Deltran Battery Tender Jr Maintainer - 12V, 0.75A, Lead Acid & Lithium

The Deltran Battery Tender Jr is a 12-volt, 0.75 amp battery maintainer designed for 12V flooded, AGM, gel, calcium, EFB, and lithium (LiFePO4) batteries. It’s tailored for keeping smaller batteries in peak condition during prolonged periods when they’re not in use, suitable for motorcycles, lawn mowers, and other powersports vehicles.

This smart battery charger runs a multi-stage charging cycle that transitions smoothly from bulk charging to a maintenance float mode. Its automatic operation adjusts to the battery’s needs to avoid overcharging, which is especially important for maintaining the longevity of lead acid and lithium chemistries. The modest charge rate makes it perfect for smaller batteries, effectively supporting those in the lower amp hour ranges.

On the safety side, the unit features spark-free connection and reverse polarity protection, so you can hook it up with confidence. It’s built for connect-and-forget use, allowing continuous maintenance charging without supervision.
