Battery Tender 6V/12V 4A Lead Acid & Lithium Selectable Battery Charger

This Battery Tender charger comes with the charger itself, a set of battery clamps, and a ring terminal harness. It's designed to keep your 6-volt or 12-volt batteries topped off, whether they're lead-acid or lithium types. This is a really handy tool for anyone who doesn't drive their vehicle regularly, or for storing seasonal equipment like motorcycles, classic cars, or boats.

What makes this charger stand out is its selectable battery chemistry feature. You can choose the right charging algorithm for your specific battery type – whether it's a standard flooded lead-acid, a sealed AGM, or even a lithium battery. This ensures you're charging safely and effectively, which is important for getting the most life out of your battery. The 4-amp output is a good balance, providing enough power to charge efficiently without being overly aggressive for sensitive battery types.
