Looks the same as my £40 intelligent charger that gets recommended.

Great unit. Quick and easy usage is to put batteries in, insert power lead, wait a few seconds and click the mode button until TEST appears.

That gives you accurate battery capacity meter readings, taken from the one discharge cycle that occurs using Test mode.

Is this better than the Duracell charger which was posted in the last few days

I would never use that low end Duracell one, it looking 1000mah only.

The highest setting on this I use is the 500mah one, though it goes up to 1000.
The one item missing in this is Lithium capability.

Cheaper than what they are selling it for on their own website, and free postage too. Thanks OP.

Yes it is miles better.

This has 4 independent charging circuits, one per battery, which means it stops charging each cell when it is full and can charge 1 to 4 cells, I'm not certain, but I think the duracell one charges batteries in pairs.

You can select the charge rate 200, 500, 700 ma, or 1amp (it can even be set at different currents for individual cells if you wish to).

It shows the voltages of the batteries.

You can test batteries which fully charges them, then discharges them to measure their capacity before automatically recharging them again - useful for sorting a failing battery from a good set, and sorting old batteries into sets with similar capacities, and spotting if you've been sold batteries with exaggerated capacities..

It has also got a recovery mode that keeps charging and discharging the batteries until they reach their peak capacity, which has recovered some, or most of the lost capacity of a few of my failing cells.

ordered, cheers HOT!

Got one of these a year ago (ish) from this seller. Haven't used it loads, but does seem to test, charge, discharge and repair rechargeable batteries well.
When I first got it I went a bit made and went through all my batteries and was able to repair a few and throw a few away that proved to be duffers.
A handy thing to have.

I think he might be talking about the 15 minute one:
hotukdeals.com/dea…989

That pumps over 6A into a single battery, 3A when using multiple:
lygte-info.dk/rev…tml

They're aimed at different markets. The Duracell one is purely a quick charger with no other functionality while this is a more general use product with low enough charging rates not to impact battery lifespan and other functionality like monitoring and testing.

I bought one of these a couple of months ago, when they were posted here as a deal. It just died today. You plug it in, the display loads, then goes off and does nothing.

We did have one of the ones that this is a clone of, can't remember the brand. It went on for years and was great, except for the null battery bug. Finally that one became faulty and I bought this to replace it.

When it worked it was fine, but the build quality seems much poorer, the battery terminals, for example, appear much flimsier and poorly manufactured, and it just died after a couple of months and a few tens of uses. Might just be a fluke, but I can't recommend. I hope 7Day have a good support policy.

They claim to have a 2 year guarantee in the amazon questions, let us know how good or bad their support is. I've had mine for a couple of years and it has been fine so far.

Are you sure that's the right charger?



The amazon description seems a bit confused, and I wouldn't be too surprised if you get sent different Duracell chargers from different amazon sellers, but according to the product description it is a "Duracell Hi-Speed Advanced Battery Charger" which if I've got my sums right, would appear to be a 1.5 amp charger (not what I'd call a rapid charger, but fast enough to quickly deplete the capacity and life of nimh batteries).

Product Description

The Duracell Hi-Speed Advanced Battery Charger can charge 2 AA batteries in just 45 minutes (*Approx. 85% of full charge when using Duracell 1.300 mAh AA NiMH batteries). It gives you up to four hours of use in just 15 minutes of charging (**When charging AA batteries; results vary by device and usage pattern). Its 9 safety features make sure that you can keep going without any worries and after batteries are completely charged, the charger can automatically shut off to prevent from overheating. This charger comes with Duracell’s 10-year guarantee, so you can rely on Duracell’s long-lasting power every day.

That 6000 mah is the highest I have ever seen so the comment 'Conclusion,
This charger is not the right solution for long battery life, but it is very useful if you need batteries charged fast and dont mind replacing them frequently.As a general purpose charger I will not recommend it, but for people needing very fast charging it is useful, but as usual the announced charge time is rather optimistic*.' there is much an understatement.

Possibly not, it's always difficult to tell with Amazon and duracell.

If it's the CEF27 then the review is here:

It's a little more than 1.5A at peak speed but not much. That's not worth that sort of money if it is the 45 minute charger and not the 15 minute one.

Quite agree.

Hmm, if you click on the "buy now" link under the CEF27 picture on the Amazon Duracell charger page from that deal, it comes up with the same url as the current page, but if you click on "Buy Now" under the CEF15 picture it comes up with a dead amazon URL amazon.co.uk/dp/…5_t

So my guess is it is supposed to be the CEF27, although you might get either, or something else.


The CEF15 is probably worth the money to someone that really wants a rapid charger, I wouldn't want to put my LSD Eneloop batteries in it though. The CEF27 on the other hand seems to have little or nothing going for it apart from a long guarantee.
Edited by: "melted" 12th Aug

If rapid chargers are bad for rechargeable batteries how come electric vehicles are taking off in a big way, surely they wouldn't be a success if it took hours to charge your car battery cells at an outside charging point ?

Can anyone recommend some good AAAs to go with this?

Yes, that one's definitely the 45 minute charger. The 15 minute (CEF15) is roughly twice the price on Amazon here - amazon.co.uk/Dur…ger

This 7dayshop is a far better deal, rarely available this cheap, good spot op

You can't really compare them as it's totally different technology. Electric Vehicles use Lithium cells so would have more in common with your mobile phone.

Electric vehicles mostly use lithium ion batteries (often 3.6 volt 18650 Li-ion laptop batteries), which can be charged at higher current. This is for NiMH batteries, charging NiMH batteries involves a chemical reaction, if charged too rapidly heat and gas is produced that can escape the cell, decomposing the electrolyte. You can, or at least could buy NiMH cells specifically designed for rapid 15 minute chargers, but they were lowish capacity, expensive and still degraded by fast charging.

Why not? Most people's cars sit stationary for hours at a time and are rarely driven for more than a couple of hours at a time.

But electric cars use thousands of battery cells and a different chemistry so the situation isn't quite the same. Fast charging will reduce electric car battery life, but even the fastest charging points don't approach the equivalent the 6A into a NiMH AA.

Thanks guys im less ignorant now

One more question if I may

How long does it take to charge a couple of aa or aaa with this intelligent charger ? or is wise to do so that wouldn't harm the batteries ?
THx guys

Eneloop and GP Recyko. Eneloop is probably still the best.

And when Lidl have them for sale, the Lidl Tronic Pre-Charged (Low self discharge) Batteries @ £3 a set of 4 are also good.

Using one of these as we speak, cannot fault it - well I can kinda - the LCD needs a Backlight as its very awkward to read in some situations and like most smart chargers it has trouble detecting totally discharged cells (this is where those dumb USB Poundshop chargers come in handy to get the voltage up just enough to register in the smarty) Other than than those minor niggles it works rather well

That depends on their capacity and which setting you use. High capacity AA batteries at the 0.5A setting will take over five hours. Average AAAs charged as it's max speed will take 45 minutes.

The limitation is what the batteries accept gracefully rather than the charger, spending £15 on a charger instead of £5 isn't going to charge your batteries faster. The extra is for the other features.

The Duracell CEF27, which the amazon deal appears to be for, charges in pairs 2 / 4 cells, according to the Duracell website.

At 6000mah, not my 1000 guess, the only batteries with any hope of surviving heavy usage are likely Eneloop. Some conclude that basic high speed Duracelll pumps in 1500 mah, still way too high for longevity/capacity protection.

where from? I can only see them for the £20 mark.... post up the link or it never happened

This "intelligent" charger has left me somewhat bamboozled. I have some AA batteries (Eneloop Pro 2450ma) that I use with this charger. What charging speed should I use? 1000ma? One of the slower speeds? What would be the point in charging the batteries more slowly?

And when the battery starts charging, a display showing 0 starts counting upwards. Is it supposed to go all the way up to 2450 (the capacity of my battery)? Charging today, around the 1800 count it just "stopped" counting.

Bought this for £40 last year off amazon. Best charger I've ever had. Has saved me time and money. Rechargeable batteries die. This tells you when to bin.

I have a Duracell 5 minute charger and it can charge one at a time but I'm not sure maybe this one is different from the other Duracell one that you're talking about

Banggood or Gearbest a couple of years ago on a deal.
The Liitokala Lii 202 (a 2 cell charger) was an even better deal - paid less than a fiver (well, several times - I bought a few as they're so handy) and whilst there's no fancy LCD screen it's a proper intelligent charger that'll do LiFePO4 batteries too (not common, but useful for me.) Power input is from a microUSB cable so they're portable too, handy for leaving at work/in the car etc. And fantastic value.
Edited by: "tenohfive" 13th Aug

The HUKD dilemma. To embrace this as a really good deal; or sulk because you missed out a couple of months back when it was nearly a fifth cheaper? :-) I'll sleep on it.
