Battery Tender 10-Bank 6V/12V 4A Selectable Battery Charger

If you've got multiple vehicles, motorcycles, or other equipment sitting around, keeping all those batteries topped off can be a real chore. The Battery Tender 10-Bank charger is designed to handle that exact situation, letting you manage up to ten batteries at once. This unit is built to keep your batteries in peak condition, whether they're for a daily driver, a classic car, or seasonal toys.

This charger is incredibly versatile, working with a wide range of battery types including lithium-ion (LiFePO4), AGM, gel cell, sealed maintenance-free, and flooded lead-acid batteries. It supports both 6-volt and 12-volt systems, and each of the ten banks can deliver a solid 4 amps. The charging process is a complete 4-step program that brings the battery up to full charge and then automatically switches to a float mode. This float mode is key for long-term storage, as it maintains the proper voltage without overcharging, preventing damage and ensuring your battery is ready when you need it.

Beyond its charging capabilities, this unit is built with safety and convenience in mind. It features reverse polarity protection to prevent damage if you accidentally hook it up wrong, and a 25-hour safety timer shutoff for added peace of mind. It's also spark-proof, making connections safer. The design is compact and lightweight, so it won't take up much space in your workshop or garage, even if storage is tight. This charger is a solid option for anyone needing to maintain multiple batteries over extended periods.
