I've rewound a transformer to deliver 500V DC pulses using a 555 timer but from a previous reply from one of the senior forum members this is too high. The locally import battery chargers we get from China are expensive and they don't do what they claim should happen ie multi stage charging.įrom some docs downloaded from Wikipedia and other sites, it seem that PULSE CHARGING SHOULD DO THE TRICK if high current/voltage pulses could be managed ie: magnitude, pulse rate etc. I have a need since after replacing my UPS batteries, I have a number of 2nd hand that I want to charge. We also have promotion season and will give discount for new customer.Ī: Yes, we could provide free samples and deliver with freight collected.I have scoured the net, sites like battery university and nowhere can I find any real info on what voltage, current, charge, discharge times to create a pulse charger for a 12V SLA battery. We hope you can inquiry the bottom price based on your quantity. Q: Is the price on this page your final price?Ī: The price on this page is only for your reference. ![]() Highly recommended:In the winter(under 0✬), use automatic mode to charge fully first ,then use manual mode for 0.5 to 1 hours.Ī: We could accept L/C sight, T/T and Paypal.Ī: We could deliver the goods within 20 days after order confirmed. Manual: It can be used for small capacity ,low temperature(under 0✬) and large internal resistance the battery, charging current is bigger than automatic so it take less time than automatic, but there must has human monitoring to avoid damage battery,when the battery shell has high temperature must stop charging, but using manual mode won't spend more than 1 hour.Īutomatic:Pulg AC power first then connect battery with charger, it will recognize voltage automatic,intelligent and convenient. The Difference Between Manual And Automatic Mode: Trickle charge mode:When the battery voltage and current is approaching the set voltage and current ,it will turn to trickle floating charge from automatic mode ,it means full-charged,also can be charged with floating mode. No-load mode: When there has no load connected with charger,the LED screen will show voltage only,the power is about 2W Ĭonstant current: It means the battery voltage is lower than the set voltage of charger,then the charger supply constant charging current to maintenance both battery and battery charger Ĭonstant voltage: Advanced pulse width modulation(PWM) technology, control the charger's current and output voltage accurate, avoid overcharge įloating charge mode:When the battery is going to be full-charged,the charger will stop charging ,but still supply constant floating voltage and small current to battery Use manual mode no more than one hour, when battery heat ,you must stop charging immediately. Advanced pulse width modulation(PWM) technology is used to automatically charge batteries through a 4-stage charging cycle.ĥ. LED display show charging current, voltage and charging percentage, when it connect battery only, it test your battery's real voltage.Ĥ. Intelligent charging step,identify 12V or 24V battery automatically, input AC power 150-250V, 50/60HZ.ģ. This device is widely used in 12V or 24V 6AH to 150AH lead acid batteries including AGM,GEL,WET,Ca batteries.Ģ. ![]() Don't block cooling hole nor use the charger with the cooling fan off.ġ. The 12V input when automatic charging mode,full electric voltage of 13.8V to 14.3V, about 16V input when manual charging mode,must be artificial monitoring in case of overcharge in manual mode charging, suggest stop charging when the battery is beating.ħ. When the red indicator light of charging stops flashing or is dark,and as well as the current indicator fell to about 1 bars condition,the charging mode will change to floating charging, means the battery chargine being finished.Ħ. Constant voltage charging will be arranged to provide various protections and avoid over-voltage,over-current,over-heating and electrode-positive, etc.ĥ. The battery life can be significantly improved by digital pulse repairing method for the power chips of microcomputers.Ĥ. Advanced pulse width modulation (PWM) technology is used to automatically charge batteries through a 4-stage charging cycle.ģ. ![]() wet batteries and maintenance-free battery.Ģ. This product is applicable to the 12V/24V 150AH lead acid battery, including GEL, UPS. Switch for charging current adjustment:12V 10A-24V 5Aġ. User-friendly screen:LED indicates power,charging status,full,fault,battery type and charging mode Fully automatic microprocessor controlledħ-stage charging:include bulk-absorption-float
