I have this old Century battery charger. Probably brought it from Montgomery Wards. Model 87062. 12v/6amp, 12v/2amp, 6v/6amp. Chasing down a problem with MIL's
lawnmower. I was trying to turn a brand new starter (Toro electric start) and I could with a battery reading 13 volts. With the battery charger, i tried to start the starter at the 12v/2amp setting and nothing happen. Switch, by chance to the 12v6amp setting at it turned nicely. Connect a Harbor Frieght mutilmeter and discover the following.
Setting: 12/6amp Output: 12.06 volts DC
12/2amp 10.43 volts DC
6/6amp 7.38 volts DC
So the 12/2 setting is [censored]. The unit has a build date of 01/97.
Two questions I want answered,
1. Anyone care to recommend a battery charger I hardly use? (It is so hard to get opinions from this forum). I have purchased a Noco Genius G3500 for maintaining lawnmower and scooter batteries. Just want a car charger in case battery dies in Chicago winter that will get me though a cold spell or a charge or two until I by a new battery or the nieghbors need help.
2. Since it is my belief that a battery charger is suppose to have slightly more voltage than the battery it was charging, what happen when I tried to charge 12volt batteries with a charger putting out 10.43 volts. I often used the 12/2 setting, as this is a manually only charger and I had the fear of overcharging.
