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. **Q: What size batteries can this charge? Is it good for small motorcycle batteries?** A: 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. **Q: Will the Battery Tender Junior work on my Harley-Davidson?** A: 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. **Q: What is the difference between this and a trickle charger?** A: 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. **Q: Will this charge a completely dead battery?** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just plug n play.
