I've seen a few posts talking about Gladius draining the batteries even when off. I have the same problem. Occasionally, it drains off the battery within just a few days after using it for total of 5 min. It would do that when it's in locked position too. This is becoming very annoying- I have never gotten to the point when the Gladius starts flashing showing that the batteries are low. Completely unpredictably, one days it works fine, the next day the batteries are simply dead. I sent it to Night-ops for repair. Can you guys, Gladius owners, confirm the same problem and if you've noticed any pattern when this happens? Should it be kept far from any magnetic fields or who knows what?
