I have some AA rechargeable batteries in a laser host I want to use that are 1.2 volt rechargable. There are 3 joined together for 3.6 volt to 4.2 volt fully charged. How can I test these to get an amperage rating? Are all AA batteries above 2000ma? I need to make sure there above that for a 2A green laser module from O-like...the voltage is right where it needs to be, just not sure of the amps?
