We have a board that uses a solder pad for one of the contacts of a button battery and had no problems when we were washing the boards. We are now using a no-clean flux and find that on a bunch of boards there is a coating of flux covering the pad s

If you put a 6v battery on a 12v solar panel, it will charge the battery. It will also overcharge the battery and may damage the plates if you leave it on too long. The 'float' voltage for a lead acid battery (6v) should not exceed 7.2 volts for exte

The point is to charge the battery during the day, then completelty drain it at night by use of a light sensor.. I thought that due to the low current of the solar panel it wouldnt be a problem if i used a 6 Volt battery.. do i hook + to - or + to
