Question 2

What is the difference between the red Surefire 123As and the brown ones?  They seem identical, but the brown are cheaper.

Accepted Answer

Surefire red, Surefire brown, streamlight, Panasonic are ALL made in the same Panasonic factory in the US, and of hte same materials with some very very minor tweaks. For example a streamlight will run marginally longer (4%) than surefire at 10 ma very low load, 500 ma low load, and 2 amp maximum load. Surefire will run 3% longer at 1 amp mid/high load. These are trivial. Surefire brown are completely identical to reds BUT probably RISKY here on amazon because it is not amazon selling, but third party sellers, who may have knockoffs,  quality control failure dumps, or old stock. Get streamlight or surefire "sold by" and shipped by amazon, or "sold by" streamlight or surefire which are made by Panasonic in their US factory, or alternately US made panasonic.

Question 3

What are the use by dates on the batteries that are shipping out now (9/2/2014)?

Accepted Answer

I have purchased this item twice.  This was my experience.  I ordered a box in 2020, and the batteries had a 2023 expiration dates, which I noticed too late.  But they worked just fine.  I ordered another box in Feb 2023 and they came with 2031 expiration dates.  All good as far as I am concerned.

Question 4

what  does 1400mAh mean?

Accepted Answer

It's the energy storage capability of the battery. The bigger the number means its able to run a given load for a greater length of time.   Bigger is better.
