Wow, food for thought. I have bunch of the old blue 10440’s . I use them all the time in applications
that were never intended to get such a kick in the A—…-. Does the same apply to 14500’s , in general terms?
I saw the bottom of kreisler’s post.
“UltraFire Gray Protected red marked cell 254mAh-0.1A (repeated tests: 261mAh, 260mAh), or: typical if not charged fully to 4.200V: 245mAh) UltraFire Gray Protected *unmarked cell* 225mAh–0.1A, rest offline voltage 3.3V (repeated test: 229mAh)”
What is does it mean by red marked cell and unmarked cell?
There are 2 more options for protected 10440 which might get popular.
Hope there will be reviews for the batteries soon somewhere.
They could be identical or clones of those mentioned in the OP.
The protruding nub of the ultrafire one looks different as it looks smooth in the third picture on the site.
I have never tried 10440’s as of yet. While I was buying a couple of AAA Balder TD-0 I decided, what the hell, and grabbed a couple of cheap ultrafire 10440.(not a brand I would normally buy). As its taken so long for the lights to be shipped, I’ve since ordered a couple of AW ICR’s and an IMR, so I guess I’ll be exploring the world of 10440. I already own a UltraFire WF-138B (10440/14500) charger with a max charge rate of 250 mAh, so I guess I’m good to go.
