Battery Tender Junior 12V, 800mA Maintainer

- Switchable battery type: Lead-Acid or Lithium (LiFePO4)
- Automatic charge cycle to keep battery ready for use
- Smart ISM microcontroller adjusts charging strategy
- Includes: 12V charger, ring terminal and clips; 5-year warranty
This junior option adds lithium compatibility, expanding applicability to riders using LiFePO4 packs. The button-selectable mode makes it versatile for ATVs across battery chemistries while maintaining safe, automatic operation.
Battery Tender 800 (SuperSmart) Charger

- Encapsulated interior for moisture and shock protection
- Automatic SuperSmart charging with spark and reverse polarity protection
- Compact size with 800mA output for small to mid-size batteries
Designed for durability in tough storage conditions, this model blends protection and consistent current delivery. It is suitable for snowmobiles, ATVs, and similar small to mid-size batteries, offering reliable maintenance without hassle.
Battery Tender Plus 12V 1.25 AMP Maintainer

- Fully selectable 6V or 12V maintenance mode
- Keeps lead-acid, flooded, AGM, and gel cell batteries healthy during storage
- Auto float mode and “connect it and forget it” operation
- 11 feet of total reach for flexible placement
The Plus line with the 1.25A rating provides substantial charging power for larger ATV batteries while preserving chemistry integrity through automatic float maintenance. It is a practical choice for riders who park their vehicle for extended periods.
Buying Guide
- Battery chemistry compatibility: Ensure the charger supports your ATV’s battery type (lead-acid, AGM, gel, or lithium). Some models offer cross-chemistry support, but verify before purchase.
- Charging current and battery size: Higher amperage chargers charge faster but may be unnecessary for small batteries. Match the output to your ATV battery’s capacity (Ah) for optimal results without overworking the pack.
- Maintenance features: Look for auto float mode, 4-step charging programs, and reverse polarity protection to safeguard both battery and charger.
- Ease of use and wiring: Features like ring terminal harnesses, long cords, and quick-connect options add convenience, especially for hard-to-reach batteries on ATVs or stored locations.
- Durability and warranty: ATVs are often exposed to dust, moisture, and vibration. Encapsulated designs, moisture resistance, and longer warranties signal better long-term value.
- Size and portability: For storage or garage use, compact units save space while still providing reliable maintenance.
- Safety certifications: Check for certifications related to energy efficiency and safety. A unit with spark protection and short-circuit protection reduces risk in busy garages.
When evaluating options for ATVs, prioritize models that automatically switch to float mode after charging and support the battery type used by your vehicle. In environments where storage and off-season periods are common, a robust maintenance charger helps preserve battery health and readiness for the next ride.
