Xantrex TRUEcharge™3 20A 3 Bank Battery Charger - 24V

TRUEcharge3 20A 3-Bank Battery Charger - 24V delivers a compact, high-performance charging solution for multi-battery systems in RVs, boats, and commercial applications. Designed to fit tight spaces, it combines low electrical interference, a power factor–corrected multistage charging algorithm, and global compatibility to keep your batteries healthy and ready to go.

Key features

• Ultra-compact, drip-proof design for flexible mounting in multiple orientations
• Microprocessor-controlled multistage charging with two- and three-stage settings
• Three-bank, 20A total charging for 24V systems
• Battery compatibility: Gel, Flooded, AGM, and LiFePO4 (lithium-ion) support
• Parallel stacking capability with an optional remote panel
• Ability to charge batteries that are deeply discharged down to extremely low voltage
• Quiet mode option for reduced noise
• Built-in surge and spike protection on the AC input
• Power Factor Corrected (PFC) charging for efficient use of shore power
• Easy-to-read display with optional remote panel for convenient monitoring

Three-stage charging for optimum care

TRUEcharge3 uses a three-stage charging profile to maximize battery life and performance while minimizing wear. Bulk stage rapidly replaces 70–80% of the battery’s charge, Absorption stage carefully replenishes the remaining 20–30% at a safe rate, and Float stage keeps voltage stable to prevent damage and sustain a full charge over time.

Global compatibility and reliability

• Universal AC input: 90–265 VAC, 47–63 Hz for worldwide use (travel-ready and tolerant of variable power)
• Nominal output and settings for 24V systems, including charging and float voltages tuned for diverse battery types
• Battery types supported: Gel, Flooded, AGM, and LiFePO4
• Built-in protection against surges, spikes, reverse polarity, over-temperature, DC over-voltage, and circuit breaker triggering
• Drip-proof construction and wide operating temperature range (0–60°C / 32–140°F)
• Minimum recommended battery bank size: 40 Ah
• Dimensions: 70 x 170 x 250 mm (2.8 x 6.7 x 9.8 inches); Weight: 2.2 kg (4.8 lb)
• Regulatory approvals: CSA, UL, IEC/EN IP32, FCC Part 15

With its compact footprint, sophisticated charging algorithm, and broad battery compatibility, the TRUEcharge3 20A 3-Bank Charger is the trusted choice for keeping your 24V electrical systems ready—whether on the road, on the water, or at the job site.
