Output Voltage is the key factor in a voltage regulator designed specifically for Lithium batteries. The ideal charging voltage for Lithium batteries is 13.9-14.2VDC. This regulator has a carefully set output voltage of 14.1VDC (+/- 0.1VDC). This stable and ideal output voltage carefully keeps a lithium battery in it’s ideal charging range.
Battery condition is important. No regulator can make up for a bad or weak battery. If in doubt charge your battery and have it load tested, or simply replace it.
