How can you tell which end is positive and which is negative? I can't see any + or - on the sides, and there are no bumps on the positive ends.

Since they are installed in the shaver I cannot look at them, but do you have a volt meter?

On mine there is a small + sign on one of the batteries close to where both batteries come together

Use a voltmeter. If the needle goes positive then the red lead wire is positive.

Check polarity with a small DC voltmeter or multimeter. When the + (usually red) lead is connected to the positive side of the battery, the meter will register a voltage reading. If the leads are reversed, the needle will try to deflect backward.

Mine has three terminals, + - L. "+" is the positive source to the battery. "-" is the negative to the battery and negative to the load. "L" is the positive to the load. If yours is different, good luck.

Both sides are flat, it makes it somewhat difficult to determine which side is (+) and which is (-) but there are small markings on the side of the battery

Wires hook to the posts on coil , one side is negative and other side is positive

Usually you use the two outside terminals or whichever ones are marked + and -. Polarity does not seem to matter to the charger.

Typically the white or dash-dot wire is positive and the unmarked black one is negative. As to the plug itself, the center pin is positive and the shield is negative. Of course, it is always best to test with a volt meter but this is standard electrical wire code.

All it is saying is to connect the LiPO connector with the positive leads facing the +. Start at - and how close you get to + depends on how many cells the LiPO is. Hope this helps :)

Yes, + and - signals. One wire has Monster Marking on it the other has no markings

When you cut the strip you get a positive and a negative tab for each side...so if you have a strip pre-cut, you have a positive and a negative tab on one end and another positive and negative on the other end.

I used the one labeled "pwr in" AND has the Positive (+) and Negative (-) symbols

The two I got at different times are both oriented as "both ends oriented the same way." The images are inconsistent. The 3/4 view image that's featured in the listing shows them as flipped, while the top view image displaying as I'm replying right now show them oriented the same way. Judging from other answers it appears there is no guarantee what you'll get.

There is no positive/negative wire. One end goes into the outlet and the other goes into the device.

Polarity is embossed on the ceramic substrate with traditional symbols of positive and negative. If you can't locate, use s multi meter as it is a diode and only passes current from negative to positive

Absolutely no writing or markings. One side is textured and the other is side is smooth and clear. Hope this helps.

Only showing one side. try doing a search for the other side, another seller may have it

Center-tip-negative polarity is not the norm, easier to buy one here. You'll see one in the "customers...also bought" links--e.g. Planet Waves 9V Power Adapter, which has the polarity you need. Just make sure any adapter you use is "center tip negative".

See Karlberg's comment. Also, both studs are for Positive inputs. There are no Negative (ground) terminals.
