IVT PL-782B, 12V Lead Acid Battery Charger With Refresh,1500mA, 5-120Ah

The device begins with a very low battery voltage of 1.5 V in the charging process. As a result, even discharged batteries are charged. The charger charges according to the UI charging process, i.e. the charging current decreases as the battery voltage increases. As soon as the charging current falls under the maximum value (1.5 A), the device begins the pulse operation. Both in charge mode and in the preservation charge mode, short current pulses are given in the battery in order to reduce harmful sulphate deposits on the lead plates. This regenerates the already damaged battery as well as significantly increasing its performance and operating life. The efficiency of the pulse operation is all the more higher the longer the battery remains connected to the device. This function also benefits from reconditioned batteries. Here you can avoid the emergence of these sulphate deposits in advance and will therefore experience the full power of the batteries. When the typical charge closing voltage of 13.8 V is reached, the device switches to preservation charging. The charger is suitable for continuous operation.
