Help Support Candle Power Flashlight Forum
🙂Yeah, but was David speaking for himself or for Fenix?
I'd be interested to find out the sales numbers for the tk40.
If the sales numbers are good or better ... then it does not support the suggestion that Fenix will not go down the 8xaa path again.
Heck, I bought the tk40 for that reason! I have lots of eneloops ready.
I am very glad to see that they recognized that multi-AAs in high-drain applications really wasn't the wisest decision. Kudos to them!here's the post
"single aa? not possible.
mult-aa's? no way. We're getting tons of returns on the fenix tk40 from
1) reverse charging and leaking from unbalanced cells
2) people putting cells backwards and cells rupturing and leaking from the light being OFF. yeah, they turn as hot as grenades when you have lithium aa's put in them backwards
We're dealing with a lot of angry people all because of AA's. It's not really the AA's fault. It's the design. AA's were NEVER designed to sustain such high power loads. Perhaps nimh's will do ok, but even then, theres a thinner line between charged and discharged when you're talking about 1.25v cells.
KABOOM. Lightning-y.
Nope, we ain't going there."
...it looks like they were talking about 7777.
they really should start making most flashlights that can lego different battery tubes so everyone can get what they want.
i like the 8 AA configuration in the TK40 myself.

Speaking for myself and 4Sevens. 😀Yeah, but was David speaking for himself or for Fenix?
I thought you weren't supposed to put lithium batts in the TK40, doesn't that void the warranty? I was under the impression that it was rechargeable AA's only and AA alkaline in an emergency...:shrug:
Fenix did warned in their manual about different battery types and with different voltages, even operation with 4AAs, hence to the leaking. And they did not recommend 1.5v lithiums for several technical reasons. The TK40 4x2 AA configuration is unique and I don't have any problems with it, I liked why they use AA very much. But what I recognize is that not every user have sufficient knowledge regarding battery chemistries and voltage, safety and operation. And not everyone reads the manual to find out what those warning means. Because of this, Fenix perhaps should have thought about the majority of users when they designed the 8xAA light. But I wonder, was it really a design issue? Or ignorance.
But hey, this is TK30 thread, I'm sure in their marketing research, development and feedback from their TK40, I don't think it's gonna be another 8xAA light. But I don't mind if it's 2x18650/4xCR123 and 8xAA capable with special battery holder! Nah, maybe too much.
Hi, I was just assuming about the TK30's that we're excited about 🙂Which will require the special battery holder?

so with the extention, it would be a 4 lithium cell light? sounds cool, kinda like the M3L surefire is coming out with.was told I can hope for:
- basic 2xCR123A/1x18650 body
- extension tube to accomodate 2x18650
- MC-E
some official announcement may be coming next month...
I hope they will do something about the model name, as TK30 has the potential to get mix-up with TA30, as the later are most often mistakenly referred to as 'TK30'... :thinking:

It was quietly updated after a few "incidences" that we reported to the manufacturer. We weren't told the exact reasoning, neither were we notified of the changes in the manual.You obvious got another manual than I got, in my manual there are no warnings about battery, only a recommendation to use high quality batteries and they only mention 1.5 volt batteries and recommend alkaline and NiMH, but they do not warn against any batteries.
Could you copy the warnings and technical reasons against lithium from the manual? I would expect lithium to be nearly perfect for the light, only problem is the price of the battery.

I'll have someone do it next week. 🙂You are making my really curious, could you mail me a scan of the new manual?
