12V/24V 60A 7 stage Automatic Car RV battery Charger for AGM GEL WET Rechargeable Battery Charger With LCD Features: 1.LED digital display : U-I-C-P U:battery voltage I:charge current C:7 charging stage code P:over heat protection 2.LED indicators : AGM /GEL /Lithium battery 3.AGM/GEL/Lithium battery charge mode selection 4.Numerious protection function: overheat, over charge, short circuit, soft start, internal temperature compensation, reverse polarity, over charge protection. 5.7 Stage automatically charging: C-1-Desulphation: The desulphation stage may break down sulphation that occurs in batteries that have been left flat for extended periods of time, returning them back to full charge. Sulphation occurs when lead-sulphate hardens and clogs up the battery cells. C-2-Soft-Start:A preliminary charge processes that gently introduces power to the battery.This protects the battery and increases battery life. C-3-Bulk(Constant Current):Bulk mode charges the battery at the maximum rate (constant current)putting a large amount of power into the battery in a short amount of time.This stage will charge the battery to approximately 80%,until the voltage reaches 14.4 volts for 12V battery or 28.8volts for 24V charger. C-4-Absortion(Constant Voltage):The charge rate slows down so the battery can absorb more power and reach 100% charge. The voltage remains at a constant 14.4 volts for 12V charger or 28.8 volts for 24V charge while the current is gradually reduced until no more power can be added without over-charging the battery. C-5-Battery Test:An automatically battery test is conducted immediately after the absorption stage. The test monitors the voltage for 90 seconds to determine if the charge was successful. C-6-Recondition:The battery reconditioning function is initiated automatically in the case that the battery fails the battery test (stage 5). Failing the battery test indicates that the absorption stage was unable to fully charge the battery. The recondition mode will then begin to introduce a low constant current for a period of 4 hours. Then the charger will go into the float charging mode. This recondition stage can recover batteries from a deeply discharged state increasing performance and battery life. C-7-Float:The float stage maintains the battery at 100% charge without overcharging or damaging the battery. This means the charger can be left connected to the battery indefinitely.
