Intelligent Pulse Repair Battery Charger Parameters: 1.Input Voltage:110-230V2.Output voltage: 12V/24V3.Current:10Apeak for 12V,8A peak for 24V4. Suitable capacity: 30-120AH5.Power:160W6.Frequency: 50-60HZ7.Length of output wire:65cm8.Length of input wire:125cm9. Dimension:14*19*7cm10.Gross weight:0.9kg11.Application: best suitable for 40-120AH lead acid batteries(including wet and dry) Multiple protectionsOverheat protection:The charger will close automatically without current output for protective purpose when its temperature is over 105, and when the temperature is decreased below about 80or power supply is shut down for 10 minutes, charging process can be resumed.Short circuit protection:In case of accidental short circuit, the charger will close automatically without current output, and beep for alarming. Once correctly connected, charging process will be resumed.Reverse connection protection:Whenever positive poles and negative poles of the charger and the battery are not connected correctly, the charger will close automatically without current output, and beep for alarming. Once correctly connected, charging process will be resumed.Low voltage protection:When single cell voltage is below 1.5V, the charger can not be started up, and beep for alarming. This mechanism is to avoid possible damages caused up by voltage discrepancy between the battery and the charger. Five-stage charging mode What this chargercan be used for ? As show in thepicture Charging operationStep 1, Examine and make sure rated voltage of battery is conforming to output voltage of charger.Step 2, Connect correctly the charger and the battery.Step 3, Examine and make sure mains supply voltage is conforming to input voltage of the charger.Step 4, Connect mains supply and the battery, watch to see if the indicator is on and the cooling fan is working when charging.Step 5, if the charger refuse to work, turn off mains supply immediately and check all the connecting cables between mains supply, the battery and the charger.6AH battery ~ 1 - 3 hours 7AH battery ~ 2 - 4 hours9AH battery ~ 3 - 5 hours 10AH battery ~ 4 - 6 hours20AH battery ~ 5--8 hours 32AH battery ~ 6--10 hours36AH battery ~ 8 - 11 hours 45AH battery ~ 9-13 hours55AH battery ~ 11--16 hours 60AH battery ~ 13--18 hours80AH battery ~ 15--20 hours 105AH battery ~ 16--25 hours120AH batteries are more analogousTroubleshooting :One: the charger on the battery charging time is only a few minutes, or even shorter time, has shown full power state.1: Check whether the charger is working because of overcurrent, overtemperature protection, or low voltage protection (there is a non-matching voltage) to see if the cooling fan is working properly.2: that the battery has no capacity or has been fully charged (recommended to be re-tested after discharge, or use another battery shortage test)3: It is recommended to try adding a battery replenisher or distilled water.4: Check the charger output clip and battery column contact is good.Two: charging the battery when the battery shell heating or charger for a long time still can not show full work.1: Check whether the battery short circuit phenomenon, resulting in long-term charging voltage can not reach the charger voltage set value.2: the battery has been leakage phenomenon 0.3A current.3: battery production process, material failure, it is recommended to use genuine battery.4: Please replace the battery with a good re-test.Three: the charger when charging the normal connection when the buzzer alarm or not working at all.1: Check the battery voltage is a serious loss of power, resulting in low-voltage charger protection (there is no match voltage).2: battery long shelved so that the old (belonging to the waste battery) or internal resistance, the battery serious short circuit.3: Whether the no-load status is still buzzing when the power is connected.4: it is recommended to replace the battery to re-test.Special Note:A: Charger 12V can be charged but connected to 24V battery when also indicated on the 12V indicator, while the 24V indicator does not work.Charger 12V voltage range of recognition in the 8V-14V, 24V voltage identification range of 18V-29V.Second: the charger in the battery charge when working, the cooling fan must work properly.If you find the cooling fan does not work or damage, overheating can cause damage to the machine or other components, please repair and repair.Three: charge the battery for a long time (or about to scrapped) or a small capacity battery.The charge indicator may not show the charge status (because the shelf life is long or the internal battery of the used battery is large and the demand current is small). The user can turn on the headlamp or motorcycle headlamp for a few minutes, then let the lights turn on (power) while using the charger to charge the battery, and the charge indicator will flash. (The general charge indicator light can be extinguished after th
