2002 C240 not starting after charging battery
I own a 2002 C240. I charged the battery and now it cant start.
When I turn the key the ignition sound can be heard however engine does not start. (When battery was dead, there was no such sound, a "click" was heard instead).
I read the manual and it says that it the side windows, sunroof and ESP requires resetting. I cant reset the ESP however as it requires the engine to run.
Is there anything else that i miss?
Thank you in advance.

It may have damaged some of the electronics of the car.

Thank you for the replies.
The battery went flat cos it was left for a lengthy period of time as i went overseas.
In regards to disconnection before charging, I was informed that when the engine is running, the battery is charged at the same time. So i got the impression that disconnecting was not necessary.
Could the electronics be really damaged? And would this be the cause to why the engine could not start?
Thx again.

Purging the bad data
When the factory designed the software for the engine and transmission
mapping, it was obviously based on the hardware parts being completely broken
in. Yet our car's computer has been building up a "learned" database during
breakin, when the parts are wearing in to their "set." Thus, there may be
incorrect relationships between what the engine and transmission are doing
compared with the design. The factory says it takes at least a 1000 miles to
breakin, but I have waited for 2000 miles to pass before purging the bad
data. The time has arrived to reboot the operating system, just like Windows.
It is quite a simple process. Just disconnect the battery for about 30
minutes. 30 minutes is a good amount of time to be sure that whatever can be
purged, will be purged. After reconnecting the battery, and performing the
four "sync" operations in the handbook and resetting the "settings" and time,
everything is back to normal. Drive around for a few miles, and the good data
will have been learned.
My results are fantastic. The transmission shifts are now perfectly torque
managed the way AMG designed them (eliminating the abruptness I had on
1st-2nd at about 3000rpm). The occasional delay in locking up the torque
converter in 2nd and 3rd gear is gone (sounded like slipping the clutch on a
manual transmission). The engine idle is smoother (it sounded a little lumpy
before). The throttle response is sharp (feels like another 5 hp has come
out). I have done this purging, i.e., temporary battery disconnect, on my
last 10 new cars. For some, the results were dramatic (like this C32), and in
others, hardly anything was different. It probably depends on the individual
car. A mechanic told me about this trick back when on-board- diagnostics
(OBDII) started getting complex in the mid 90s.

While what you've posted is accurate,that's not the issue here.His car will not start.

ah right i see what you mean, so back to basics, is there a spark at the plugs?? can you hear the fuel pump cycle when you turn the ignition on "but not atemting to start the engine"?? do the ignition lights come on?? are the earth connections from the battery to the chassis/engine sound?? is there plenty of fuel in
