charge will be different. Indeed, if all 3 cells are discharged by 100 mAh, but cell 3 has different total capacity (eg: 2000 mAh instead of 2200 mAh), the resulting chemical states of charge will be 95.4 and 95%. This in turn will also cause different OCVs. As can be seen, 200 mAh difference in QMAX causes only 0.4% difference in SOC. Because

Cells/batteries in parallel with different capacity
A 10 Ah battery will deliver only 1/10 th of what a 100 Ah battery will to decay in voltage the same amount. Therefore it delivers what it can as it discharges. The 100 Ah battery delivers approximately 10 times as much to drop it''s voltage the same amount. Make sense ?
Different Capacity Batteries in Parallel
My question is this: What happens if two batteries of different capacities, but same voltage, are placed in parallel? For example, if I put a 2 Ah 1.5v AA battery in parallel with a 20 Ah 1.5v D battery. I think that the larger battery would simply supply more current than the smaller one, so that they both lose voltage at the same rate.

At What Health Percentage Should I Replace My iPhone Battery?
Replace the battery when the battery life bothers you enough to convince you it''s necessary to spend the money on a new battery. An 80 percent battery health level should still be enough to get you through the day for most users. However, at 40 or 50 percent of battery health, things start degrading really rapidly.
Powerbank Capacity Explained: A Quick Guide

Can I Use a Different Battery in My Car? | Home Battery Bank
You can use a different battery in your car as long as it fits securely in the battery box, has the same voltage, and meets or exceeds the manufacturer''s recommended cold-cranking amps (CCA). However, using the manufacturer''s recommended Battery Group Size is the easiest and safest replacement choice.
What are the issues with mixing LiFeP04 batteries of different ...
There are two different capacity issues. ... current then the larger capacity pack will exceed its current rating as it tries to support the load and the weaker battery. If that happens the larger capacity pack will trip and will go off line. I suspect this will cascade to the smaller capacity pack.
Car Battery Amps Explained: The Ultimate Guide
A higher capacity battery can provide more power for a longer period of time. It''s important to note that a battery''s capacity is different from its amps rating. While a higher amps rating means the battery can provide more power at once, a higher capacity battery can provide that power for a longer period of time before needing to be ...
Can I connect batteries of different ampere hours in series?
Putting different capacity batteries is series will lead to disaster because the lower capacity battery will charge up faster and become grossly overcharged, causing it to vent and release gasses that cannot be replaced - and perhaps even explode! Batteries lose performance and may go out of balance as they age.
What would happen if batteries are connected in …
We need to connect batteries in parallel when a single battery cannot do the job. Parallel combination of battery increases output energy. In short, If batteries are connected in parallel, the total output …
battery charging
When charging, the lower-capacity cell will reach its maximum voltage (say, 4.2 V) first, but the pack as a whole will not have reached its maximum voltage (8.4 V) yet, so constant-current charging will continue, and …

You can probably see where this is going–the battery with lower capacity degrades faster, lowering its capacity, which accelerates the process. ... Ok, now we''re talking about something a little different. In ...
What happens if I put a higher amp battery in my car?
The capacity of a battery (ah) is the energy that the battery can provide. The more capacity a battery has, the more energy we can get from it ... What would happen, therefore, if we could connect a 24V battery or 2 12V batteries in series? After all that has been seen, the answer is simple: if we double the voltage, the current intensity would ...
Can I use batteries of higher amperage?
Further, the product of the battery''s voltage and the electric charge rating is the amount of energy the fully charged battery can (ideally) supply. In short, using batteries with extra energy capacity will not harm your device, but would, instead, power the device for a longer time (all other considerations unchanged).

Battery Capacity
The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery. The unit of Ah is commonly used when working with battery systems as the battery voltage will vary throughout the charging or discharging cycle. The Wh ...
Different batteries connected in parallel
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.
Power Capacity and Power Capability | All About Batteries
The way the power capability is measured is in C''s.A C is the Amp-hour capacity divided by 1 hour.

Connecting batteries in parallel – BatteryGuy Knowledge Base
But what happens if you wire batteries of different voltages and amp hour capacities together in parallel? ... as you increase battery capacity and the load does not change, you actually get more usable AH from the same watts, because the battery chemistry has more time to react, instead of a more rapid discharge that reduces both …
Batteries in series vs parallel: what are the differences?
It is important to note that connecting batteries in series also increases the overall capacity of the battery bank in amp-hours. However, the internal resistance of the batteries can also increase, which can result in a lower maximum discharge rate and reduced efficiency of the battery bank. What happens if batteries are not properly …
