An intelligent battery charger suitable for flooded and gel lead acid batteries including deep cycle batteries at 6V, 12V or 24V. The microprocessor controlled unit provides 4 stages of charging, Soft Start, Bulk Charge, Absorption and Float which assists in the batteries life expectancy and performance. An auto detection feature provides a user friendly experience, which can be pre-programmed or manually set for greater control. Should a blackout occur or AC input power be lost during a charging operation the memory function will resume charging once power is re-established. Other features include temperature/voltage compensation, reverse polarity/short circuit protection and a battery status indicator. Ideal for cars, motorcycles, caravans and boats with battery capacities between 20-200Ah. It's also ultra-portable with a handy storage pocket in the back for the leads. NOTE: These chargers are not recommended for long-term "maintenance" charging of unsealed lead-acid batteries, the types with removable filler caps and liquid elctrolyte. Long-term continuous float charging of this type of battery may cause loss of water from the electrolyte, ruining the battery. If you are intending to use this charger on these batteries please use an appliance timer such as MS6113 to automatically limit the charging to 30 minutes or so per day.
