Two automatic modes to monitor battery state‑of‑charge or test the vehicle charging system; four LEDs indicate charge level.
Monitor the charge of stored motorsport lead‑acid and AGM batteries and verify the vehicle charging system with ease. 🔋
Two automatic modes let the unit act as a battery state‑of‑charge monitor (single LED flashing) or as a charging system test (arrow mode). ⚡
Four LEDs cover the full‑to‑empty voltage range used on performance batteries; the fourth very‑bright LED indicates top charge.
In battery mode the LED matching the charge level blinks every 5 seconds to keep long‑term draw extremely low (<0.2mA).
In vehicle charge system mode, the arrow LED activates at charge thresholds to show when the alternator is reaching charge and when it is in the ideal range.
