I made an interesting discovery today I have 2 BatteryMinders that keep 2 batteries fully charged and I decided to put my amp meter to see how much power I am using to do this. The regular batteryminder drew about .2A while the batteryminder plus drew about .225A Now I also haqve a float chargwer that I got from
www.pulsetech.com that maintains another battery that I have. I found that this uses so little power I cannot get a reading on my meter. My guess from looking at the meter it would be something like .05A. All batteries were fully charged and the chargers were in the float cycle. At .15cents per kw if my math is correct the pulsetech is saving me about $2 per month
