743771 For Lead Acid Batteries with M6 Terminals

The Optimate Smart LED Battery Monitor is an essential tool for Harley-Davidson owners who store their motorcycles for extended periods without constant access to AC power. This unit mounts directly to the battery terminals using standard M6 screws or connects via an existing SAE port, providing a clear visual indication of the current charge state. It features a built-in SAE charge port, allowing for a seamless transition to an Optimate or Zodiac-Mate charger when maintenance is required. Compatible with both lead-acid and lithium batteries, this monitor helps prevent deep discharge cycles that can permanently damage expensive power cells. Sold each, it is a compact solution for proactive battery management.
