The HF Charger series is a group of advanced battery chargers designed specifically for high performance 12V, 14V or 16V sealed lead-acid batteries. These chargers combine the reliability of a High Frequency MOSFET rectified assembly with an advanced microprocessor control board to create a battery charger that can rapidly and safely recharge 12V, 14V and 16V maintenance free, deep cycle, gel-cell, and AGM (Absorbed Glass Mat) batteries in several sizes. Three Stage Charging At the heart of the technology in all HF Chargers is the three distinct charging stages. During the first stage, called "Bulk" charging, the current is fixed and the voltage is allowed to float. During this stage, 80% of the battery's capacity is restored. When the battery's cell voltage is up to the correct level, the second stage called "Absorption" charging is engaged. During this stage the voltage is fixed and the current is allowed to float. The battery is brought to 100% during this stage and the cells are equalized. The third stage is "Float" charging. During this stage the voltage and current are reduced to a level that will maintain the battery indefinitely. Several microprocessors are used to tightly control the entire process. This is the same technique that battery manufacturers recommend and use in the production of new batteries and it is the fastest and safest technique for battery charging. Compatible With Most Lead-acid Batteries Including AGM Lead-acid batteries have different charging requirements based on their specific design. Overcharging will reduce the life of any battery as sealed valve regulated batteries are especially sensitive to high charging voltages and overcharging. Overcharging an AGM or gel-cell battery will cause permanent damage. Voltage Monitoring The battery's terminal voltage is measured every five minutes by the on-board microprocessors and this information is analyzed in addition to the elapsed time to dynamically control the battery charger for optimum charging performance. Automatic Computer Analysis/Auto Shutdown The microprocessors will analyze the battery when connected. If the battery's voltage is below 4V the charger may not recognize the battery is connected and will not begin charging. Likewise, if the battery will not come up to the correct voltage in a ten-hour period the microprocessor control board will automatically shut the charger off. UL Approved Battery Cables Six feet of durable battery cables are provided that are resistant to cuts and abrasion. The copper plated battery clamps are compact and custom designed easy connections. All clamp connections are soldered for maximum current flow. Internal Cooling Fan A cooling fan automatically operates during charging to keep the circuit and other internal components at a constant safe temperature.
