The battery cap is an answer in search of a problem. Other than put someone else's logo on the side of your Aimpoint, it serves no real purpose. There is no reason to carry an extra battery on your gun when it will last for 5+ years.

I'll admit, I have 8 Brand x T-1 extra battery caps and I totally agree with the statement above. My oldest H-1 is 6.5 years old and is running on the original battery.
The aftermarket caps can occasionally cause problems. I put one on a 2 MOA H-1 on a BCM LW AR and had intermittent failures when I had only one battery in the KAC cap. I thought the H-1 was the problem but it was the clearance in the battery contacts and cap. It needed two batteries installed to work properly.
I will say the two battery cap is a bit easier to grab and adjust when you have fat fingers or gloves on.
