Cobus as we discovered the other day Trojan have a few different spec sheets for each batt the one I linked earlier said 15.5 per batt. The charger you have can do the job at 15.8v. I say give it a go and get a Battery Hydrometer and measure the specific gravity of each cell after a charge. http://www.ctek.com/int/en/chargers/MXS 5.0 Volt 12V Rated Voltage AC 220–240VAC, 50–60Hz Charging voltage SMALL, NORMAL: 14.4V, COLD/AGM: 14.7V, RECOND: 15.8V Min battery voltage 2.0V Charging current 5A max Current, mains 0.6A rms (at full charging current) Back current drain <1Ah/month Ripple <4% Ambient temperature -20°C to +50°C, output power is reduced automatically at high temperatures Charger type 8 step, fully automatic charging cycle Battery types All types of 12V lead-acid batteries (WET, MF, Ca/Ca, AGM and GEL) Battery capacity 1.2–110Ah up to 160Ah for maintenance Dimensions 168 x 65 x 38mm (L x W x H) Insulation class IP65 Weight 0.6kg Temperature Compensation Built in charge voltage compensation according to ambient temperature
July 29, 201610 yr Author viper, thanks for the advice, I think you're probably right. I might even get a couple more of them if it works. I think I looked at the T1275 and not the T1275Plus. The Plus model has a lower equalisation voltage.
August 18, 201610 yr @cvzyl if you go for the 8 Volt Trojan batteries then you could do an equalization charge by removing 1 battery and adjusting your infini bulk charge voltage. Does anyone think that there will be merit in connecting the 12 volt batteries in parallel to allow them to equalize to the same voltage?
