Battery Tender 6V/12V 2 AMP Battery Charger — Selectable Lead‑Acid & Lithium, Automatic Maintenance Float

Battery Tender’s 6V/12V 2 AMP selectable charger charges and then safely maintains lead‑acid and lithium powersport batteries to prevent overcharging during storage.

This compact charger is designed for motorcycles, ATVs, snowmobiles, lawn tractors and other powersports equipment that need reliable charging and long‑term maintenance. It automatically detects selected voltage, supplies controlled current, and switches to a maintenance float mode to preserve battery health while preventing the common risks of trickle charging. The unit includes both ring terminal and alligator clip connectors, and is certified to North American safety standards for dependable everyday use.

How does the selectable 6V/12V function help my vehicle batteries?

Selecting the correct voltage ensures the charger matches the electrical system of your battery so it delivers the right charging profile. The ability to choose either 6V or 12V makes the charger versatile for a range of small vehicles and seasonal equipment. Proper voltage selection reduces stress on battery cells and supports a full charge before transitioning to maintenance mode.

• Manual 6V or 12V selection to match battery type and vehicle system
• 2 amp output balanced for powersport batteries without overheating
• Automatic switch to float/maintain once fully charged

Will this charger work with lead‑acid and lithium batteries?

The Battery Tender 2A charger supports common 12V lead‑acid chemistries including flooded, AGM and gel, and it also accommodates compatible lithium battery types when selectable settings are used per manufacturer recommendations. The four‑stage charging process helps optimize charge without overdoing it, which is important for different battery chemistries.

• Compatible with 12V flooded, AGM, and gel lead‑acid batteries
• Selectable modes to support lithium batteries when specified
• Four‑stage charging: initialization, bulk, absorption, and float maintenance

What safety and monitoring features are included?

The charger uses solid‑state electronics and a two‑color LED indicator to communicate charge status and voltage conditions, so you can see when the battery is charging, fully charged, or if voltage drops require resumed charging. It includes protections to prevent overcharging and is certified to ETL, FCC, and other standards for electrical safety and emissions.

• Two‑color LED shows charging state and maintenance mode
• Automatic resume of full charge if battery voltage falls under load
• ETL US/CSA, FCC, ICES, and BC certifications for safe operation

How easy is the charger to install and use?

Setup is straightforward: choose the correct voltage, connect either the ring terminal or alligator clip, plug it in, and the charger handles the rest. Its low‑maintenance design is tailored for busy owners who need reliable overnight or seasonal charging without constant monitoring. The included accessory cable gives flexibility for both permanent and temporary connections.

• Includes ring terminal and alligator clip accessory cable for different hookups
• Plug‑and‑play operation with automatic float maintenance
• Compact housing for easy mounting or storage when not in use

Who is this for? This Battery Tender charger is ideal for owners of motorcycles, ATVs, snowmobiles, riding mowers and other small engine vehicles who want a dependable, compact charger that supports multiple battery chemistries and switches to safe maintenance mode. It’s a good fit for seasonal vehicle storage, hobbyists who perform their own maintenance, and anyone who needs a simple, certified charger to keep batteries ready without overcharging.
