Hello, I have this CTEK Polar charger http://ctek.com/pt/en/chargers/MXS 5.0 POLAR The CTEK list the COLD modes for this charger. Where is the AGM option? In warm weather I do not need 15V ! Manual lists the COLD mode that the voltage is up to 15.00v but most small VRLA 12v AGM batteries like YUASA NP12-12 are listed for 14.5 Volts not 15.00 volts. Questions: 1. What mode should be used for VRLA/AGM UPS battery. 2. Can recondition be used for these batteries.
