Junior Selectable 12V Charger by Battery Tender

• tercraft with Lithium upgrades
• Snowmobiles
• Any vehicle being upgraded from lead-acid to Lithium where a single charger is needed for both chemistries
• Any 12V lead-acid or Lithium battery from 3Ah to 30Ah

Future-Proof Your Charging Setup

The shift from lead-acid to Lithium in powersports is underway — many manufacturers now offer Lithium as factory standard or as the recommended upgrade. A standard lead-acid maintainer left connected to a new Lithium battery delivers the wrong charging profile. The Junior Multi-Chemistry handles both chemistries correctly today and remains compatible as the fleet transitions over time.

Automatic Temperature Compensation

Charge voltage adjusts automatically based on ambient temperature for lead-acid applications, ensuring correct charging in cold storage and preventing overcharge in summer heat. No manual adjustment required at any temperature.

Safety Features

• Spark-proof connection — No current flows until polarity and connection are confirmed correct
• Reverse polarity protection — Automatic shutdown if clamps are reversed, protecting Lithium battery management systems and vehicle electronics
• Short-circuit protection — Automatic fault detection and shutdown
• ETL and CETL certified

The Right Chemistry, Every Time

Lithium batteries represent a significant investment — they cost more than lead-acid and deliver more in return, but only when maintained correctly. The Battery Tender® Junior Multi-Chemistry ensures correct charging regardless of which chemistry is connected, with the same Battery Tender® quality and ISM intelligence that has protected batteries since 1965.
