Unwrapping damaged wrap with metal tweezers. Short??

I recently got new wraps for two batteries that have slightly damaged wraps, I used a metal tweezer to remove the old wrap. I started from the postive side placing the tip of the tweezer between the old wrap and the white insulator ring being very careful not to touch the positive end with the metal tweezer. Then I came across a youtube video saying that it should be removed from the negative to avoid a short.

So, as long as I did it without any sparks showing or anything, is that enough to be sure that no short happened? and are these batteries safe to use?

Even if you had shorted all it would have resulted in is a spark. ... now i guess if you held the tweezers in the ark long enough there could be an issue. ....

But then you wouldn't be posting the question.

Yes, removing the wrap from the bottom is preferable for that reason.
If you dead short the battery you would have noticed, it's would have heated up in your hand real fast and possibly send some sparks.

I wouldn't do it personally with metal tweezers but if you didn't see a spark or any burn mark your fine. Just use your finger nails or ceramic tweezers. also it is better to do it from the negative

The only time it becomes an issue using metal is if you were to touch the negative and positive at the same time. and basically the whole battery is the negative minus the top pin which is the positive. if you did cross them though it likely would have exploded, so you are fine, but in the future just be safe and use ceramic tweezers ;)

I've seen a car battery explode because someone crossed the negative and positive when installing it because their all metal wrench slipped and it was an instant explosion and pretty bad.

Thanks, but the tweezer never touched anything but the insulator ring and wrap so I guess everything's fine right?

Thanks for all the info I'm glad that the batteries are fine because I didn't want to replace new batteries just because of the thought that it may have shorted with me noticing.

you would have noticed for sure if it did

It not going to explode via incidental contact..... you would have to hold the tweezers in contact with both positive and neg for a while before that happens..... most people will flinch and break contact when the spark happens. The spark being the only explossion.

Yeah this is exactly what got me confused, It makes perfect sense that touching both the postive and negative sides with metal object will short the battery, but how about only touching the positive side with a metal tweezer? can this cause a short? and if no, why is it preferable to peel the wrap from the negative side?

Too avoid incidental contact......there are allot of fearful people on these sites... I think electricity and technology scare them.....
They like to over react to risks and hazards.

I peel wraps differently. I take a sharp razor blade and cut the wrap in half. Starting in the middle of the battery I make a light pressured cut from the middle, to the negative end of the battery. Then I pull back the wrap to expose the bottom end and grip it in one hand, and peel the wrap off with the other. Pretty easy.

The entire outer casing, or "can" (under the wrap), minus the positive pin... is the negative pole of the battery. That's a large part of why there's a wrap. It limits the exposed negative to that uncovered bottom. Starting the cut from the bottom/neg avoids the accidental shorting to the pos pin that you're concerned about. That's just good practice.

Just touching the pos wont "short" unless that contact continues in a circuit to the neg.

Even just holding both ends is likely fine, though I'm careful not to do it.
Our bodies aren't terribly great conductors, without some help, but I still never did play the "touch a 9v battery to your tongue" game.
Different people have different hobbies. :rolleyes:
