Not your problem. Resyncing applies to windows (express feature only) and sunroof but not door locks or seats. And it isn't affected by disconnecting the battery unless they were working before hand -- not the other way around.
It sounds like an electrical problem. The car's computer constantly checks for problems. When you disconnect the battery the fault is temporarily erased but will come back eventually when the computer finds it. Maybe a grounding fault -- hard to say. It may be due to some feature you are using intermittently. Bear in mind, also, that locks are pneumatic and the seats are electric so there could be more than one issue involved.

A i had the same problem with my 2001 ml320 i can resynch it and it would work for a little while but then everything goes out again. I had the AAM moduale replaced and it fixed the problem found out about the all activity moduale from this site actually a few years ago when i brought the car.

Search for CAN Bus topics. A failure of one unit (like the rear window motor on mine) breaks the network communications and cuases the other modules to stop responding. You can troubleshoot it yourself by:
1. locate the CAN junction connector under the door sill, in the cable spaghetti below the A-pillar.
2. disconnect one of the 10 items, do a battery disconnect reset, and then drive around for awhile to see if the problem recurs. I would start with the right rear window motor.
3. repeat 2 until successful.
