Reliable 6V/12V Charging With Maximum Safety

Vehicles today are often equipped with a wide array of power-robbing accessories such as GPS navigation units, stereo sound systems, video players, daytime running lights, and many other electrical convenience functions. All these items place a high demand on a vehicle's battery which can lead to discharge, sulfation, or acid stratification. The best way to ensure reliable starting of your vehicle is to keep a regular check on the battery charge--especially in vehicles not used year-round, such as motorcycles, convertibles and classic cars. Battery chargers from Bosch are first aid for exhausted batteries and return them to top condition.

Everything you need is integrated and/or included in the box.

The Bosch Battery Charger and Maintainer is a smart charger operated by a MCU processor that provides state-of-the-art charging technology that allows the charger to interact with and respond to the condition of the battery. It modifies its charge action based on the feedback from the battery in order to provide a high quality charge that restores sulfated and discharged batteries to their original capacity without under- or overcharging.

The Most Intelligent Battery Chargers

Since it is a smart charger, it will automatically detect the voltage of the battery and select the proper series of charging stages based on the needs of the battery. It can be left connected to the battery and will switch to the maintenance charging mode when the battery voltage falls below 12.8V. The float and maintenance cycles are repeated indefinitely to keep the battery at full charge without overcharging.

Unlike manual and automatic battery chargers that treat all batteries the same no matter what condition they are in and charge with a steady, unregulated current, the Bosch Battery Charger and Maintainer uses SmartAMPS Technology, the optimum charge current depending on the battery’s condition and the current charging stage, to provide a fast, high quality charge that ensures the longest life of your battery.

One-Button Smart Charging

You do not need to be a specialist to use the Bosch Battery Charger and Maintainer. Simply attach the two insulated charger clamps integrated into the opposite end to the appropriate battery posts of the lead-acid battery being charged or maintained. Then plug in the AC power cord, integrated at one end of the charger, to a standard 110-volt household outlet. Finally use the mode button to select from 4 charging modes to instantly begin charging. Its is as easy as connect, plug in, and turn on. For extra convenience the included charger mounting hook allows you to hang the charger upright in the best spot possible between the battery and the AC power source.

The Safest Charger to Use

Safety is an important concern around any power source. One-button operation, built-in pulse and maintenance charge function, and a comprehensive safety concept make the Bosch C3 Battery Charger and Maintainer very safe to use. If an abnormal situation occurs, such as when the charger is incorrectly connected or there is an abnormal charging time, the charger switches automatically to standby mode to protect the battery from damage. Additionally the charger is designed to protect against spark, short-circuit, reverse polarity, and overheating, making this the safest charger you can use.
