Quick battery question

[Zatoichi]

After reading around here, I noticed how popular Eneloop batteries are so I went looking for some in town today. I couldn't find any, but I got some GP 2050's. I've noticed that sometimes certain types of batteries aren't recommended for certain torches. The ones I'm wanting to use these in are my Nitecore D10 and my Olight T-25. Will this be good/bad/okay?

Cheers

The Olight website (Olightworld.com) rates the working voltage for the T-25 as a range from 1.1V to 4.2V. Should be fine for that light.

when someone types "Eneloop", better think that refers to "eneloop-kind",
there is quite a bunch of "precharged" Ni-Mhs already, they all feature that low-discharge technology.

f.e. at AA I have Uniross Hybrio as well as Eneloops, they all are more or less identical.
with AAAs I have just have Eneloops
... all work very well.

During this year, I have recycled quite a number of my classical "much higher number printed on and therefore better" Ni-Mhs and the very few remaining ones now perform worse than the precharged ones.

This is about batteries rather than the lights in which they are to be used, so I'm moving it to the Batteries section.

Thanks DM51, I'm still finding my way round. :thinking:

Thanks for the replies. I put them in the Olight and they are indeed fine. I'll be getting another pack.

You might try a runtime test to see if they are worth it or not.

 

[Zatoichi]

I'm personally convinced they're worth it. Some of my torches will go long periods without being used, and the thought of batteries dying in them bothers me, so that alone justifies the cost. I expect decent runtime too from what I've read, but I'm not yet 'dedicated' enough to measure it myself.

That's got me thinking - despite being bothered by batteries slowly discharging, I can't bring myself to lock out the batteries (where that's an option) on any of my torches. This may be because I'm subconciously aware that at any time, any one of them could be the one I urgently need... Is this a bad sign? :eeksign:

Another quick noob question, rather than starting a new thread. Given that all (lsd ni-mh) brands are pretty much the same, is there any problem with charging eneloops in my recyko charger? I don't see why there would be, but better to ask. And one more quicky, I have a fairly old (though little used) Uniross charger which originally came with 1300 mah ni-mh's. Would that be okay for eneloops and recyko's? I don't mind if it just takes longer, as I prefer that to buying another charger.

Cheers.

LSD (Low Self-Discharge) batteries are basically NiMH -
so almost any NiMH charger should be OK -
but like all things in life - some chargers are just better than others.

The GP ReCyko seems like a pretty good LSD - SilverFox's Eneloop Self Discharge study shows them to be strong batteries. They did very well in self-discharge tests over at dpReview.com.

I speculate/suspect (note my caveat) the Kodak Pre-Charged might be re-badge of the GP ReCyko - as the two curves in the self-discharge tests were so similar/overlapping, and I think the Kodak Pre-Charged are very good LSD batteries.

The charger is half the equation when dealing with Nimh.

To answer your question first though, any Nimh charger will work just the same for the eneloops, or any Nimh battery.

So, moving on, what you ideally need is a "independent channel charger". This doesn't have to be expensive, it just means a charger that will charge each slot according to what the battery in it needs, and it will stop charging when that battery is full. This much better than timed chargers, or even worse, chargers that just keep going until you unplug it.

I see your location is the UK.

Super-Fast, Smart charger for AA & AAA Batteries £11.99

...and if possible, get that. I looked into it a while back, (and got one) and it turned out to be a rebrand of a well known and popular Titanium brand charger that is sold in the USA and elsewhere. It has a small LCD display and will show bars moving up while the battery charges, just like a mobile phone, then they'll stop when the that battery/slot is ready and you can take it out.

Having that sort of charger is priceless, and certainly worth the £11.99 if you feel like a Christmas treat

Cheers, that's great. I read the article and it does look like my other charger will suffice.
