Battery Wrap - Does this look ok?

[DallasLiza]

One of my 18650 batteries had a snag so I did my first re-wrap. I thought I had it positioned well before turning on the hair dryer but seems I got way more wrap on the pos end than on the neg end of that Samsung 30-Q. Here it is next to an original wrap. There's not much wrap at all on the negative end. Do you think it's ok or should do over?

Should not be an issue as long as contacts are made in mod. Extra coverage not a problem.

Agreed. The negative end looks fine to me, although you may want to hit it with a little more heat to smooth out that wrinkle towards the top of your photo. Positive end will be fine as long as it makes good contact.

Ok, thanks. I'll do that right now.

any wrinkles you have could get caught on something and rip so you need to address those - but this is especially important up at the top.

Get heavy duty wraps next time.

I agree with the rest. It looks fine to use, but keep an eye out for the extra material on the positive end catching and tearing. Nicks there are especially risky.

Congratulations on your first rewrap! It looks much better than mine did.

Haha, thanks. Now I'm thinking I'll probably use it once then re-wrap and do a better job.

Blue is Junkle's favorite color .

I haven't done it a lot, but am catching on. I got a batch of wraps that were just too long, and trimmed about 2 millimeters off of them before putting them on the battery to avoid too much material at the ends. I've also learned to hit them hard and fast with a lot of heat to melt/shrink the plastic before the battery warms up. At first I tried it slow and gradual and got a warm battery with un-melted wrap.

Yours look very tidy!
