The Battery Tender Power Plus by Deltran is a 3.0 Amp fully automatic battery charger and maintainer designed for 6V and 12V lead-acid batteries. This Costco-exclusive model (part number 022-0202-COS) is user-switchable between 6V and 12V, making it versatile for motorcycles, ATVs, cars, trucks, SUVs, boats, personal watercraft, lawnmowers, and other vehicles. It supports battery capacities from 1.2 to 200Ah.

The charger uses a complete 4-step charging program consisting of Initialization, Bulk Charge, Absorption Mode, and Float Mode. Once the battery reaches full charge, it automatically transitions to float/maintenance mode to safely keep the battery topped off indefinitely without risk of overcharging. It is compatible with all standard lead-acid battery types including flooded, sealed maintenance-free, AGM, and gel cell batteries.

Built-in safety features include reverse polarity protection and spark-proof technology for easy, worry-free connection. The compact brick-style housing includes LED indicator lights for quick status monitoring. The kit includes SAE adapter cables with a fused ring connector that can be permanently wired to a vehicle battery for convenient connect/disconnect. Input is 120V AC at 60 Hz.
