YHCHKJ 35A 12V/24V Smart Battery Charger for Lithium, LiFePO4, Lead-Acid | 9-Stage Pulse Repair & Trickle Maintainer

Efficient, versatile charging for a range of battery chemistries

Meet the YHCHKJ Battery Charger, engineered to revive depleted cells and maintain power with a compact, garage-friendly footprint. The unit follows a 9-stage charging profile, balancing speed and care to support everyday vehicles and storage batteries alike.

The device handles both 12V and 24V systems and adapts its output to the battery type, helping you top up large batteries in trucks, boats, motorcycles, golf carts, tractors, and RVs without guesswork.

Three-level smart charging for LiFePO4, Lithium, and lead-acid families

The charger offers precise voltage and current settings across 12V (10A, 20A, 35A) and 24V (5A, 10A, 18A). This targeted approach helps deliver optimized charging curves and can be suitable for AGM, Gel, SLA, and marine batteries, reducing the risk of overcharging.

Safety-first design for year-round use

Smart control, temperature compensation for hot or cold climates, and robust protections create a safer charging experience. A cooling mechanism, fireproof materials, and safeguards against overcurrent and short circuits help you charge with confidence, even during storage or off-season periods.

Pulse Repair and maintenance mode

Pulse Repair technology can help reactivate aging lead-acid cells, while the trickle charge phase stabilizes voltage to prevent overcharging. Together, they support ongoing battery health and readiness for future use.

Practical, everyday use with clear guidance

Compact and versatile, the charger fits neatly in a garage, on a boat, or in a travel kit. It is not a jump starter and requires at least 2V to initiate charging, but it provides a reliable maintenance and charging solution for seasonal or routine use.

With YHCHKJ, you gain a thoughtful, feature-rich charger that emphasizes safe operation, battery longevity, and real-world convenience without promising guarantees or shortcuts.
