When batteries are connected in series, their capacities do not add up directly. Instead, the capacity of the battery pack is determined by the lowest capacity battery in the series. In a scenario with a 15Ah battery combined with a 20Ah battery in series, the overall capacity of the battery pack will be limited to 15Ah, despite the larger capacity of the 20Ah battery.

You should not connect different batteries in parallel. If you do, the battery with the highest voltage will discharge into the other one, until they end up with equal voltages. If the second battery (the lower voltage one) is a rechargeable, then it will be charged by the first one, again until the two have the same voltage.

The thing about larger AH batteries in parallel is you will stress the larger battery more than the smaller one. If the battery is twice the capacity (ie 100ah vs 50ah), then when you pull 75 amps, that means roughly 50 amps will come from the large battery and roughly 25 amps will come from the small one, effectively working the larger battery twice as hard.

Batteries with different capacities would discharge at different rates, so if you had two batteries in parallel of say 1000mAh and 500mAh, there would be a heavy imbalance in the rates of discharge, causing them to be at different state-of-charge percentages.

So, as a general rule of thumb, batteries have a fixed voltage but: big or new batteries tend to have a low internal resistance, so they can deliver a high current small or old batteries tend to have a high internal resistance, so they can't deliver much current This entry was posted in -- By the Physicist, Engineering, Physics.
Now you provide a charge source. Both batteries will start charging but one will take more charge current than the other even at the same state of charge (and voltage). The reason being that the internal resistance of one will be different than the other, based on the state of charge: In the end they'll reach the same state of charge.
When you start to pull current, one battery supplies more current. That will cause that battery to discharge a tiny bit faster, and at some point, that battery's internal voltage will drop to where the other battery will start to carry more of the load. After that point, the cells will self balance.
The people designing other stuff promise to pull less than some maximum current from the battery as long as the voltage applied is in the normal operating range. When these promises are violated, the convenient simple rules of thumb we use ("batteries put out a constant voltage") don't work anymore.
A nearly dead battery still provides 1.5 volts, but has a very high internal resistance so that drawing even a trickle of current zeros out the voltage gain. The voltage across a capacitor on the other hand is always proportional to the charge presently stored in the capacitor (this is the defiition of capacitance ).
