Deltran Battery Tender Junior 750mA 12V Motorcycle Battery Charger & Maintainer

The Battery Tender Junior is the maintainer a lot of riders grew up with, and for good reason. Hook it to your motorcycle before winter storage, plug it in, and walk away. It brings the battery up to full charge, then switches to a float/maintenance mode that holds it there for months without overcharging, so the bike fires right up in the spring.

At 750mA it is sized for powersports batteries from 3Ah to 30Ah: motorcycles, dirt bikes, ATVs, UTVs, personal watercraft, snowmobiles and lawn tractors. Unlike a basic trickle charger that keeps pushing current into a full battery, the Junior watches the battery and only delivers what it needs.

It comes with Battery Tender's two-in-one alligator clip and ring terminal cable. Leave the ring terminals on the bike's battery and you can plug in through the SAE quick disconnect in seconds, without pulling the seat every time.

Key Features

• 4-stage ISM charging: initialization (health and polarity check), bulk charge, absorption and float maintenance.
• Safe to leave connected: automatically switches to float mode after a full charge, and resumes full output if the battery voltage drops under load.
• Temperature compensated: charge voltage adjusts for cold and hot storage conditions.
• Two-color LED shows the charging stage at a glance.
• Spark proof, reverse polarity protected and short-circuit protected.
• Over 12 ft of reach with the 10.8 ft DC output cord and 1.5 ft accessory cable.
• Quick disconnect system: works with Battery Tender's SAE extension cables and accessories.
