Battery Tender Plus 2-Bank Charger | 12V Smart Maintainer 2x1.25A

The Battery Tender Plus 2-Bank Charger is a compact, dual charger that helps you keep 12V batteries ready without the risks of traditional trickle charging. With two independent charging stations, each delivering 12V at 1.25A, you can safely charge and maintain two batteries at once. The design emphasizes reliability for everyday use, from weekend vehicles to motorhomes, boats, and more, with smart monitoring that adapts to battery needs in real time.

Smart, Safe, and Simple

Every station operates with a complete 3-step charging program: Initialization, Bulk Charge, and Float Mode. This sequence helps optimize battery power while preventing overcharging. A solid-state, dual-LED indicator shows the charger’s current stage, and both spark-proof operation and reverse polarity protection add a layer of safety while you connect and forget it.

• Two independent charging stations: 12V each, 1.25A per bank, with temperature compensation for ambient conditions
• Suitable for a range of 12V batteries, including flooded, sealed maintenance-free, AGM, and lead-acid types
• Float/maintenance function keeps batteries at proper storage voltage without stressing the cells

Why This Matters in Daily Use

Whether you park a classic car in the garage, keep a boat on shore power, or maintain a seasonal RV, this charger is designed to be world-ready. The ISM (Infinite Sequential Monitoring) system continuously assesses battery needs hundreds of times per second, delivering the right amount of charge for safe, steady maintenance. The result is less worry about battery sulfation, sluggish starts, or unexpected downtime.

• Reliable maintenance across a variety of climates thanks to temperature compensation
• Compatibility with standard flooded, sealed maintenance-free, AGM, and LiFePO4-compatible setups
• US and international safety standards alignment (UL/CSA/CE/BC) for peace of mind

What You Get and How It Fits Your Space

The two-bank charger ships with a 6 ft AC power cord and a 4.5 ft DC output cord for flexible installation. An integrated design keeps both banks compact and easy to mount in a garage, workshop, or vehicle storage area. A 2-year warranty backs performance so you can trust ongoing maintenance without frequent replacements.
