I installed a Renata battery in my ACRO on 15 June. Unit was off for around 48 hours due to trips, etc.. As of this afternoon, I had shot a Steel Challenge and a small IDPA match, about 200 rounds total, with no issues. I have been practicing “power management”, for lack of a better term. Level 7/8 at dusk, level 9 during bright daylight. As of 2000h this evening, unit still goes to “10”.
My belief is that with power management, one can manage the unit successfully over a month. I’ll change the battery this week, and continue on a monthly basis. I do wish the battery life was longer, but I am pleased with the format of two lenses, and have seen no issues with daily carry.
Perhaps the rumor of a modified design will be true, and improvement forthcoming. Time will tell.
