Troubleshooting Battery Chain Circuit for Motor Operation

Click For Summary

Discussion Overview

The discussion revolves around troubleshooting a battery chain circuit designed to operate a motor. Participants explore potential reasons for the unexpected discharge of multiple batteries in the circuit setup, focusing on wiring, component integrity, and battery types.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant describes a circuit configuration where multiple batteries are connected in series to power a motor, expressing confusion over the discharge of five out of six batteries.
  • Another participant acknowledges the wiring method as acceptable but finds the rapid discharge of the batteries unusual.
  • A third participant suggests testing the switch for proper functionality, warns against soldering directly to batteries due to potential damage, and raises the possibility of accidental wire contact.
  • Concerns are raised regarding the type of batteries used, with a mention that typical dry cells have a long lifespan while rechargeable batteries like NiCad can self-discharge over time, implying that a reason for the discharge must exist.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the cause of the battery discharge, with multiple hypotheses presented and no definitive resolution to the issue.

Contextual Notes

Participants did not specify the type of batteries used, which may influence the discussion. There are also unresolved questions regarding the integrity of the switch and the potential for accidental short circuits.

Hello, I'm new here, and I need help with a problem. I'm sure there is a really easy answer to this, but I don't know what it is. I can't find it googling, probably because it is so obvious to everyone else.
But I have a circuit, which requires multiple batteries to opperate. Too combine their voltage, I had the negative terminal of one soldered to the positive of the next, so one and so one in a chain. Then the positive end of that chain I soldered a wire, connected it to a motor, and then through the other part of the motor, to a switch, back to the negative end of the chain. But I had found, after leaving the switch open overnight, that 5 of the 6 batteries had not voltage (according to a multimeter), did the batteries discharge each other, or do they need the circuit to be closed for that?
Any help whatsoever would be very much appreciated.

If you truly have everything hooked how I read it from your description then it seems strange that you would have 5 dead cells after a short time. This is an acceptable way to wire batteries.
 
Okay, thanks a lot then!
 
As per the last if what you say is accurate then there appears no clear reason.
1) can you test your switch to make sure it is open when it is supposed to be
2) I do not recommend soldering directly to batteries it is possible to damage them
3) is it possible that wires were accidentally touching
You did not say what type of batteries were used but typical dry cells can last several years , and rechargeables like Nicads can self discharge but usually only over months, so if they did discharge then there was a reason however unlikely.
