Test results for D size NiMh Batteries

Due to popular demand, I have added test results for a variety of D size NiMh batteries at: http://www.torchythebatteryboy.com/p/nimh-d-size-batteries.html

Interesting. Could you alao do at 1A or even 2A-3A-5A ? 

Would be nice to see how they hold up

Thanks for the info on D-cells, not easy to come by. Checked out the rest of your site. As a diver I appreciated the review of dive torches. Do you take these on test dives? Obviously UW reliability is a critical feature.

Have you tried any of the LSD NiMH D cells? I have some Powerex Imedion that I use in a 2D MagLite (my Dad’s actually, trying to presever the ol light and protect it from Alkaleaks)

I used to send samples to a guinea pig who tried them out and sent photos of the beam shots under water, but the feedback dried up.

I haven’t tried LSD, but I can add them

Not even in the sixties? Big Smile

It was your battery information that LED me on the search for quality cells and lights and I eventually found this place, thanks, you’ve cost me a packet Wink

Thanks torchy. Its nice to know that some of these can still approach 10k mAh.

I’m just checking and some of these are supposed to be low self discharge. What I noticed with AA batteries is that some of the supposed low self discharge ones went flat a bit quick. I only noticed because I had some charged up and about a week later went to use them in my mouse and keyboard. I was thinking of doing a table to see how much the voltage drops over a given period, maybe a week or a month.

Just pulled my 4 Imedion D cells from 2 MagLites, haven’t charged them in at least 6 months. They were used a few times here and there and were still holding pretty well. They’ve now been conditioned and recharged…

MAHA Imedion’s are in my opinion one of the higher quality Low Self Discharge cells available, I use a lot of them in AA for my flash units, best ones I could find in the D size but don’t start thinking they’re cheap because they’re not!

Good info for those of us who still like “D” cells Wink

Nice!

If you ever get the chance, try the Ultrafire DV-S9? 26650, triple O-rings at the tail, magnetic slider for moonlight-to-turbo. Quite nice for ~15bux(US).

https://www.fasttech.com/p/6550300 (BLF discount applies! Big Smile )

Wondered why the huge discrepancy in NiMH D cells. I know the Rat Shack ones were essentially NiMH AA cells but mounted in a D-sized shell (ie, same capacity for AA and D!), but wondered if I could assume something similar for the D cells you mentioned.

2AH to 10AH is a huge difference!

THe 2500mAh or so D cells tend to be very light.It never crossed my mind that they may be a shell with an AA inside. I’ll need to look into that, literally.

Long time ago I had some Radio Shack NiCad D’s – 4400mA. Used them for diving in a 4xD light (18W) almost every weekend for probably 8 years. Then got some 8x Radio Shack 4500mA NiMh. These have a 2002 date on them. They got used the same way for ~ 10 years. I still have them and use them in emergency lanterns. At last capacity test they came close to spec, ~4300mA. Hefty batteries, reliable as hell. I’ve had a number of different D’s during that period, but none that could do the weekly long haul like these. They sure as hell are not AA in a D-shell. Maybe they changed them later, but these were excellent.

I’ve read, but not tested, that D-Eneloops are shells.

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.

That’s what I use. I have the blue ones. I think these were top dog like 7 years ago. Then the white ones came out which I think were a bit better.

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.
