Lead acid battery ?

If a lead acid battery is rated 50Ah, this means that it can provide continuously to a 10A load during 5hrs or full 50A to a load during one hour.But, does that also means that it can provide 100A to a load during 30 minutes?Or 3000A during 1 minute?

Answer:
Since the battery has internal resistance, heat will be generated inside the battery when current flows. At some current level, the rate at which the surrounding air carries heat away will be slower than the rate of heat generation and the battery will overheat. At some higher current level, the heat will not be able to flow quickly enough from the hot spots inside the battery to the outer surface where the surrounding air can carry it away. That can cause the plates to warp and perhaps touch and short the battery internally. The battery could explode if too high a current is drawn even for a very short time. There are probably other limitations on the current vs. energy capability.
No the max current carrying capacity of the battery is determined by the size of the terminals and plates, above which the battery would overheat.
as you pull high amps, battery life will decrease a lot.
and a battery has an internal resistance, that limits max current.

yes,it can provide for both.30mins=0.5hrs,100(0.5)=50...
i min=1/60hrs and 3000(1/60)=50Ah.
