I would like to power arduino + IComSat GSM with lantern 6V 33ah alkaline battery for a couple of years. Most of the time Arduino will be unplugged thanks to
From time to time, arduino will power on, measure some data, send it to server and die again.
Is it necessary to put any voltage or current regulator / boost between the battery and arduino? GSM can take up to 1A when connected to server.
If so, can you recommend any device / shield to buy?
An alternative to lantern could be 6x D battery = 7.2V, 17ah
