Question about Radio Communications
This one [FT60] is fine when running from the DC receptacle. just wont function with the battery pack. I've tested the battery pack output, full 9.6v with fresh batteries, yes I've cleaned all the contacts (radio and battery pack) any ideas???
I just looked at the schematic and the only problem is likely the charging, or external power connection not connecting the battery when the plug is removed. A bit of De-Oxit spray may resolve the problem, or the connector itself may need to be repaired/replaced. This happens a lot with this type of connector.

Battery back needs to be connected to the DVD player when charging. connect the batter pack to player. Run the DC/out from the battery pack to the DC/in in the player. plug the charger into the wall.
if that does not work, you have a bad battery

Hello pjbracht, I just responed to a duplicate of your problem. If they are new, return the battiers and confirm they are "by the book" replacements. If so ask for replacemrnts with a higher mAhr. It is not correct for vibration from a battery pack, lead, NiCad, Ni-MH, period.

Li-Ion battery and NiMh battery have completely different charging requirements! Li-Ion battery has much stricter charging requirement and the regulator is normally design to trickle charge at 0.1 Current rating @ 4.2V and then completely shut down.
WARNING: if you use a Ni-Mh charger on a Li-Ion battery, then it will erupt and even explode and catch fire!
Bottom line is that the rescued Li-ion regulator is not designed for your Ni-Mh pack and you will never get a full charge with it and you will need a completely different regulator board: you are better off putting in a suitably sized Li-Ion battery with inbuilt regulator but with higher current rating if possible.
Hope it helps! Let me know how you go.
