I usually charge my trailer batteries with this old Motomaster charger from Canadian tire that does 12v/6amp or 12v/2amp charging and I have 210 amps battery so I charge it with the 6amp option but ive noticed that even though the meter says its 100% if i put the fridge on the night before a trip when I load up the next morning my battery is at 50% the fridge is only drawing 2 amps per hour. Also this motomaster charger meter seems to just move around everytime I pickup the charger to look at it. Anyway long story short I took a black and decker charger with me this time and connected it to the plug in my boler and directly to the battery, what I didnt realize was that the black and decker charger charges at 1.2amps and so I ended up running out of charge and my fridge turned off.
Looking for battery charger recommendations please:
