Can I leave this connected to my motorcycle all winter without damaging the battery?

Yes! Battery Tender Junior switches to float/maintenance mode at full charge, offsetting self-discharge to keep at 100% without overcharging or damage. Unlike trickle chargers, it adjusts output to battery needs for safe long-term storage.
What size batteries can this charge? Is it good for small motorcycle batteries?

Battery Tender Junior 750mA is ideal for 3–30Ah batteries in motorcycles, ATVs, UTVs, scooters, PWCs, and snowmobiles. Safely charges small 3–5Ah batteries overnight and larger 14–20Ah motorcycle batteries in ~14–22 hrs.
Will the Battery Tender Junior work on my Harley-Davidson?

Yes, Battery Tender Junior works with all Harley-Davidson 12V models, including Sportster, Softail, Dyna, Touring, CVO, and Pan America. The 750mA output is ideal for Harley batteries, and the included harness allows easy plug-in charging.
What is the difference between this and a trickle charger?

A trickle charger delivers constant current and can overcharge a battery during storage. The Battery Tender Junior is a smart charger that automatically switches to float mode, charging only when needed for safe long-term maintenance.
Will this charge a completely dead battery?

Battery Tender Junior can recover most deeply discharged batteries using low-voltage recovery during startup. Batteries below 2V or left discharged too long may be permanently damaged. Red LED = charging; flashing red may indicate a bad battery.

Stay Charged: Battery Tender battery chargers and maintainers provide a full charge to your powersport vehicle’s battery before switching to float mode to maintain proper voltage levels for safe, long-term storage
Extend Battery Life: Compatible with all 12V lead-acid, flooded, AGM, and gel cell batteries. Complete 4-step charging program (Initialization, Bulk Charge, Absorption Mode, Float Mode) allows for optimization of battery power, without overcharging or battery damage. Smarter than a trickle charger.
Includes: 12V, 750mA battery charger and battery maintainer with 12-foot output cord, fused-ring terminal harness for hard-to-reach batteries and alligator clip accessory cables, 5-year warranty, and lifetime customer support
Simple & Safe: Low maintenance, easy-to-use, universal battery charger is just 3.3 x 1.3 x 2.4 inches, 1 lb (charger only). Spark-proof circuitry ensures no-spark connections, and automatic reversed hook-up detection verifies correct connection
Monitor Power Levels: Two-color charge status LED light indicates the state of the charge and if the battery voltage drops too far under load, adaptive charging will resume full charger output power. Automatic charge cycle functionality switches to float mode after fully charging the battery
