPod Photo 4 G (60Gb) was bought at the Apple store. (not the App Store)

Answer 1

- See:      
iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store. I suspect a hardware problem  due to the hotness. If iTunes can't see the iPod then uor only hope if to contact a data recovery company for getting data off the iPod. If you have an iPod backup you can restore another iPod, iPhone or iPad from the backup to get the data that was in the backup
