Battery Tender 022-0150DLWH 800mA 12V Waterproof Battery Charger

The Battery Tender 022-0150DLWH is a compact, waterproof 12-volt battery charger delivering 800mA of constant current charging power. This charger features the same proven charge characteristics as the Battery Tender Junior but in a completely weatherproof design. The unit is fully encapsulated in thermally conductive, flame-retardant synthetic epoxy resin, protecting internal components from shock, vibration, and moisture—even when fully submerged underwater.

Despite its compact size (no larger than a standard computer mouse), this charger incorporates advanced surface mount technology and an integrated IC chip that constantly monitors battery status. It automatically switches from charging to float maintenance mode once the battery reaches full charge, preventing overcharging and extending battery life. The intelligent charging system makes it ideal for powering sports and recreational vehicles exposed to wet conditions, including motorcycles, ATVs, watercraft, boats, and marine applications.

Key Features:

• 800mA constant current charging with automatic float mode maintenance
• Fully waterproof and submersible design for harsh environments
• Supersmart microprocessor-controlled charging technology
• Spark-proof connection for safe battery hookup
• Short circuit protection and reverse polarity protection
• Lightweight design weighing only 1 pound
• Compatible with all 12V lead-acid, AGM, and gel cell batteries
• 3-year manufacturer warranty

This rugged, affordable charging solution provides reliable battery maintenance for any application where water exposure is a concern, ensuring your batteries stay charged and ready for use year-round.
