Duration: 6:08

This guide details the installation of the Primary Arms AutoLive battery cap, designed to extend LPVO battery life by automatically shutting off illumination after a period of inactivity and reactivating upon motion. The process involves replacing the original battery cap with the AutoLive unit, which then accepts the original cap on top. The speaker notes compatibility is currently limited to Primary Arms SLX Gen 4 optics.

Quick Summary

The Primary Arms AutoLive battery cap extends LPVO battery life by automatically shutting off illumination after about two minutes of inactivity and reactivating it upon detecting motion. This conserves power from the standard CR2032 battery, which typically lasts 100-150 hours at max brightness.

Frequently Asked Questions

What is the Primary Arms AutoLive battery cap and what does it do?

The Primary Arms AutoLive battery cap is an accessory designed to extend the battery life of LPVOs. It automatically shuts off the reticle illumination after a period of inactivity and reactivates it when motion is detected, conserving battery power.

How does the AutoLive battery cap extend LPVO battery life?

It conserves power by automatically disabling the reticle illumination when the optic is stationary for approximately two minutes. Once motion is detected, the illumination immediately reactivates, ensuring you don't miss a target.

What is the typical battery life of an LPVO without an AutoLive cap?

Standard LPVOs using CR2032 batteries typically offer a battery life of around 100 to 150 hours at maximum brightness. The AutoLive cap aims to significantly increase this duration by preventing unnecessary power drain.

Which LPVOs are compatible with the Primary Arms AutoLive battery cap?

Currently, the AutoLive cap is confirmed to be compatible with the Primary Arms SLX Gen 4 LPVO. Testing indicated it does not fit EOTech Voodoo, Vortex PST/Razor, or Nightforce NX8 models due to design differences in their battery caps.
