The power of a d size battery is usually 13A but it all depends upon the chemistry of battery but these batteries are usually made to support small physical devices.
Do a Google Search for UPS (or uninterruptible Power Supply) which will give battery-backed power for about 10-30 mins depending upon your system's current draw and the size of the battery backed unit.
sealers that activate upon air contact.
Battery run-time on a laptop is difficult to determine. Actual battery running time depends upon the power demands made by the equipment. The use of the screen, the hard drive and other accessories results in an additional drain upon the battery, effectively reducing its running time. The total run-time of the laptop battery is also dependent upon the design of the equipment. Generally, a new Hi-Capacity laptop battery will run 30% to 50% longer than the old laptop battery did when it was new.
Password. This can be setup in the BIOS configuration screen. (F12 or whatever your particular computer calls for upon turning the power on)
no the charging system consists of the battery and the alternator. the battery being the starting point of the system. the battery provides the initial power. the alternator then keeps your battery charged while the motor is running. the starter gets its power from the battery but has no relation to the charging system. the starter has but only one function and that is to power up upon initial start up and turn your motor over to get it running. hope that helps you out a little bit.

From your description it sounds as if the warning light is operating correctly. When the engine is running the battery is being charged and the electrical needs of the vehicle are being fully met by the alternator's output and the battery is not expending stored power. When you turn the engine off the alternator stops running and anything in the vehicle that requires electircal power is suddenly dependent upon the battery to supply it. Thus, the battery begins discharging power, which triggers the warning light indicating that the battery is being discharged.
