Problem With Float Charger For Sump-Pump Batteries?
Instead of the quiet whirring sound of a fan when in float stage, the
charger has recently begun emitting a louder "whining" sound. The fan's revolutions also seem to slow down when this happens. It returns to normal if I insert a finger quickly and contact the fan. But it often resumes "whining." At this moment, it's nice and quiet, but the noise mode is occurring more frequently? Is this damaging or dangerous? Does it need a new fuse? Thanx, Jack |

If you'd like to change the fuse, go ahead. Or you might put a new
thermostat in the living room. But if it was my gadget, I'd do neither of those. I'd do something much more likely to fix the problem. Yes, it's damaging. Yes, it can well be dangerous. -- Christopher A.

Unless you fix it, it will seize one day, maybe burn out, possibly start a fire, but unlikely. A new fuse will do nothing since it is already working (getting electricity). Why the hell would you have a fan in the charger, or is it a separate fan that goes on when the batteries charge? Take the charger cover off, put 2-3 drops of 10 weight oil (or Turbine oil if you have some) on each end (bearing) of the fan motor, spin by hand, blot to remove the excess oil. Probably will fix it for another few years. Otherwise, buy a new charger/fan. Whatever floats your boat. |

What's kind of charger uses a fan anyway? I have an old Sears auto
charger, 2/10/50 amps. The 50 amps is for temp starting only, but 10 is continuous and it has no fan. I wouldn't think you'd need one too much bigger for use on sump pump batteries. |
