The RYOBI 2 Amp Battery Charger & Maintainer keeps your motorized vehicle battery at a peak charge level, allowing your battery to sit idle without any worry that it is dead or damaged when you need it. It’s ideal for use on any vehicles you don’t use daily such as recreational vehicles, motorcycles and boats. For use over long periods of time, the maintainer features a float mode function that charges the battery to optimal levels, automatically pauses charging to monitor battery levels and only resumes charging when the battery needs an extra charge. This protects the battery so you will never worry about overcharging or undercharging. Choose between semi-permanent mounting eyelets or use the battery clamps for quick and easy setup. It is compatible with lead-acid, lithium, AGM and deep cycle 6V and 12V batteries, easily switching from 6V to 12V with the push of a button. The LED indicator lights display battery status, reverse polarity warnings and informs you if you have a defective battery. Reverse polarity protection assures clamps are connected correctly to the battery, ensuring safe use. For added convenience, this battery charger and maintainer features a 9’ total cord reach. The 2 Amp Battery Charger & Maintainer is backed by the RYOBI 3-Year Manufacturer’s Warranty and includes the 6V/12V 2A Battery Charger & Maintainer, Battery Clamps, Semi-Permanent Mounting Eyelets and an Operator’s Manual.
