Consequently, what is 12v mean?
A 12V battery means that the voltagethatis supplied under nominal load is 12V,that'sit.
Also question is, is higher or lower amps better?
Regarding cordless tools, the more ampsthebattery has, the longer the tool will run. You can have two18Vbatteries, but one might run longer than another because it hasahigher amp rating. One might have an amp ratingof3Ah, while the longer running tool will have 6Ah.
the mA stands for milliamps so for example, yourpowersupply can safely output 6v ats 200mA (or 6v at .2amps) Theamperage is how much current it can give out. For yourproject,whatrever is being powered can safely pull UPTO200mA.
