    I got the rechargeable cells and charger from here.

    2 18500's are the recomended size for the 2c Maglite.
    These are a tighter and rattle free fit than the cr123's.
    I would kinda recommend the "protected" versions of the rechargeable batteries that are now available there.
    These are much safer and more goof proof to charge.
    The 2 blue batteries I showed are older unprotected 18500's that have not blown up yet.

    Other 3x cr123 batteried flashlights are are usually too small inside and will need 2 17500's instead.
    In some cases, even 17500's are still too wide.

    If you feel like building something like this... Get the rechargable batteries. LiOn batteries are eaten like candy in Surefires and other lights that take them.

    (1st picture below)
    On the far left, I took about a quarter inch off of the tailspring and reshaped it with 2 sets of pliers.
    This is so that the tailspring doesn't squash the batteries quite so hard.

    In the middle, I got a 5/8ths inside diameter heater hose from an auto parts store.
    I then cut it to 4 inches long and slit it down one side to hold 3 cr123 lithium batteries.
    This whole thing drops right in there perfect into the light's battery tube. :-)

    On the right, I swapped out the 2 cell bulb with a Maglite 6 cell krypton bulb.
    Then put another 6 cell bulb into the spare holder in the tailcap.

    (Optional) On the far upper right is an optional charger with rechargeable lithium ion batteries.

    Below, I reinstalled the 2c's old 2cell bulb into a 2D I had handy and took this picture of the 2 side by side to show the significant improvement.

    I'm getting about 80-90 minutes of runtime out of the cr123's.
    A 90 - 100 minute runtime is what the 2 optional 18500 batteries are giving this light.
    Nice and cheap backup flashlight for under $30.
