The Schumacher SEM-1562A-CA 1.5 Amp Speed Charge Maintainer is a unique AC powered automatic charging accessory for use with everything from smaller batteries designed for motorcycles, tractors and mowers, to standard car / truck batteries and marine / deep cycle batteries. Designed around an internal microprocessor which constantly collects information from the battery that the unit is attached to, the SEM-1562A-CA effortlessly and quickly ensures that your 6 and 12-volt batteries are maintained at optimal levels, and does so in the fastest and most convenient means possible.
Microprocessor controlled charging and maintenance is simply the easiest way to keep batteries at optimal power levels. This convenience and speed is experienced from the moment that the SEM-1562A-CA is connected. First, the unit utilizes the user's choice of either easy-to-connect and remove battery clips, or permanent ring terminals (both included), each of which allows for charging or maintaining of batteries whether they be in or out of vehicles. The SEM-1562A-CA also features automatic voltage detection which allows it to automatically determine whether the connected cell is a 6-volt battery or a 12-volt variety. This eliminates the possibility of damaging a battery due to choosing the wrong charging settings. Once your battery type has been identifified, a multi-phase charging process kicks in which plays out via the unit's automatic Charge / Maintain modes. Tipped off by the data analyzed by the onboard microprocessor, your battery is supplied with a constant charge until it reaches a preset level - at which point charging ceases. Eventually, if the charge falls below a certain level the SEM-1562A automatically transitions into Maintain Mode, delivering a small, safe charge that will raise the battery's level back to where it should be.
In addition, because of the constant monitoring the battery, the SEM-1562A can react to charging needs swiftly, efficiently and accurately, allowing charging cycles to click on and off in the same way. Because of this, batteries can be left attached to the SEM-1562A-CA indefinately for storage without the risk of overcharging and/or damage. Additional features include: automatic temperature compensation which adjusts the maximum charge voltage and maximum maintain voltage based on the ambient air temperature; thermal runaway, which automatically reduces the current if it detects the battery may be getting too hot; an auto-start feature that keeps power from flowing unless a proper connection exists, or in the case of a reverse hook-up; and a Desulphation mode for charging batteries left discharged for an extended period of time.
