Advice for getting 3 seconds of 2.5Amp current out of a 9v battery?
Due to the 9V batteries high internal resistance and relatively low mAh, the best solution is to use a high discharge battery such as a 18650. The upside of this is that while the battery is more expensive, you can include a battery management system to charge the batteries, and they have insanely high discharge rates and mAh capacity.
Why do old batteries take the same amount of time to charge
Older lithium batteries actually take longer to charge because oxidation of the plates causes their internal resistance to increase, which increases internal voltage drop and reduces the time that maximum charge current can be applied for without exceeding the maximum charge voltage.. Most lithium chargers are ''CVCC'' (Constant Voltage Constant

Does having batteries in parallel only increase the current
Batteries have "voltage sag" when you pull current from them, this is caused by that resistance. Adding resistors in parallel with each other decreases overall resistance. So two batteries in parallel will experience less voltage sag at a given load. 10 will experience less than that.
batteries
Electrolyte conductivity is strongly affected by ion concentration, so its resistance will increase as the battery is discharged and fewer ions are left in solution (those fewer ions must move faster to create the same current, and thus have more collisions which is
ELI5: Why does the voltage increase with batteries that are
In series, the electricity has to run through one battery into the next battery. This limits the current to the amount that can fit through the battery (which is constrained by the chemistry and geometry of the structure inside the battery). You get twice the voltage because both batteries provide some, but only the current of one battery.
