[QUOTE="roys, post: 498691, member: 5044"] Very seldom would we just replace one faulty battery in a bank of batteries we would replace the whole bank, point being the batteries need to be fairly well matched for optimum safety and performance. I have seen the result of a battery going into reverse polarity many years ago and it wasn’t pretty. I actually had to ask one of the cleverer blokes to explain the failure as I didn’t understand it at the time. Max Voltage of the motor should be stamped on the name plate, and barring failing bearings and or brushes if it is a universal motor, there is very little else that will deviate the motor from the name plate details. So max watts, current, rpm should be accurate. [/QUOTE]
