3-in-1 Smart 7-stage Car Battery Charger, 12V, 2A/4A/8A

Model Number: EP12M248-A1 Brand Name: Everpower Key Specifications/Special Features: Main features:。 High efficiency (>85%)。 Selectable charging rates to suit battery capacity。 Selectable battery type。 Temperature self-compensation: charging voltage adapts totemperature to prevent over or under battery charging。 Capable of recharging severely discharged or heavily sulfated battery。 Reverse polarity protection, short circuit protection, sparks free contact。 Ultra low input power consumption while in standby mode。 Ease of useClear charging status display
。 Full microprocessor controlled
。 Does not overcharge your battery even if it is kept connected in maintenance float mode

Step1: desulphation:
。20% charging LED: on
。Engage high peak pulse for deep-discharge or sulphated battery
。Dissolve the lead sulphated crystal bring the electrolyte fluid towell-distributed state
。Battery voltage will increase slowly

Step2: soft start:
。20% charging LED: on
。Battery voltage will increase slowly

Step3: bulk:
。80% charging LED: on
。Battery can be charged about 80%
。Charger delivers an almost constant current 2000mA until the battery voltage reaches the set value

Step4: absorption:
。80% charging LED: on
。Battery can charge up to almost 95%
。Charging current tapers and the charging voltage are kept constant at the set value

Step5: test mode
。Charging is interrupted for a short period while battery voltage is measured
。If the battery voltage falls too quickly, the battery could be faulty
。Full LED: flashing

Step6: recondition charging
。Charger will go into this stage if battery fails Test Mode due to its condition, age or being under charged
。This stage can recover batteries from deeply discharged state increasing performance and battery lifespan
。Full LED: flashing

Step7: float mode
。Full LED: on
。Float mode allows the charger to effectively be left connected to your batteries, it works at a safe level and readyfor use
