Battery Tender 5W Solar Panel 12V Battery Charger — Windshield Mountable, IP67 Weatherproof, Built-in Charge Controller

The Battery Tender 5 Watt Solar Panel is a compact, windshield-mountable 12V battery charger with a built-in charge controller that maintains vehicle and deep-cycle batteries without overcharging.

Designed for motorcycles, cars, SUVs, campers and other stored vehicles, this small solar module uses sunlight to keep 12V batteries topped off. It combines a weatherproof panel with a smart charging circuit so batteries receive full charging current when available and automatically switch to float maintenance when voltage is reached. The unit includes mounting hardware and multiple output cables, making it ready to install on glass or use with clamps for long-term storage.

How does the Battery Tender 5W solar panel protect my battery during storage?

The panel's integrated charge controller monitors battery voltage and stops bulk charging once the battery reaches the correct level, then holds the battery at float to prevent overcharge. Built-in protections guard against reverse current at night and prevent sparks during connection.

• Automatic transition from full current to float maintenance
• Spark-proof and reverse charging protection
• Compatible with lithium (LiFePO4), lead-acid, AGM and gel batteries
• IP67-rated sealing against dust and temporary water immersion

Can I mount this panel on my vehicle’s windshield and still use it easily?

Yes — the kit includes four suction cups designed to attach to glass and an 8 ft output cord so you can reach typical cigarette outlet locations. For alternative setups, the alligator clip / ring terminal cable lets you connect directly to battery posts or accessory points.

• Four suction cups for secure windshield mounting
• 8-foot cable to reach dashboard or outlet sockets
• Alligator clip and ring terminal combo cable for direct battery hookup
• Lightweight and compact for simple installation and removal

What weather conditions and environments can the panel tolerate?

The panel is built to IP67 standards, meaning it resists dust ingress and can withstand temporary immersion in water. That makes it suitable for outdoor storage areas, uncovered driveways, sheds, and camper exteriors where it will encounter rain, spray, or dust.

• IP67-rating for dust resistance and temporary water immersion
• Durable construction for outdoor exposure and seasonal storage
• Sealed electronics help prolong service life in variable climates
• Five-year manufacturer limited warranty plus lifetime support

How much charging performance should I expect from a 5 watt panel?

With 5 watts of power, this panel provides a trickle charge sufficient to counteract battery self-discharge and small parasitic drains over time. It’s optimized for maintenance rather than rapid recharge — ideal for keeping batteries healthy between uses rather than replacing a depleted battery quickly.

• Designed for maintenance and float charging, not fast recharging
• Delivers steady current in sunny conditions to maintain voltage
• Best used for seasonal vehicles, motorcycles, ATVs, and stored cars
• Works with multiple battery chemistries when connected properly

Who is this for? The Battery Tender 5 Watt Solar Panel is aimed at vehicle owners who store motorcycles, cars, campers or small recreational vehicles and want a low-effort, reliable way to prevent battery drain. It fits users who prefer a compact, weatherproof maintenance solution that mounts to glass or connects directly to the battery, and who value automatic voltage control and multi-chemistry compatibility. If you need a portable, warranty-backed trickle charger to preserve battery health between rides or trips, this model offers a simple, durable option.
