Micro T-1 battery last 20 minutes max??

In regards to my Aimpoint Micro T-1, I just bought a variety of CR2032 lithium batteries from Amazon. I have tried, Duracell, Energizer, Panasonic, Toshiba, Phillips and Tenergy and I only get roughly 20 minutes of battery life. I put a new battery in and set the power output mode to 5 and can clearly and visually see the red dot, turn the power off completely. Wait approximately 20 minutes and turn back on and the battery is completely dead. I purchased a dedicated CR2032 battery tester from Pixnor and confirmed that every battery is dead.

Am I missing something? This just started happening within the last 5 days. I thought at first I bought old batteries but this is too consistent. My T-1 is approximately 4 years old and has been used maybe 5 times- maybe 300 rounds. Always turned off when not in use. I put a KAC battery cap on last year and it was not a problem then. Weapon is always stored in gun bag, inside house, never dropped, abused or have any noticeable wear.

How long do the T-1 diode usually last? Is this fixable. Any suggestions?

Thanks

Have you contacted Aimpoint?

This.

Something is wrong with your T1. Contact Aimpoint and they will make it right. They have great CS

I change the batteries in my T-1’s every Feb. 29th whether they need it or not. Something is wrong with yours, it may sound like the proverbial broken record but, contact Aimpoint.

Try it with the Aimpoint battery cap. The kac requires two batteries back to back.

I have an H-1 that has been sitting in my gun safe for 4 years or more with batteries in it and the dot set on the lowest setting. Still works.

My T-1 has had the same battery for over a year now and been left on constantly in the safe and is still going strong. I would definitely contact Aimpoint

I would try it with the original cap and a fresh battery. A buddy of mine recently had some problems on his Aimpoint that were remedied by going back to the original cap.

The A answer is to return to the OEM cap and give it a go.
After that, contact Aimpoint. My one dealing with them over an H1 was very positive.:slight_smile:

If you really want to get into the weeds, loan your KAC cap to a friend with an Aimpoint and see if they can reproduce the results.

I have had a T-1 on my duty rifle and have changed the battery once in seven years. It has never been turned off and stays on setting #8. I changed it at the 5 year mark just because. Let us know what Aimpoint says.

Your first hunch is prob the correct one. Batteries were either old or counterfeit. I made the mistake of buying a dozen coin batteries at a ridiculous price off Amazon once as well, but never again. Pick up a legit 2032 from the hardware store and retest before you start complaining to AP.

Any progress in determining the cause of the battery drain?
