I’ve had good results from a year+ hard use of the C-Centura LSD.
I had lousy results from the blue 10K, but they were an eBay deal and may have been stored/abused. They lasted 2-3 years and performed poorly with lousy retention. OK if used immediately after filling.
Yeah, back when they were widely available on eBay I bought some of the Tenergy LSD cells
— light blue with a lower case letter “e” on the side. They were on deep discount in large batches.
(At the time they were discontinued, no longer for sale on Tenergy’s site, replaced by the white ones now available)
They were, most of them, terrible — lost capacity fast on the shelf. Maybe one in eight or ten was good.
I read somewhere later that a lot of them had been in outdoor metal shipping box storage that sat too long in the heat.
Well, I have both LSD D cells from Tenergy and Imedion to power my Fenix TK70 modded by saablaster.
It’s been quiet a long while since I have refreshed them but when I will have time in the near future I will take a discharge test in my iCharger and get a Logview graph of its discharge performance, perhaps at 7amps, though from simple discharge tests I have done when I initially got the Imedions and 15 months of so thereafter, I remember I am not happy with its capacity retention. Both cells have undergone break-in
and eventual refresh processes in both iCharger and Maha C9000 using adaptors.
Just the better performing ones
I actually just checked Amazon again and found a four pack of Everactive’s for about $24. I did not find EBL’s. I guess part of the question is that I don’t know if this is a great, good, or bad price. Since I’ve never bought them before I have no comparison.
I also need to run a test to see if my Coleman lantern will run at 4.8 volts rather than the 6v of fresh alkaleaks.
My Coleman lantern worked fine on NiMH but produced slightly less light. The main problem was with NiCad cells they’d always be dead when I needed the lantern. (It was designed, of course, for alkalines, which was expensive in use.)
The lantern in question is a Coleman CPX-6. I won it in an office Christmas gift raffle. I have the 4 D-cell battery box, I hear the rechargeable one they sell is ni-cad and I have no intention of going back to 1980’s battery tech.
My RD-tech supply indicates that it runs at 0.28 amps at 6 volts, it only drops to 0.26 amps at 4 volts.
Curiously, running the supply up to 8.4 volts does not increase the current, still only 0.28 amps. I actually have a broken battery box, I may try putting a couple Lithium cells in there.
