Are AA battery chargers universal?
Example can I use Duracell battery charger to charge Energizer rechargeable batteries without any issues or vice versa. Can I use Energizer battery charger to charge Rayovac rechargeable batteries. I ask because I have all three brands of AA rechargeable batteries. I just have a Duracell battery charger.

As long as the charger is suited to the chemistry of the cell(s) to be charged,
it will work, but don't use a "rapid" charger for cells that are not specified as such.

What you did not tell us is whether the batteries are single use, throw-away alkaline Lithium or other type, NiCad (Nickel Cadmium), Nickel Metal Hydride (NiMH), Lithium or something else. For the most part
1) Throw-away batteries should not used in a battery charger;
2) NiCad and NiMH batteries can share the same charger;
3) Lithium recharge-ables need s special charger because the battery profile is different.
In any case, the charger should have a manual or a sticker that list what battery chemistry it can recharge.

a parameter ... charging current ...
how much is its charging current?
every battery has a charging current (mA) that depends on its capacity(mAh) ...
the standard charging current equals 1/10 of its capacity for 15 hours charging for a
dead battery ..... for a dead 2500mAh → 250 mA

Only the charger comes with an automatic shut down while battery is fully charged, that can be used to charge all brand AA battery.

a battery recharger will only recharge particular CHEMICAL TYPES of batteries.
The brand of the batter - TYPICALLY - is not important.
(There have been some unique-battery chargers).
if you have a NiCad battery charger
it should charge ANY brand of NiCad battery.
If you have a Lithium battery charger
then it should charge ANY brand of Lithium battery.
There are "universal chargers"
that will charge even alkaline and carbon batteries (i.e. even non-rechargeable batteries).
SO: check which CHEMICAL TYPES of batteries
your recharger is designed to recharge.

Yes, you can use the same charger for all those batteries.
