At DMG Motorsports, we present the Battery Tender Charge N Start — the ultimate 2-in-1 battery charger and jump starter that ensures you'll never be stranded again. Available in two powerful variants (4 Amp charger with 1200A jump starting, and 1 Amp charger with 1000A jump starting), the Charge N Start replaces two separate devices with a single compact, wall-powered unit. Whether you're maintaining a motorcycle through the off-season or need emergency cranking power for a full-size truck, the Charge N Start has you covered — preventing dead batteries before they happen and rescuing you when prevention wasn't enough.
Features:
- Two Powerful Variants: Choose the 4 Amp charger with 1200 peak amp jump starting (CNS 4120) — ideal for full-size cars, trucks, SUVs, RVs, and boats — or the 1 Amp charger with 1000 peak amp jump starting (CNS 1100), perfectly sized for motorcycles, ATVs, UTVs, scooters, personal watercraft, and compact vehicles.
- ISM Smart Charging Technology: Powered by Battery Tender's exclusive Infinite Sequential Monitoring™ (ISM) algorithm, the charger automatically moves through four stages — initialization, bulk charge, absorption, and float maintenance — adjusting output in real time to prevent overcharging and sulfation for longer battery life.
- Lithium Jump Starting Power: The internal lithium pack delivers up to 1200 peak amps (4 Amp variant) for gas engines up to 6.0L and diesel engines up to 4.0L, or up to 1000 peak amps (1 Amp variant) for gas engines up to 5.0L and diesel engines up to 3.0L — no jumper cables or second vehicle needed.
- Auto-Switching Dual Maintenance: Advanced charging technology automatically switches between maintaining your vehicle's battery and the internal jump starter, ensuring both power sources are always fully charged and ready for use.
- Wide Battery Compatibility: Supports all 12V battery chemistries — standard flooded lead-acid, AGM, GEL cell, sealed maintenance-free, and Lithium (LiFePO4) — with a manual chemistry selector for the correct ISM charging profile.
- Comprehensive Safety Protection: Built-in spark-proof connections, reverse polarity protection, temperature compensation, and SafeGuard circuitry that prevents dangerous backfeeding from the vehicle battery to the jump starter, protecting sensitive vehicle electronics.
- LED Status Indicators & Emergency Light: Easy-to-read LED lights display real-time charging status and battery health, plus a built-in LED emergency light provides critical visibility for nighttime use.
- Heavy-Duty Dedicated Clamp Sets: Separate, dedicated clamp sets for ISM maintenance charging and for jump starting — with copper-plated jaws for strong, reliable connectivity — each engineered specifically for its function.
- Compact & Portable Design: Lightweight lithium-based construction makes the Charge N Start easy to store in your garage, vehicle, or on the trail, and includes a zippered carrying case for protection on the go.
- Broad Vehicle Compatibility: Designed for cars, trucks, SUVs, motorcycles, ATVs, UTVs, side-by-sides, boats, RVs, scooters, lawnmowers, and personal watercraft with 12V battery systems.
