I dont understand this amp thing on how long will the battery last but ive found this nice 12v battery in ebay and it also comes with a carrying case. Heres the link. http://www.ebay.com/itm/12-Volt-Rec...US_Batteries&hash=item3cc099e0dd#ht_500wt_922. how long will this last till light goes out?
Depends what light you have.. That battery claims to have 7.2 amp hours. Or you could write that as 7200 milli amp hours. If a light draws 500mA then just divide 7200 by 500 and you get your total amount of hours. In this case it would be 14.4 hours. Assuming a full charge and good condition battery.

Amps and volts are much more useful units than watts. For most applications that is.
