Could you try explain it to me in simple words that >even an engineer might understand? These figures assume that the battery is completely discharged after an hour which is not likely in normal use. 2.2AH means that if drained at 2.2 amps, it will be discharged in 1 hour. Same for the other battery being drained at a 4.4 amp rate. Multiplying those currents by the voltage (ignoring the drop in voltage as complete discharge is approached) Gives the wattages shown. -- Rich Greenberg Sarasota, FL, USA richgr atsign panix.com + 1 941 378 2097 Eastern time.
