what's the extension tube for? does it mean that you can use 2 batteries instead of 3?

No. Two batteries instead of ONE battery. You definitely want too use the extension and use two batteries. If not the battery will drain too quickly. Very bright even brigther than $100.00 streamlight. Battery life is half that of streamlight. You will have to recharge frequently.

I own 2 of these lights. It's 3 instead of 2. You want to use the extension and use 3 batteries because this flashlight uses a lot of power. Try to buy your 18650 batteries in multiples of 3... such as a dozen.

I found that the replacement batteries are junk and i have had 3 of them go bad. But I happened to open up a laptop battery and they have 6 to 9 batteries in them that are the same. I have about 20 of these batteries charged and use them for back ups. THis light will not last an hour with the stock batteries.

Yes, you use it with two sections or three sections. The one pictured above does not come with a battery. It is the bare tool.

I only have two batteries and it has worked well with them. Maybe you could fill two at a time?

probably means 2 batteries in the pack - that is how mine came. Do not know for sure.

When you use 3 AAA batteries, you don't need that tube but when you use one rechargeable 18650 battery, you slip that tube around the battery before putting it in the flashlight so that it fits better.

No it's so you can hook to two batteries so you don't run the one battery down

Yes they do work well in my extension where it allows me to take more pictures when I put 2 batteries in it.

Sorry Pierre, don't have a clue. I thought in the beginning it was to hold extra batteries. They fit but it won't close properly.

You can use either one. It comes with an adapter so you can use it without batteries.

Correct. They send you an extender to use with the USB battery (it is too long to use without it) and the cartridge for the AAA batteries. Both come with.

It came with two batteries, that's why I thought it was a good deal. You can buy extra batteries if you like.

Uses 2 AA batteries; don't purchase if used- the one I bought skipped so much it's worthless.

There are two batteries in this combination. Both are 3.0 ah. Ideally it would be nice to have an additional battery if you are using both tools so that you don't have to switch batteries when on is charging.

You can buy 2 extra batteries but you also need to buy the plastic battery box they go into... there are higher output batteries available to give you extended range. I would install the upgraded batteries and use the originals as a spare (still need to buy another battery box). There is no room to 'double up' the batteries.

The tube is If you want to use a long rechargeable battery Instead of the Cartridge you put 3 triple A's in

When I ordered the TR-3T6, it was supposed to use either two (2) or three (3) batteries. It will only use (2) because I did not receive the extension necessary to make it a (3) battery unit. I am not at all satisfied with this unit and would not recommend anyone to purchase the unit. Whenever I do try to use the unit, it becomes very hot to the touch and the batteries will not last any length of time. Maybe my unit is defective, however, they will not replace it....
