Maha PowerEx makes the best D rechargeable on the planet

most others are garbage or good fakes with far lower mah than they state.
It would be nice if you let us know what testing led you to this conclusion. I've thoroughly tested most of the D cells on the market and they all have about the same capacity no matter what rating is on the battery. The big difference is in each cells ability to maintain voltage under a load. So far none have done better than the Tenergy cells in my testing.
I have not tested the Maha D cells as I was told they put their name on Tenergy cells. I do not know this to be fact.
Avoid the AccuEvolution D cells at all cost. The old cells were great, the cells they presently sell are the worst D rechargeable cells I have tested and I've tested a bunch.
The Imedion D cells are not much better.
That leaves us with Tenergy cells which are surprisingly good for the price. Check out all-battery.com for the Premium D cells. They are actually better at holding voltage under load than the original AccuEvolution D cells which were awesome cells.
Avoid the Titanium D cells, while I haven't tested the D cells their C cells are the worst I've tested which leads me to believe their D cells would be poor as well.
Same question, I'm curious too about the "Centura Low Self Discharge"
This helps loads, or at least an opinion. Do you have any data or just anecdotal info? Experience is all I have. My testing has only recently become somewhat useful. All my prior experience/data is how things held up under use.
The Tenergy 5000 D's that I thought were lousy were NiCads. I use these in the same product (18W dive light) for ~an hour, and recharge them with the a high end hobby charger or a 1/10C wall wart depending on the pack and the time I want to spend.
Been doing this for more than 12 years, hobby chargers with some basic data I can use are relatively new. Only the Tenergy 5000 NiCads essentially croaked after about 2 years and maybe 20-25 cycles. Just wouldn't hold charge or capacity. Pretty poor.
You apparently think the Tenergy NiMh (these?) are about the best you've seen so far?
Any input on the Tenergy 10107 LSD D Centura 8000 mAh 2-Pack Blister Card ($15.95 right now).
With the poor taste of the Tenergy NiCads remaining I need a little reassurance on the product before venturing into that brand again.
I suspect there must be some kind of capacity inflation vs actual performance going on by marketing like in AA. I've found AA > 2500 to be mostly worthless. Maybe the same thing in D's > what 10,000? The Titanium 12000 certainly are NOT.
I run the Tenergy Centura 8,000 in my TK70 and have been happy as well. I have only had the light for a short time so i cannot attest to their LSD properties, but i can say that i get close to an hour on turbo :thumbsup:

How long does the TK70 run on turbo exactly? On the TK70 thread a user gets an hour on turbo with the Imedion D cells. They might be LSD but that's interesting you get about an hour too on the 8000 mah Tenergys.
