Hello. Buying a lantern at 40% off and it runs on (3) D cells. I would like to get some adapters and run it off my expanding supply of AA Ni-MH. Anyone presently doing this? If so, what is a good brand. Also, how much is the runtime reduced. Appreciate any input here. Thanks.
thanks Cone. This lantern runs on 3 D cells. Do you know if it is ok to put 2 AA's in each D cell adapter, the total would therefore be 6 aa's. Is that too much voltage for the lantern? Someone said the voltage would not increase???
thanks Benckie. Do the adapters work well. I have heard some don't make contact? Do you use the adapter in a flashlight? Soshine is a good brand I believe.
They are OK for the price and do work i use them with AA energizers 2450 mAh. I can see the clip's on the side that hold the positive top down breaking after a bit of use, but sofar so good and for the price they are cheap enough.
The voltage with 2 x AA's is the same as one as they are in parallel so it doubles the run time out of the AA's and shares the load over 2 x AA's per adapter.
So if you use 3 adapters with with 6 envelope's the voltage would be the same as 3 x D cell's.
I find it easier to use the rechargeable D cell's i linked as its hard to find 8 spare AA's in my house as they are always being used for some thing.
I said the voltage would be the same i did not mention mAh.
Since you mentioned it here we go as an example, if you brought the 2 x AA to D cell adapters, like i linked and used 2000 mAh envelops and used 4 of the adapters in series in a fenix TK60 or TK70 you would get a 6 volt 4000 mAh battery.
In parallel it would be 1 x 1.5 volt 12000 mAh battery
In series it would be 1 x 6 volt 4000 mAh battery
As a guess your lantern would be wired in series so you would get 4.5 volt 4000 mAh battery
In series you add the voltage together the mAh stays the same.
(e.g 2 x 2000 mAh AA,s is 3 volt 2000 mAh fully charged)
In parallel you add up all the mAh but the voltage stays the say
(e.g 2 x 2000 mAh AA,s is 1.5 volt 4000 mAh fully charged)
