I wouldn't buy those Duracells... The high self discharge rate of normal NiMH cells is far greater than Eneloops, therefore in long term usage, the Eneloops are way better.
ILF, if you bought 16 cells, you could do the test. Charge all of them, split in two groups, do the runtime test of first group immediately after charging and leave the second group for one month on the shelf. Then after one month do the runtime test of this second group. This will give you an idea, why Eneloops (and other LSD cells) are so popular and highly regarded (despite lower capacity rating on the box).
i was patiently waiting when you would give in and get a tk41.:)
would like to see it compared against your other throwers like the m3x and 7g5 though it would most likely end up behind those two. still i love my tk41 for the use of AA's.
I have had mine for about 8 months, and I have only changed out the batteries twice. Sucker runs a LONG time if you don't always have it in Turbo mode.
No Ilike, I didn't win, you won. While not quite as good at throwing as the M3X, it's close enough that you will not notice the difference in actual use. The extra spill, extra modes, tailstand ability, battery life and lower cost/longer battery life overall of this light will probably move it to the top of your list. It's just easy to use and even the lowest mode of 10 lumens will really throw a beam a long way. Build quality and finish are excellent. I know it doesn't come with a holster but I think the Jog Strap would fit the bill. LOL
I have some Duracell 2450 batteries and they run longer than my eneloops. They are good batteries. I don't think they will recharge as many times as eneloops or stay charged on the shelf but they will work just fine for you. You did notice that the picture of the Duracell batteries you ordered were not the same didn't you? Two of them are 2450mAh and two packs are low shelf discharge. I don't know which ones you are going to get but you will probably want to keep the same batteries in your light and not mix them.
Anyway, congratulations on your new TK41. It good to know you finally saw the light. (No pun intended) When do you get it?
Yea I see what you mean on the batteries. Oh well I 'll use the lower shelf discharge in my camera and other devices. I did bid on 8 more of the 2450mah ones.
If you have a Costco near you or know anyone who does and has a membership, have them pick you up a 10 pack of eneloops. They are $19-$20 for 10 AA 2000mAh batteries. I have lots of AA NiMh batteries but I'm picking up an extra 10 pack or two of eneloops just to stash away for hard times. They last a long time. They won't hold as many mAh as Duracell or Powerex but they recharge 1500 times and they have low shelf discharge rate. They hold 75% of their charge after 3 years on the shelf. That pretty darn good in my book and worth having a few around just for that reason.
BTW: Don't be surprised if your new TK41 becomes your best and most used larger flashlight. It's a real joy to have on hand. You got a great price. Was that price including shipping?
