Product Details
- 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.
- 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

Customer Questions & Answers

Question:
What is the Battery Tender Junior 12V Charger and Maintainer, and how does it work?
Answer: The Battery Tender Junior 12V Charger and Maintainer is an automatic charging device designed specifically for powersports vehicles like motorcycles and ATVs. It features a 750mA output which effectively maintains and charges lead-acid batteries without overcharging. This device continually monitors the battery status and switches to a maintenance mode once fully charged, ensuring optimal battery care. -
Question:
How is the Battery Tender Junior more efficient than traditional trickle chargers?
Answer: Unlike traditional trickle chargers that continuously supply a fixed charge, the Battery Tender Junior employs smart charging technology. It automatically adjusts the charging process based on the battery's state of charge, meaning it provides power only when needed. This not only conserves energy but also enhances battery lifespan and prevents damage caused by overcharging. -
Question:
Can I use the Battery Tender Junior for all types of batteries?
Answer: The Battery Tender Junior is designed primarily for 12V lead-acid batteries, including sealed lead-acid, gel, and AGM types. However, it is essential to avoid using it with lithium batteries unless specifically stated by the manufacturer. This model is perfect for maintaining the health of your motorcycle or ATV battery during off-season storage or idle times. -
Question:
What safety features does the Battery Tender Junior include?
Answer: The Battery Tender Junior is equipped with several safety features, including reverse polarity protection and short-circuit protection. These features prevent accidental damage to the battery and the charger itself, ensuring safe operation during use. The compact design also makes it easy to store and use in various environments, thereby enhancing user convenience. -
Question:
How long does it take to charge a typical motorcycle battery with this device?
Answer: Charging times can vary based on the battery’s size and condition, but generally, the Battery Tender Junior can fully charge a typical motorcycle battery in 8 to 12 hours. It's designed to bring your battery to full charge efficiently while balancing maintenance needs, making it suitable for busy users who may not frequently check battery status. -
Question:
Is the Battery Tender Junior suitable for winter storage?
Answer: Yes, the Battery Tender Junior is ideal for maintaining batteries during winter storage. Using this charger ensures your battery stays fully charged without the risk of freezing or sulfation, which can damage batteries in cold weather. This makes it an essential tool for anyone storing their motorcycle or ATV outside during colder months. -
Question:
How do I properly connect the Battery Tender Junior to my motorcycle battery?
Answer: To connect the Battery Tender Junior, first ensure your motorcycle is turned off and remove the battery cover if necessary. Attach the red lead to the positive terminal and the black lead to the negative terminal. Ensure the connections are secure before plugging in the charger. This ensures a safe charging process and helps maintain proper battery health. -
Question:
Can the Battery Tender Junior be left connected to the battery indefinitely?
Answer: Yes, the Battery Tender Junior is designed to be left connected to your battery for extended periods. Its smart charging technology automatically switches to maintenance mode once the battery reaches full charge. This provides continuous monitoring and care without the risk of overcharging, making it perfect for seasonal vehicles that don’t see regular use. -
Question:
What is the size of the Battery Tender Junior and is it portable?
Answer: The Battery Tender Junior is compact and lightweight, typically measuring about 4.5 x 3.9 x 1.9 inches, making it highly portable. Its size allows for easy storage in toolboxes or luggage, and you can take it with you to maintain batteries wherever needed, whether you’re at home, in a garage, or on the road. -

Battery Tender Battery Chargers 021-0123 Editorial Review
The Axtra 3.6 amp battery charger maintainer is recommended by an auto mechanic with 40 years of experience over the Battery Tender 0.75 amp for small to medium size 6 volt and 12 volt batteries. The Axtra charger also has more functionality with both 0.9 amp and 3.6 amp outputs. It can't fully charge a lithium battery. The polarity of the cables doesn't matter, and the charger can be used on deep cell batteries. Leaving the charger connected to a motorcycle battery for an extended period of time may cause the electrolyte level to drop. The garage door opener may have an outlet in the ceiling for those that lack outlets on garage walls. Customers have had mixed experiences with some saying the electronics failed and corroded, while others thought it was the best battery maintainer.
