I don't believe there is a good way to boost the voltage output on the stock chargers, simply because the voltage is built based on the secondary turns of the transformer and load resistance. Capacitor only helps as a filter to smooth the output, mostly. I have one dirty idea, but I don't know what the implications of it would be, so I'm throwing it out there for everyone else to pick it apart: Remove one battery out of the circuit and charge for an hour. This reduces the load resistance a little and gives you some overvoltage to desulfate the 5 batteries. Then swap the 6th in to perform the same on the last one, which you may want to do after a normal usage cycle. This idea allows you to leave all of the components in place without exceeding their specifications, as long as you don't do it after a deep discharge that would allow the charger to draw too much current on either side of the transformer. Sounds crazy, even to my liking, but it might work!

I run the NiCDs, and I really should charge them to 45 volts, not 42 to blow the oxygen off the plates every once in awhile.Change the capacitor a bit? How about a boost transformer on the input (I could try a variac I have around). I already buck 240 to 208 on my car, I should be able to boost a bit. But how much?C_______________________________________________Elec-trak mailing listElec-trak cosmos phy.tufts.eduhttps://cosmos.phy.tufts.edu/mailman/listinfo/elec-trak |
