Battery Tender Plus 12V 1.25A Smart Battery Charger & Maintainer — Selectable 6V/12V, Multi-Stage Float

The Battery Tender Plus 12V 1.25A is a smart charger and maintainer that fully charges 12V powersports batteries and automatically switches to safe float maintenance.

This compact, lightweight unit from Battery Tender is built for motorcycles, ATVs, snowmobiles, scooters, and other powersports vehicles. It delivers a higher charging rate than the Junior model to replenish batteries faster, then holds them at optimal voltage with an automatic float mode. Rugged safety features include spark-proof lead connection and reverse polarity protection, and the selectable design supports 6V or 12V systems and most lead-acid battery types.

How quickly will this charger restore a depleted powersports battery?

The 1.25 amp charge rate gives a faster charge than many trickle chargers without risking overcharge thanks to its automatic multi-stage control. Charging time varies with battery capacity and state of charge, but the unit completes the bulk charge and then transitions to a maintenance float to preserve battery health.

• 1.25 amps of regulated charging for quicker replenishment
• Automatic multi-stage control: bulk, absorption, and float
• Compatible with 12V lead-acid, AGM, flooded, and gel batteries
• 50% more power than the Battery Tender Junior for faster topping-up

Is it safe to leave connected for long-term storage?

Yes — once a full charge is reached, the charger switches to a float mode that supplies minimal current to keep the battery at proper voltage without overcharging. Built-in protections make it spark-proof and guard against reverse polarity, helping prevent damage during hook-up or extended maintenance.

• Automatic float-mode maintenance for months-long storage
• Spark-proof lead connections reduce hookup hazards
• Reverse polarity detection prevents accidental misconnection
• Lightweight, compact housing for easy mounting or storage

Which batteries and vehicles will this unit work with?

The Battery Tender Plus is designed for 12V powersports batteries and also has selectable 6V/12V capability for flexibility. It supports most lead-acid chemistries, including standard flooded cells and maintenance-free types like AGM and gel.

• Ideal for motorcycles, ATVs, UTVs, snowmobiles, scooters, and PWCs
• Works with flooded, AGM, and gel lead-acid batteries
• Selectable 6V/12V for different vehicle needs
• Good choice for seasonal storage or intermittent use

What practical features make it easy to use?

The charger is designed to be plug-and-play: connect the leads, select the proper voltage if needed, and let it manage the battery automatically. Its compact form factor fits in small storage spaces, while the durable enclosure and covered connections simplify installation on a variety of vehicles.

• Simple hookup with quick-disconnect harness or ring terminals
• Compact, lightweight design stores easily with tools
• LEDs or status indicators display charge progress and faults
• Industry-leading 5-year warranty for long-term confidence

Who is this for? Riders, powersports owners, and anyone who stores vehicles seasonally will benefit from the Battery Tender Plus 12V 1.25A charger. It’s well suited for people who want faster charging than a trickle charger, reliable long-term maintenance without monitoring, and built-in safety features for peace of mind when hooking up batteries in garages, sheds, or workshops.
