Single battery or pair

It's listed as a single battery, but it looks like a specific buyer got two by mistake. Must have happened in a packaging mix up.

One battery. You can use a LiPo which will give you longer battery life and more speed.

Single, not a pair. I was kind of tricked as well. Still a decent price and great product. They are left or right side. Make sure you use loctite on this easy 10 min install.

If you have already the original battery you only need one spare...battery gives you enough capacity for switching them on charge...

I have seen them listed in pairs but mostly they are sold as a single unit. You need two minimum to work. This listing should be clear.

Try this link http://24hourbattery.com/ . I just purchased some button cells. You can purchase one battery or all the way up to a case quantities. Most other sites require you to purchase in two packs, at a much higher price.

Yes, One is enough... Make sure you tap the end where it connects to battery. The Led wire come apart...

one AA battery (i recommend Duracell batteries: they are the best for a long session and really pack a punch ;-D)

Lone enough. You can always get an extension for them. They are a great product, just buy 'em and enjoy!

Only one, but it lasts a long, LOOOOONG time on a charge. I always wear out before the battery does.

It depends. I have received a pair and a single. I probably bought from different sellers. They work Great. I would assume 1only to be safe.

You can hook up kore than 1 battery. You can also use car batterries but the performance will be significantly better with deep cycle batteries.

I bought a pair although there were single lights available (their descriptions indicated the side of the vehicle).

It takes one AA battery. You can buy them just about anywhere. What's the problem?

There is only ONE battery. My suggestion is to change it and you should be good to go.

One battery. Price has come down a bit since the last one I purchased through Amazon.
