Battery Help

[Purrkieset]

I'm having some trouble understanding the different types of batteries available.

First, I need...

(5) RCR123A's

and

(2) R18650's

Now...

0. Do I really need AW's? Or can I just buy some Tenergy's?

1. Will the AW RCR123A's fit and work properly in my Olight T20 and my Surefire 6P w/ a Malkoff M60?

2. Will the 2 AW R18650's fit inside a Mag Lite 2D converted to fit two 18650's, a Malkoff P7 drop in installed.

If I decide to go with Tenergy's,

3. Is the TL-100 charger OK with the Tenergy Li-ion 18650 Cylindrical 3.7V 2600mAh Rechargeable Batteries with PCB or should I get the Ultrafire WF-139?

4. And I'm assuming the generic charger included with the Tenergy RCR123A 3.0V 900mAh Rechargeable Li-Ion Protected Batteries works well enough?

Kind of lost, need a lot of questions answered so I can start putting in some orders.

Thanks

Word of advice, do NOT buy Tenergy.

Anyone else? Is Tenergy really that bad?
