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.
