Yourheey 2026 Upgraded 12V/24V Battery Charger & Maintainer — 10 Modes, Color Screen, Auto Shutoff

Overview

The Yourheey 2026 Upgraded 12V/24V Battery Charger & Maintainer is built to perform reliably across garages, marinas, and roadside stops. A rugged aluminum alloy housing houses military grade 13.1 lb pure copper coils, delivering durability and cooler operation with improved heat dissipation for steady charging sessions.

It handles all common lead acid chemistries including AGM, GEL, Flooded, EFB, Calcium, MF and deep cycle batteries. Not compatible with lithium or LiFePO4 cells. The 20A max output provides faster top ups for trucks and RVs while preserving precision for motorcycles, lawn gear, and marine batteries.

Smart pulse repair and health checks

Pulse repair technology uses dual frequency pulses to address sulfation and monitor battery health. The intelligent REPAIR mode can revive batteries that appear stalled and maintain vitality with regular charging, potentially extending usefulness through seasonal storage and active use.

• REPAIR mode analyzes battery health and applies targeted pulses
• Recovers weak cells by dissolving crystalline buildup when feasible
• Supports reconditioned operation down to 3V for stubborn batteries
• Seasonal vehicles stay ready with continuous maintenance charging

Smart voltage detection and safe auto shutoff

Automatic sensing identifies 12V or 24V systems without manual switching. Two charging rates adapt to battery size, with auto off kicking in when fully charged to prevent overcharging and reduce energy waste.

• Auto sensing of system voltage 12V or 24V
• Fast charging for larger batteries above 30Ah and gentle charging for smaller packs
• Automatic shutoff when charge is complete for safety and convenience

All weather performance and winter optimization

Designed for tough environments, this charger delivers a robust charge in cold weather. The winter mode injects additional current to overcome voltage drop at subzero temperatures, helping you regain charge in garages, boat ramps, or roadside situations down to very cold metrics.

Charging optimization and energy efficiency

By combining constant voltage CV and constant current CC modes with energy saving options, it balances safety, speed, and efficiency. Strong mode emphasizes quick top ups when every minute counts, while eco options minimize waste during routine maintenance.

Warranty and support

Backed by a 3 year warranty and 24 7 technical support, yourheey aims to keep you confident about your charger. If you have questions, reach out for guidance on installation, compatibility, or best practices.
