High-drain devices like digital cameras need batteries with a high current output, while low-drain devices like remote controls can use standard alkaline batteries. Types of AA Batteries Alkaline Batteries: Ideal for everyday use in low to moderate-drain devices due to their balance of cost and performance.
batteries
The output current (and for that matter, the voltage if you consider a battery with internal resistance) are determined by the combination of the source and the load, not by one or the other alone. If you use load line analysis, then you can find the voltage and current from the intersection of the battery''s IV characteristic and the load …

Batteries are classified into primary and secondary forms: • Primary batteries are designed to be used until exhausted of energy then discarded. Their chemical reactions are generally not reversible, so they cannot be recharged. When the supply of reactants in the battery is exhausted, the battery stops producing current and is useless.

The efficiency of a battery, as with anything, is output/input × 100%. A lead–acid battery at first had an efficiency of about 75%, but thankfully has improved with efficiencies to around 95% with some technologies.
What is the maximum current which can pass in a Li_ion battery?
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C. ...
