Duracell 2650's VS Duraloops?

[aab]

I recently bought many Duraloops that were less than half price and am selling some of my old 2300 and 2500 mah Duracells on ebay. I have 8 Duracell 2650's which I'm not sure if I should keep or sell and replace with more Duraloops.

Virtually all my devices are things where even the older rechargeable duracells would last about 6 months. The only event I can consider where the 2650's may be better would be if I intend on using my digital camera intensely over a short period of time which so far has never happened.

Over how little time would the 2650's start having an advantage? Over a 2 week vacation used in my camera would the Duraloops still be better? Even then I could simply bring 2 sets of Duraloops (my camera always has a backup set of batteries anyway) which would most likely last more than long enough plus I could bring my charger.

Another question, does anyone know if you freshly charge 2650's and Duraloops, after about how much time will the remaining capacity of both batteries be the same? This could help me decide if I want to keep the 2650's and would be good to know.

So should I sell all my non-LSD cells and get only Duraloops? It really seems like the 2650's have no possible advantage for me. What would you recommend?

Thanks

1)what camera do you use
2)what charger are you using
3)how often do you charge batteries
4)how does your camera run on the 2650s?
this will determine if there is advantages to using duraloops over high capacity nimh cells. Duraloops have superior voltage output, lower self discharge and are generally more robust but have less capacity. If charged before usage and used perhaps in a few days of charging (and not suffering fast discharge problems) the 2650s may have close to 25% more capacity than the duraloops per charge and with 2 sets it is like having an extra half set of batteries if the camera is ok with them that is.

1) Canon Powershot A630
2) Energizer Family charger (the new model with LCD screen)
3) When I was using non LSD batteries I would charge them every 2-6 months
4) My camera can record video non stop with the color LCD screen on for 3-4 hours or more on Duracell 2650s

In many years the only time I got a low battery warning in my camera was when I had forgotten to charge its 2650's for probably 6-8 months. I normally try to remember to swap & charge the camera batteries every 2 months or so but often forget and can go many more months on the same 2650's.

sound like the 2650s are working find for the most part no sense in going to LSD cells IMO as the main advantage is self discharge and higher voltage which won't make up for runtime of the 2650s unless they are allowed to self discharge long enough.

I already got LSDs for my camera, don't they make more sense since I use the camera only very rarely and for only a few minutes? I use the camera for probably less than 10 minutes per month, the 2650 batteries lost more charge through self-discharge than actual use of the camera.

I used to have an A620 until I dropped it down a mountain and broke it:mecry:

I would leave a set of Eneloops in it for six months or more and they never ran down. In fact I usually removed them for recharging before the low battery warning came on. Those A600 series cameras are real battery misers.

 

[aab]

Sorry, but what's "misers"? I find batteries last infinately in my A630, by very far the camera with the longest battery life I ever had, and my last 2 cameras used lithium ion proprietary batteries and lasted nowhere nearas long as my A630 with Duracell 2650s or Duraloops.

keep the LSD cells as backup for it, that way you don't have to charge your backup cells often and when you go out charge the 2650s up full and have the best of both worlds.

As I said in probably the last 5 years I've always used my camera in a way where LSDs would have been a much better option, I have no doubt my Duracell 2650's loose more power by self discharge when not using the camera than from using the camera since I use it very rarely maybe like to take 2-3 photos to sell something on ebay every few months.

So wouldn't it make more sense to sell all my Duracell 2650's and replace them with Duraloops? This would also prevent me from having to remember to top off non LSD cells every month or so.

I've also read about others on here replacing all their batteries with LSDs.

 

[Lynx_Arc]

I would say so, the main advantage of LSD cells is not having to charge them when not in use before usage. The disadvange of high capacity cells 2400 and up is they can self discharge very fast leaving you charging them before use otherwise suffering from considerably less capacity than similar LSD cells. People are switching to LSD cells for two reasons: 1)not having to charge them all the time just to use them (power outages is a bummer if your nimh cells are half dead from self discharge). 2)higher voltage from the start than non LSD cells. this can help some devices operate better that are voltage sensitive. It won't replace alkalines in some cases but people have reported in many cases cameras work better that would only give a few pictures on a full charge with normal nimh.

I hadn't heard about LSDs having higher voltage. How exactly does this work? Is it only the initial voltage that's higher or is it higher than regular NiMH for the entire discharge?

I just tested an old 2650 I charged several days ago and they were at 1.42 volts, I then tested new Duracell Precharged I bought recently and charged a few days ago also and it was at 1.39 volts.

Is this because the 2650 has many cycles on it and the Precharged is new?

 

[WildChild]

I just trashed a bunch of Duracell 2650. They have been sitting for the past two years charged and unused. They developped a really high internal resistance. The new Maha C9000 I just got can't do anything on them. Even with the discharge mode at 100 mA, the "Done" indicator appears right at the beginning of the charging process. HIGH appears on the other modes. The only one that works shows a load voltage of under 1V. I'm glad I just purchased a bunch of Duraloop on sale!

Eneloop LSD's using a good charger can charge up to 1.5 volts. They will show more voltage over time than non LSD cells, like 2+ months stored.

and higher voltage during discharge under load

If the 'Impedance Check Voltage' was ~2.10VDC, you 'might' have been able to nurse them back to 'Chargeable on the C9000' after several 'Deep Discharges'. Otherwise, you might have still gotten a few years out of them in remotes, clocks, thermometers, etc... with another charger. :thinking:

Another user reportedly lost 200+ (neglected?) Powerex 2700mAh AAs (in another thread)...

 

[WildChild]

My other charger (Sanyo NC-MQH01U) also refuses to charge them unless I drain them completely with my D10 and I put them on the charger while they are still warm. I'll try to cycle them a few times and if it's not better they will go to trash.

This is where the DUMB Chargers shine!

So, what's their ICV?

Unfortunately the rule with NiMH cells is "use them or lose them". We are all hoping this is less true with the LSD cells like Eneloops, but even those cells will perform best if regularly cycled.
