These are cool, but I didn't know the pipes had end caps and you can't connect them to each other so I was a bit disappointed.

They are awesome, but they use the small round batteries, which I found difficult to replace. Now they sit without batteries and not so awesome anymore until I get the right replacement battery.

Unusable on garden tractor sized batteries, ends are to small will not fit on post.

Does the job, but in my 283s it was a bit of a tight fit. Also, it lacks any markings as to battery orientation, which could be a bit of an annoyance if you don't have an old one for reference.

I have not had them in an all day use scenario yet so I can't speak to the how long they last. But they fit my radio well and are working. if they last as long as original smaller capacity batteries did when they where new I'll be happy.

As mentioned in a prior review they DO NOT have a small tab to prevent them from being installed the wrong way so pay attention. If the had the tab I would have given 5 stares.

Larger than other iphone batteries batteries. No end cap to protect, which makes carrying this with you difficult.  Price is good, but the lack of cap to protect the end of the battery as well as the more "bulky" size are drawbacks.  A good "extra" extra battery overall, but not one you want to keep attached to the iphone.

These batteries are a little longer than the standard 18650's, they do not fit in my e-cigarette...but have other uses for them.

It looks OK, but since it is not solid, it has end caps to cover both ends, some of the end caps are loose.

If these used AAA batteries I would be more interested, but instead it uses small calculator style batteries. Not good for an emergency. The other end has a whistle which is great, but the cap falls off and was lost before it ever arrived. There are better emergency light options.

The remote I got I could not put in rechargable battery's in it they would not go all way down inside the slots so I called and they sent me another remote which worked better so I had some regular AAA battery's they fit fine for the original remote that came with it.

Fits. Just remember to remove the screw caps at the end, they can be a bit hard to remove.

Didn't fit the 20V batteries I have, due to those little tabs at the front end.  Had to buy a Chinese knock off to work with actual DeWalt batteries.

Batteries are kinda puffed up, as though their plastic cover was inflated.  As a result, they're a tighter fit than the stock battery.  I bit of extra plastic from the seams as well, but that can be trimmed with scissors.

I bought these as replacement for old batteries in Senheiser 830 TV earphones.  They were specified for this headphone.  One of them stuck in the earphone and could not be removed.  The fit was not exact.

This battery is smaller and the terminals are slightly recessed so I had to make some adjustments, but they work.
