WINTOOLS 2-Quart Battery Water Filler Bottle with Auto Shutoff

About this product

This WINTOOLS filler bottle is a straightforward maintenance tool for flooded lead-acid golf cart and deep-cycle batteries with removable cell caps. The two-quart polyethylene jug uses a spring-loaded, double-action valve tip intended to deliver water quickly and stop automatically when the cell reaches the proper fill level. That makes it useful for owners who maintain individual cells directly instead of using a single-point watering manifold. The valve tip is also designed to reduce after-drip, which helps keep battery tops and the surrounding tray cleaner. Before using it, confirm your batteries are serviceable flooded lead-acid units and follow the battery manufacturer’s instructions for when to add water and what fill level to maintain. Use distilled or deionized water only. This tool is not appropriate for AGM, gel, sealed lead-acid, or lithium batteries, and it should not be used to add acid during routine maintenance.
