These batteries are just the same as the Sanyo Eneloop AA batteries. If anyone doesn't know what Eneloops are , they are batteries that unlike other rechargeables keep their charge for months , staying ready to use. I use them and they are like night and day compared to other rechargeables. Panasonic bought out Sanyo's battery division so these are Sanyo batterys with the Panasonic name on them. Sanyo Eneloop 4 packs are £7.50 ish so at £4.75 delivered they are a steal.

cheers bought a pack hot from me.

Hot!

by 'night and day' I mean these batteries last a lot longer than other rechargeables and unlike other batteries you can put them in a drawer and 6 months later take them out and use them as they have kept their charge. I have lost count of the AA rechargeables I have thrown away as othersI have charged and tried to use a few months later have been dead after sitting in a drawer.

The big money is in selling electric car batteries, which probably means these are 'showcase technology'.

BTW - price is low enough to be a fake.

Lol , I see your point whatsthepoint, I geuss I like to be prepared and have a few batteries sat there just in case, but don't want ones that I am just going to throw away after 1 use. So I am prepared AND tight!

bought! reminded me I needed some of these!

Cheers op...stolen 2

very good batteries can vouch for them...one charge lasts for ages

How do these compare to the vapex batteries?

How many moths? sorry couldn't resist, great info thanks

As above table from candlepowerforums suggests Vapex are fine. I've used them for years and have the "instant" power types too without any issues. Don't forget you need a good charger to put a good charge in your cells! One with independent channels and dV and dT sensing. I have some of these too HOT deal.

-dV/dT

"As a Ni-Cad battery nears end of charge the voltage rises faster that it did for most of the charge then peaks (the slope is zero) then falls off with increasing negative slope. By looking for the negative slope the charge can be terminated very close to the 100% of charge point. This does not work for a C/10 charge but need some higher rate.

A similar effect is present on Ni-MH cells but the size of the peak is much smaller. So a charger made for Ni-Cads that uses -dV/dt termination will not properly detect end of charge on a Ni-MH cell.

As of Dec 2007 both Sanyo and Duracell (the only ones I've checked recently) do not recomend -dV/dt as a charge termination method for Ni-MH."

"dT/dt versus -dV/dt

These two termination methods work well for NiCads, and are both applied to NiMH as well. dT/dt measures the temperature rise at the end of charge. After the battery is fully charged it starts new chemical reactions in order to absorb the unneeded current. In nickel hydroxide style batteries this consists in generating and recombining oxygen. This process heats the battery. The sudden increase in temperature rise can be used to terminate the charge.

Another effect of the oxygen generation/recombination cycle is to depress the voltage of the battery slightly. If you can detect this voltage depression you can use this signal to terminate the charge. Of course, -dV/dt is the easiest because it doesn't require a temperature sensor. The best method for NiMH is the dT/dt method. There are two main reasons. With the NiMH battery the voltage depression is smaller, and harder to detect than with the NiCad battery. This almost always ensures an overcharge, which will limit the total number of charge/discharge cycles before battery failure. Second, a new NiMH battery has false peaks early in the charge cycle, and so the charger will terminate too soon.

There are new algorithms that use microprocessor control to use the -dV signal to detect the end of charge. These can work very well and several of our chargers use this technique, which involves pulsing the charger on and off to do the voltage measurements. This technique seems to be sensitive to imbalance in the capacity of the cells. The dT/dt is still more reliable, especially for large packs, but in cases when only two wires are available solutions are now available."

Hot.

Heat added. Great job

heat for the product
beware of the claim re "delivered ready to use" though, bought 4 last week from the same seller, delivered on Sat, all 4 had approx. 20% charge at max and hence had to be charged first

[quote=whatsThePoint]so your saying these are great batteries for people who never use them [/quote

Have you really got nowt better to do? What IS the point?

Are these bigger than normal rechargeables size wise? I only ask as I have bought some batteries recently which won't fit in as they appear to be 1mm bigger than usual. Cheers

Why didn't you just recharge them, rather than throwing them away?

How do these compare to the vapex batteries?



From Vapextech's website:

Capacity Rated 2400mAh
6 months About 80% of charge is held
12 months About 70% of charge is held (normal nimh would be empty)


I have lots of Vapextech's AA Instant, and they are good. The batteries have 2500mAh printed on them, but the capacity varies between cells - about 2300 to 2700 according to my charger.

Bought some white Eneloops recently. The batteries are labelled 'Min. 1,900mAh'. I get 1900 to just over 2000 from the Eneloops. But the main benefit these have over the Vapextech is that it retains charge for much longer. From their website:

Up to 90% of charge remaining
after 1 year of storage

Up to 70% of charge remaining
after 5 years of storage


I mainly use the rechargeable batteries for my children's toys: Vapextech's for high drain devices (e.g Innotab tablet where it's used very often), and the Eneloops for toys which are not played with very often (e.g their digital camera).

I don't have the Panasonic Infiniums, but their specs:

2100mAh
The Infinium batteries keep 80% of their charge after 12 months without use


So I guess they're a cross between a Vapextech and Eneloop.

It's now £5.25

As noted, now expired. Seller of next cheapest (at 5.25) is ecotronics, who sell cheaper from their own website, although for the amounts involved you may want to stick with Amazon's front end.

When it comes to "Panasonic" and its "Infinium", either this standard bearer of Tojo Inc., The Robotic Tentacle of The Bookie, has been compromised by The Counterfeiters or that Stirring via Distration is the means to throwing its mermserised off Its true scent. Absolutely, expensively and mesmerisingly useless on the 4 sets bought from 2 diffferent places over a 5 month period. At best, no better than average and even worse than 7dayshop GoodToGo, which is middle-ish in prowess.

The way to control and then own the dual natured is to offer both its duality a voice and then you'll have Peter tusseling with Paul forever and a day via fairytales like "Democracy", "Communism", "The UN", "The EU" and so forth. When it comes to Truth, just because 99 patrons do not have a fly in their soup does not mean the one patron who does should be denied reality via "Democracy".

Every human is born to realise Self via self-mastery whereas to master or be mastered by another, oka Selfishness, realises/liberates only [the myth of] Duality, oka Relativity. All Supply & Demand, which includes "Government/Politics", needs to do to Control/Own, which latterly/latently is Abandonment, the MO of Humanity being Of Ownership Issue, is to favour one over the other and Truth will not only be unrealisable, then, Truth will neither have a Beginning nor an Ending, The Middling Truth being the mechansim for tethering the dual natured to their myths forever and a day. As such, Self-Mastery is the ONLY way for a human to realise his Self/Reality otherwise, he'll be Of Relativity from birth until death and should there be a non-material realm, Birth-Death then is merely a cycle, which, on the one hand is the WIP of Mercy & Compassion but on the other hand is Malevolence's way of preventing a human from realising what-why he was/is born for, Malevolence being merely another word for, "When Benevolence is Absent", and is not a reality. It is like, say, a cesspit, which when avoided, is but a myth then. Just like others' needs, which is caused by one's wants, becoming a myth/invisible because Propaganda is reigning, ALL being strung together like an infinite String of Pearls within the non-material realm.

All the likes of "Tojo Inc." need to do is to offer sub-standardness in some of their Fame, Fortune & Immortality below the radar and Bob's yer Banzai. When Duality is the Reality, The Currency cannot be Trust but Fairness, oka Conscience, or else The Middle Truth is all you'll ever realise. That is assuming one has the means to realise Conscience/Fairness. Not recognising/facing/realising that Humanity is Of Duality is the reason why there is zero solution to Humanity's Inhumanity other than imagining, wishing, hoping and praying that one's Want exists within its own airy-fairyness and is not the cause of denying others' Need. Not when Oxygen is a Truth, Truth being that which is applied to ALL and not merely to the privileged, special, glitzy, entitled, expectant, demanding and royal. Just like Birth and that inconveneint truth, Death. Especially when there is an Energy Creator whose only duty is to Give if only because He, through She, knows nothing else. You would if you could too. Create Energy. Seemingly/practically like The Sun.

And your recommendation for a VFM charger would be.......?

"So I guess they're a cross between a Vapextech and Eneloop."


Nope, more likely old stock, The newer Eneolops (Infinium brand in Japan?)) hold charge better and will do 1500 charge cycles.

The are not eneloops at all. The are not white around the positive nipple they are black. Eneloops are white there, as are the 2000mAh Duracell stay charged (Duraloops) and the Contours I posted earlier in this thread.

These Panasonics are not related to eneloops at all.

They test identical according to most sites. I'm not quite sure where making the plastic protection white comes into play.

I dont think they do test identical. And the Panasonics are rated at 2100mAh which eneloops never are.

Contours can be had for £4.50 for 4xAA or with a charger for £6.99, according to one of the flashlight forums they're eneloops.

Nope, Eneloop use a minimum rating so are in fact the same as other's 2100mah.

Thanks for your post in here. I've ordered one...
Sounds cool for me as I was looking for Battery Charger as well ? (_;)

I've read about these batteries online and it seems they are good for Cameras ?
Have you used them for heavy duty devices such as Camera or Shaver ?

Btw, Thanks again for your comment in here
