24 Volt 40 Amp Smart Battery Charger


EPS 2440 Battery Charger is compact and light-weighted. It is a 4-stage charger designed for all types of lead-acid batteries. The term 4-stage refers to the three charging stages along with the additional stage, equalization. The three stages include bulk, absorption, and float. In the bulk stage, the charger remains a constant current while the voltage increases. Around eighty percent of the battery capacity is recharged in this stage. In the absorption stage, the battery voltage maintains at a level instead of increasing, and the battery current drops. The last twenty percent battery capacity is recovered. In the absorption stage, both the battery current and voltage maintain at a level. The voltage maintains so that the charger does not over-charge the battery. The 4-stage charger has the equalization mode, which aims to prevent the electrolyte from stratifying. The voltage and current are brought up a bit to equalize the electrolyte and remove the sulfation.
