OK, this is wierd.
I changed the Pentagon batteries after the light initially malfunctioned last night. I used a pair of SureFire Batteries which were already loaded and working fine in my SF X200A just seconds before I pulled them out to use them in the X2-HA. The Pentagon light wouldn't work.
This morning I dug out 2 NIW SureFire batteries and slid them into the X2-HA and it still wouldn't work. WTF?
So, I decided to run up to Publix and get a NIW two-pack of Duracell 123's.
Come home, load up the Duracells and now she's working brighter than when I unwrapped her Wed. last week.
Curious, I tried all the suspect batteries in my IT M3 and M6. Here are the results.
M3 & M6 w/used Pentagon batteries...............Negative function
M3 & M6 w/used SureFire batteries................Negative function
M3 & M6 w/NIW SureFire batteries.................Negative function
SureFire X200A w/used SF batteries...............Positive function
SureFire X200A w/used Pentagon batteries.....Negative function
SureFire X200A w/NIW SureFire batteries.......Negative function
X2-HA, M3, M6, SF X200A all worked perfectly with the two NIW Duracell batteries.
Maybe the NIW 2-pack SF batteries are actually old even though I got them 2 months ago.
I paid $11.44 for two Duracell batteries. It's only $3 for two SF batteries.
Maybe the SF's were just a bad batch.
