I have a gsmGSM module needthat needs 9v, and 1 amp current to start transmission,transmission; it works with 12v 1.0 amp dc adapter, but when iI use a 9v dc battery whoswith no indicated current rating is not mentioned on the battery it starts but turns off as soon as i triedI try to make a call, can i. Can I use a mahmAh rating 9v battery, so that the gsmGSM module takes current as its needit needs? ifIf not, what can iI use to take 1 amp current from the dcDC battery? isIs there a way? i'mI'm not a electronics engineer i'm, I'm a software guy who doesn't know about electronics. i'mI'm working with bus tracking project for my college, but unfortunately iI couldn't find help for electronics thingside.

I came across batteries with mAh rating, which says mA amount of current can be supplied for an hour; if we pull more power more discharge for less time. Some batteries are rated with voltage and output current; does that mean its current output is fixed?
For some batteries its output current rating is not mentioned but mAh rating and voltage is specified; does that mean current can be discharged according to the resistance in circuit?

variable current rating vs fixed current rating from dc battery, does both of them exist or only one
