18650 Battery vs Normal AA Size Battery

  • Clement0401 Friday, August 21, 2015 8:47 AM Reply
    I intend to purchase UltraFire SH98 910lm 3-Mode White Light Zooming Flashlight w/ Cree XM-L T6 - Black (1 x 18650) from DX. It is using 18650 Battery. Can the normal AA Size battery be use on this flashlight? If it can be used, will I still able to achieve 910lm? Will the life-spend of the battery shorten?

    It is best Clement, when enquiring about a particular product, to post on the product's own forum page but since we are here, we need to identify the product exactly. Part of the URL does not do that, we need all of it or at least the SKU number. Are we talking about SKU: 162491?

    A single AA cell will not do the job of an 18650 Lithium cell. The size is different for a start. 18650's are 18mm diameter and 65mm long- much bigger than AA's and they are 3.7 volts, versus the AA's 1.5V. All 18650's are rechargeable and a special charger is needed for them.

    You are welcome Clement. Selecting a new type of torch from the huge range available can be daunting but if you would like some advice choosing a torch, batteries, charger etc., there are some very experienced and knowledgeable people here who I'm sure would be happy to help you. Just post the type of torch you are looking for... price range, flood (wide beam) or throw (narrow long distance) and any other criteria important to you.

    18650 cells are better but you have more chance of receiving AAs in the post, customs are for the most part rejecting shipments labelled with lithium batteries, i've had 2 shipments rejected recently, although sometimes they are stopping packages with no batteries so as usual it's down to luck
    Resistance is futile-give in to DX gadget craving!
    also a voluntary mod-be nice please!

    Dear ozOzo

    Thank you for your kind offer. Actually I would like to purchase a good LED flashlight using 1 pc AA Size Battery (B'cos AA Size is conveniently available in the market) Price maybe between USD10 to USD 20. Lux (Lm) specification, the more the merrier and able to zone in and out. Small and compact. Any good recommendation?
    Your buddy

    Lol, in fact I was generously offering someone else's services.

    I'm no flashlight specialist but I just know @gasbag11 is waiting in the wings, looking for someone to pass on all he knows about the subject. That shouldn't take too long but it probably will! ;)

    I'm only joking btw... GB really is the bloke to listen to. I'm sure he'll be along shortly.

    Lux and lumens are not the same thing. Lux is light intensity, how brightly something is lit. Lumens are the total amount of light a torch makes.

    LOL. Once again ozOzo has over-rated my knowledge of flashlights.

    Unfortunately I don't have many suggestions for the type of light you're looking for. There just aren't any 1XAA zoom lights that are high quality in your price range, or any price range that I'm aware of.

    There are some high quality 1XAA lights, but none of them are zoom lights. They're also usually more expensive too. I don't think any of the big name manufacturers make zoom lights at all.

    You can look through sheepish's link, or search "sipik" for lower priced lights that seem to be very popular. You'll have to check the reviews to see which are the highest rated/most popular.

    Be aware that some lights use AA and/or 14500 batteries. 14500 cells are the same size as AAs, but they're much higher voltage and need special chargers. Any light that uses both types of cells will usually not be as bright with a standard AA cell.

    Feel free to ask, if you have more questions, and good luck in your search. :)

    NO! I don't know why DX screwed up the site so badly.
    Ask them.
