In search of..... 'D' lithiums (non-rechargeables)

[Canuckle]

Hi All,

I am desperately seeking 'D' lithiums, the non-rechargeable kind. Just about any make will do . . . Eveready, Duracell . . . the trouble is, I can't find any at all.
I am in Singapore, but international responses are welcomed as there don't seem to be any on this island. [img]/ubbthreads/images/graemlins/frown.gif[/img]

Thanks.

Try www.batterystation.com which has some listed. Also, digi-key.com has some.

Not sure if it's the kind you want but HDS has saft LO series D cells; these are the 3V high drain ones, not the 3.6V low drain ones...

Actually they are available locally from Farnell Components and most probably RS Components. If I remembered correctly, Farnell has the 3.6V one but cost S$40+/pc.

Just curious, why do you want to buy Li D cell when they are so expensive?

Hi reefphilic,

Are you new around here? Welcome to the group.

I've always thought that 'D' lithiums were much like 1.5v 'AA' lithiums - same size, same voltage as alkalines. Just different (chemistry) on the inside. This does not appear to be the case. [img]/ubbthreads/images/graemlins/frown.gif[/img]

Are 'D' lithiums rated at 3v, rather than the 1.5v that alkaline 'D' cells are? The dry chemistry of lithium cells is attractive as a leak-proof option for flashlights.

Thanks.

There are two common types of non-rechargeable lithium battery chemistry, 3.6 volt (seen in low current computer memory batteries) and 3.0 volt (seen in batteries like 123A and 2032). The 1.7 volt chemistry in the Energizer L91's is an uncommon type and right now is only available in AA cells. AAA cells with it have been announced for later this year but I don't think we'll see D cells of that type anytime soon.

19,000 mAH 3.6V, http://www.tadiran.com/prodpdf/viewp...et=TL-5930.pdf

Then there are their higher discharge variety: http://www.tadiran.com/plusesplus.php


Greater energy density...Tadiran Lithium Thionyl Chloride batteries offer the highest energy density of any primary cell: up to 710 Wh/Kg and 1420 Wh/I.
Higher capacity...Tadiran cells feature the highest capacity by weight and volume compared to any known battery technology.
Extended temperature range... Tadiran batteries can operate in temperatures ranging from -55°C to +150°C. However, to maximize the capacity, standard cylindrical wafer type cells are rated to a maximum temperature of +85°C. Special high temperature cells are also available.
Higher operating voltage...Tadiran Lithium Thionyl Chloride cells have an open circuit voltage of 3.67V and an operating voltage of up to 3.6V, a considerably higher voltage than almost any other primary cell.
Longer life...Tadiran batteries feature an outstanding shelf life and long term reliability. Over a ten-year period, Li/SOCl2 batteries stored at room temperature lose less than 10% of their total capacity.
Patented safety features...Tadiran Lithium Thionyl Chloride cells offer unmatched safety due to their unique "failsafe" construction.
Environmentally friendly...Our batteries are free of heavy metals, making them among the most environmentally friendly of all batteries.
#1 choice for Lithium

Hi thanks,

Actually I had been loitering around this board when high power LEDs from Luxeon is still a distant dream. I didn't register until some times later and also seldom post so nobody notice me.

Personally, I think the 3V or 3.6V Li chemistry is actually an advantage in that the number of cell can be reduced by half. Plus the other pros like high capacity, light weight and long shelf life. The only disadvantage is the HIGH price. In fact, I'm going to order some 3.6V AA battary so that I can have the same brightness of a 2XAA maglite with MM+ Lux3W in a miniminimag size.
