mixing duraloops & eneloops

[jcs71]

Hi there. I have a couple of questions.

Would it be ok if a person mixed Duraloops and Eneloops in the same light if they had to?

I know the golden rule of never mixing brands but wouldn't these be an exception?

Thank you.

They may be different "brands" but they are the same battery essentially just different batches. The only issue I would have mixing duraloops and eneloops would be capacity as sometimes batches vary and if you have a light that would work down below ~1.2v then the weaker (less capacity) battery would have a chance of reversing possibly ruining it otherwise it shouldn't be an issue.

Mixing batteries is never recommended.

Personally, I try not to mix even different badges (but one has to if one need lots of batteries).

Mixing different brands is totally out of the question.

"If they HAD to" sure. But I wouldn't do it just because you're lazy. I don't think it would be that big of a deal especially if the batteries are fully charged first, and, you don't fully discharge them.

But, as others have said I don't like to mix different battery batches. Doesn't mean I don't though....
(I've been known to use 2007 Duraloops with 2009 Duraloops, but I checked their capacity first)

The worst that would/could happen, is that one of your batteries would get reverse charged and most likely ruined. It's not going to blow up or anything like that.

x2... I dont think theres any immediate harm or danger. It could set precedence for lazy habits to develop though. If you were to accidentally mix a Chinese black-top cell with a legit Japanese white top duraloop... that could be trouble.

I will be using six AAA LSD cells to power a modified 2C Maglite ... Since all my AAAs are either 800mAh or 820mAh , I will probably use two different makes ... I will be using two 3AAA cassettes that come in those cheapie 3AAA torches ... The light output will be well over 400 lumens , possibly near to 600 lumens ... I will have for example one cassette with Eneloops in and the other with either Hybrios or GP Recykos.

I might eventually have to get a few more of one make , though I do have six of the GPs ... I probably do have some more of the Eneloops if I open up some of my remote controls.

We will have to wait and see how it turns out ... The Mag 2C will also be used with two 18500 Li-Ions or 2 AAs or one 18650 or even two C cells.

The dropin will allow up to 9 Volts to be used ... It has 36 LEDs in a shower-head design.

I think the bigger problem would be mixing the chinese and japanese as they probably differ in the internal resistance which would make one discharge faster than the other when paired together so even if the capacities were identical the discharge rate could differ to the point of one being depleted faster than the other increasing the chance of reversal in some devices even more.

If you have two batteries of identical mAh capacity but with different internal resistances , I assume that the one with the higher resistance will warm up more than the one with the lower resistance under load conditions.

The batteries should (more or less) discharge at the same rate under load conditions ... As far as I can see , the only real difference is that one battery would possibly heat up more than the other ... This is assuming that the chemistries of the two batteries is identical ... With different chemistries , the discharge curves would be different and one battery could discharge quicker than the other.

The heating effect could also affect the battery capacity and also increase the self-discharge of the cell.

I try not to use different makes of cells even though the capacities are the same but when I use six AAA cells , I might not have six of the same make available at the time ... So , I would use two sets of three cells in the 3AAA to C adaptors.

I don't see any problem as long as (in my case) the cells are all 800mAh LSD NiMh of proven reliability.
