Ok Czero,lets end this discussion.But an apollo believer would never be treated like that on this forum.
Hey,lets talk about batteries.Energy is an endless problem until nowadays....Czero,how can you convince me that back in 1969,2 people from the moon surface could send live tv signals carrying that kind of batteries ??? Nowadays,if you go to a soccer stadium ,you will see out of the stadium buses called "motorlinks",that carry huge energy generators and very heavy cables only to send 90 minutes of tv signal to your home.Also,back in 1969 , the videos signals were not compressed..They were transmitted at its very "heavy" original form..So,how could it be possible to have a live tv transmission from the moon???

I don't know hpw I can convince you of anything since you have shown a tendency towards ignoring or misinterpreting the information given to you and making assumptions based upon that lack of understanding.
That said, here are the facts I have been able to find:
The batteries carried on the LM were six 400 Ah (ampere-hour) silver-zinc batteries (later upgraded to 415 Ah batteries for the 3 J missions), 2 in the ascent stage, 4 in the descent stage, which provided power for all LM systems during launch and after separation from the CSM in Lunar orbit prior to landing. These batteries provided between 24 and 32 volts DC and, through a pair of inverters, 115 volts AC power. The whole system was rated as providing 50 KWh (kilowatt hours) of power.
The video camera on Apollo 11 drew 6.5 watts of DC power, and as of yet, I have not found figures showing how much power the S-band system consumed (although I did find information showing that it transmitted at approximately 18 watts, but it did not specify if that was for just the video portion, or for the entire Unified S-Band subsystem). Perhaps someone else has more detailed figures than I have been able to find.
The tv system was not the same system as "standard" tv of the time. It transmitted 320 lines of resolution at 10 frames per second (compared to 525 lines at 30 frames per second for standard tv) operating on a bandwidth of approximately 500 Khz compared to 4.5 Mhz for standard tv. So while the signal might not have been compressed, the signal did not carry as much information as a standard tv signal, however it was sufficient to send viewable tv pictures from the lunar surface.

EDITED to add Parkes link and this last sentence...
There is undoubtedly more information in those sources than I have listed here. This might be a good opportunity for you to have a look through them and find the answers for yourself if mine do not sufficiently answer your questions.
