Main Features:Compact & Delicate & Energy Saving -- Switch Mode TechSmall and light,as we adopt the switch mode technologyor called Switching Power Supplytechnology. Compared withtraditional Linear Powertechnology, ours is more energy saving as more than 85% electric energy is transferred to battery chemical energy duringcharging process while traditional tech can onlytransfer 40%.The tech is suitable for all types of lead acid batteries (wet,flooded, maintenance free, VRLA, AGL,AGM, GEL, etc) as well as lithium, lipo batteries.
Automatic-- MCU controlMCU system is applied. The whole chargingprocess is monitored. Multi-stagechargingautomaticallyproceeds.No need for manual interference.
Automatically stops charging when the battery is full. You can leave the charger connected to the battery infinitelywithout the risk of overcharging. once the battery is full, the charger monitors the battery's voltage intermittently. If battery'scapacity decreases or voltage dropsunder set level, the charger can start again to charge battery to its full.Multi-stage charging--full charge but never overcharge& save battery & save energyMax 8 stage: pre-charging, soft charging, main charging (bulk charging), secondary charging, high constant voltage charging (absorption charging), 3-minute test, Float charging, End maintenance charging.
This way can well transfer electricity into battery according to battery's absorption ability. On the one hand, save energy; on the other hand, protect battery from over-charging, therefore less gassing lesstemperature rising.Floatcharging and End maintenance charging also help protect battery and prolong its lifetime.
Recover BatteryCapacity--Pulse & Reverse Pulse TechPulse and reverse pulse technology is applied. The chargergenerates pulseand reverse pulse to reduce battery'simpedance,gassing and temperature rise,restore the sulfate into liquid to recover battery capacity, therefore toprolong its lifetime. Pulse charging also can help charge fast and fully.Pulse Charging might not be applicable to Lithium, Lipo, Li-ion battery, which need constant current to charge.
Digital Display& IndicatorOur charger has 4-digital display and 2 setLED indicators.
Digital display will show battery'svoltageand chargingcurrent and error code and more information. Float charging will have time count-down, so that user knows when battery can be ready.LED indicators will show pulse and reverse pulse charging.The display and indicator can be customized or re-defined.
More ProtectionTester function: If battery has abnormal state, the charger will display error code and remind User to check battery whether it is good or bad.Polarity Protection: Prevents the output leads from sparking due to accidental reverseconnection or short circuit.
Overchargeand Over-voltage Protection: never worry about overcharging or over-voltage as chargerautomaticallystops when battery reaches set voltage or current
CustomizationWe can change parameter to meet different applications. Make charger specifically for your battery.
CE and RoHS CertificationWe have CE and RoHScertification. The model has passed SAA test and has C-tick approved.
WarrantyWe design our charger for 3 years and offer one-year warranty.
