The MXS 3.8 is an advanced microprocessor controlled battery charger with patented Float/Pulse maintenance for use on batteries from 1.2Ah up to 85Ah. The MXS 3.8 solves a broad range of battery problems and is the ideal charger for everyday use. Features of the MXS 3.8 include diagnosis of battery condition to establish if it can receive and retain charge, patented automatic desulphation programme and a special Snowflake mode for optimum charging on cold winter days. The Snowflake modes operates on the 3.8A program. Wide charging range on all lead-acid battery types from 1.2Ah up to 80Ah with additional maintenance capability to 130Ah. Splash proof and dust proof (IP65). Patented Float/Pulse maintenance means the MXS 3.8 ideal for long-term maintenance. The entire process of battery testing, charging and maintenance is easily followed on the clear LED display.The MXS 3.8 is a fully automatic connect and forget 12V charger with 7 charging steps and offers selectable 0.8A, and 3.8A programmes. The MXS 3.8 is easy and safe to use, protects vehicle electronics, is spark-free, reverse polarity protected and short circuit proof. The MXS 3.8 features a 5 year warranty.Fully automatic for optimal chargingFor all lead-acid batteries6 FULLY CHARGED BATTERY7 Maintenance chargingPROGRAM for charging small batteriesPROGRAM for charging normal batteriesFor charging in cold conditions and AGM batteriesTECHNICAL DATACHARGING VOLTAGE: 14.4/14.7 VCHARGING CURRENT: Max 3.8 ATYPE OF CHARGER: 7 step, fully automatic charging cycleTYPE OF BATTERY: 12 V lead-acid batteriesBATTERY CAPACITY: 1.2-85 Ah, up to 130 Ah for maintenanceINSULATION: IP65 (splash and dust proof) STEPS:- STEP 1: DESULPHATIONPulsing voltage removes sulphates from the lead plates of the battery restoring the battery capacity.- STEP 2: SOFT STARTTests if the battery can accept charge. Charging begins if the battery is OK- STEP 3: BULKCharging with maximum current until approximately 80% battery capacity.- STEP 4: ABSORPTION, BATTERY READY TO USE Charging with declining current to maximize up to 100% battery capacity. – STEP 5: ANALYSETests if the battery can hold charge. Batteries that cannot hold charge may need to be replaced.- STEP 6: FLOAT, BATTERY FULLY CHARGEDMaintaining the battery voltage at maximum level by providing a constant voltage charge.- STEP 7: PULSE, MAINTENANCE CHARGINGMaintaining the battery at 95 – 100% capacity. The charger monitors the battery voltage and gives a pulse when necessary to keep the battery fully charged.TECHNICAL DATACHARGING VOLTAGE: 14.4/14.7 VCHARGING CURRENT: Max 3.8 ATYPE OF CHARGER: 7 step, fully automatic charging cycleTYPE OF BATTERY: 12 V lead-acid batteriesBATTERY CAPACITY: 1.2-85 Ah, up to 130 Ah for maintenanceINSULATION: IP65 (splash and dust proof)
