If you use alkaline batteries instead of lithium then the batteries will work the same as the lithium batteries but they only transfer the ions in one direction and as the ions move from the anode to the cathode the batteries will lose their voltage as it drains and then the system cannot be recharged.
Lithium ion is better than NiMH AA batteries as Lithium ion AA batteries last for up to 1,000 cycles while the NiMH AA batteries last only 500 cycles.
There are different strengths of AA batteries and especially rechargeable AA batteries.
AA batteries' nominal voltage depends on the exact battery chemistry and the presence of a DC-to-DC converter and ranges from 1.2V to 3.7V.
A typical AA battery has 1.5V and is based on the voltage of Zinc-Carbon chemistry, which is often labeled as "Heavy Duty" '
Rechargeable batteries in the AA size are available in multiple chemistries: nickel–cadmium (NiCd) with a capacity of roughly 600–1,000 mAh, nickel–metal hydride (NiMH) in various capacities of 600–2,750 mAh and lithium-ion.
Batteries do have a use by date and after that the batteries start to lose their charge and eventually can go completely dead.
Unused AA batteries do eventually go bad and all batteries including the AA batteries have an expiration date.
The AA battery may still work after the expiration date but it will not have as much charge and will not last as long as a new battery.
Most AA batteries as well as AAA and C and D cell batteries will last up to 10 years unused and 9 V batteries last up to 5 years unused.
A battery is a chemical product which produces electricity by chemical reactions at its inside.
When the battery has passed the recommended usage period, the components that make up the battery will deteriorate, leading to performance degradation.
That is why there is an expiry date on the battery.
This loss of capacity (aging) in batteries is irreversible.
As the battery loses capacity, the length of time it will power the product (run time) decreases.
Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage.
Routinely check the battery's charge status.
AA batteries start off with 1.5 volts of energy, but the voltage goes down as the batteries are used up.
Once the batteries dip below 1.35 volts, they appear to be dead, even though they still have a lot of juice left.
The best way to store batteries is to do the following.
Keep them in their original packaging. Did you just buy a new pack of batteries and would you like to unbox them immediately?
Separate old and new batteries.
Store them at room temperature or below.
Keep them away from metal objects.
Be sure to control the humidity.
