mine thaks three but flashlight switch does not last long then it fails and you have nothing. needless to say i don't like my 3800. however, yours should have three bulbs. hope this helps and your switch don't fail.

You can charge 2 or 4 batteries, but they must be charged in pairs. You cannot charge 1 or 3.

I don't know 'exactly' how long it lasts but I'm real pleased. I use both the rechargeable 18650 3.7v battery and 3 AAA batteries 4.5v. 3 AAA's are a bit brighter. Both types seem to last a month or more of frequent use. I just got back from a 2 month vacation and it did not run down while is was out of the country. Very bright and long lasting. That's my opinion.

I don't have the flashlight so guessing, but it's probably for the 18650 battery as it's narrower than the 3 AAA batteries

Going by the comment section I ordered 3 batt. The reason for doing this was to have an extra battery because I was going to be away from any charging source for 3-4 days. Two of the battries were good the other one loses it's charge quickly.

Not sure sorry I use it to charge 4 18650 and 18350, excellent charger though

Regarding dimensions, if you use the adapter for AAA batteries, it slides right in. If you use the single 18650 battery, then you place it first into a slider plastic tube to make up the difference in size. It includes the tube.

This add is only for two batteries. I bought a Nitecore Intellacharger i2 for charging. It's not too expensive and charges almost any battery you can think of.

I don't know the right mAh, but I happen to have an 18650, and it's been working well. Mine is 3800 mAh, 3.7 V Li-ion. I'm not an expert on this, please try it on your own risk.

An 18650 rechargeable. Do not put 2 18350's in there. They will fit but it will destroy the light.

I purchased 3.7V 18650 3000mah Rechargeable Batterys. They seem to work well. I've used them for about a year so far.

I have this set-up and it works well with 2 batteries. I have been pleasantly surprised at how long I am able to burn the 600 in this configuration. Purchase the dual charger as well.

The one pictured has only 2. However, all 24v B&D batteries, whether 2 or 3, are compatibe. I have nearly all of the B&D tools and have purchase every 24v battery that has been offered. Regardless of whether a battery has 2 or 3 prongs it will work. The possible exception is that in some cases there is a very small piece of plastic molded in that has to be removed--cut or filed off.

NO! I don't know what those other two reviewers got, but the ones I received does not allow the 18650 batteries to go in. SonOfUncleSam hit it right on the nose.

1 18650 battery. You can get a two pack with a charger on Amazon. These are amazing.

Wanda I seem to be having the same 'length' problem as you. My units overall length without the extension tube is220mm, which like yours is too short. I guess 'size' does matter. :p Currently I am using 1ea 18650 and 2ea 18350 batteries all stuffed into the thing. Its working so far

No. The site suggested "additional items" includes the required batteries. These units require the 3.7V 18650 batteries that are a little bigger than a AA battery. The 18650 battery size actually comes in multiple voltage options so be careful what you order. The 3.7V is best but watch out for the lower voltage batteries. All of them should be rechargable. My batteries hold a charge for quite a while. Hope this helps.
