NOCO GENIUS1 – 1 A Smart Battery Charger for 6 V & 12 V Batteries – Automatic Maintainer – Works for Lead‑Acid & Lithium

Supports both 6 V and 12 V battery systems — ideal for cars, motorcycles, lawn mowers, classic vehicles, deep‑cycle and lithium batteries.

Compatible with multiple chemistries: flooded lead‑acid, AGM, gel, EFB, maintenance‑free, and lithium‑ion (LiFePO₄) batteries.

Features smart multi‑stage charging: includes desulfation/acid‑stratification repair, bulk charge, absorption and float/maintenance mode.

Includes Force Mode to revive deeply discharged batteries (down to 1 V and even 0 V in special conditions).

Integrated thermal sensor adjusts charge profile based on ambient temperature (safe from –20 °C to +40 °C operating range) to avoid under‑ or over‑charging.

Built‑in safety protections: spark‑proof clamps, reverse‑polarity protection, short‑circuit protection, over‑charge protection.

Compact, rugged design (approx. 0.35 kg / 0.77 lb) — uses high‑frequency switch‑mode technology for efficiency and portability.
