Duracell Products Rechargeable Rechargeable Charge Status

Memory effect is a term that is thrown around with talking in regards to a rechargeable battery, but there are a lot of incorrect conceptions around what memory effect is. Memory effect is where batteries aren’t competent to hold as much charge as they once could.

When a user experiences less capacity in the battery than they once had, they believe that this is memory effect, which is not the case.

The most mutual reasons for batteries no longer outputting as they once did are the following:

1) Over-Charging: Charging aa rechargeable batteries, even the best rechargeable batteries, for too long will result in the peak voltage dropping off much more speedily than it once applied to. It would appear to an end-user that the battery capacity had in fact decreased, nonetheless this is not the case. The is more mutual in high-drain buyer electronics such as handheld widgets and digital cameras. The device is expecting to see the higher voltage, else it formulates a low battery warning or similar. Some electronic gadgets which are not high-drain may not even see any divergence if the battery has a voltage drop. Over-charging is much more likely with cheap trickle (slow) chargers.

2) Age and Use: Shock horror, the more you use a rechargeable battery, the less effective it is due to chemical reactions! It doesn’t matter whether you run Duracell rechargeable batteries, or a no-name brand, in the long run they are all going to be less effective than they once were. The thing to look out for is the number of expected recharges you may get out of a battery. Many of the Duracell rechargeable batteries will give you around 1000 charges before their life ends. Looking at the grand system of things, this is potentially one full charge each day for a few years! Every rechargeable battery likewise has an effective life, before you will start out to see some degradation of capacity, once again a good rechargeable battery will give you at least a year or two. If you are a regular user of batteries you will make your cash back tenfold before calling for to buy new batteries, in comparison to purchasing single use batteries.

So will have to you wholly discharge a battery before recharging?

Draining a battery to 0 volts (completely dead) may potentially cause damage, leading to a reduction in life of rechargeable batteries. If you obtain Duracell rechargeable batteries which potentially give you 1000 full charges and have a battery with 90% charge remaining, would you actually want to flatten it entirely with a charger (many do this for you) before recharging?

Use the batteries normally and when performance is no longer adequate for the purpose then just recharge them again. If this is genuinely bugging you then a good deal of of the top rechargeable battery chargers will let you discharge a battery to a specified voltage, before the recharging cycle begins. This is more friendly for the battery life than draining it altogether to 0 volts and is similar to what would occur if you applied rechargeable batteries in a digital camera. A digital camera will not drain them to 0 volts, it requires a sure voltage in order for the camera to switch on.

So what will have to you do?

People are unnecessarily caught up stressing when it comes to memory effect, and things that look like memory effect. Duracell rechargeable batteries or any of the best rechargeable batteries will most likely do the job, so just run out and get a lot of and stop worrying.

Let’s say you spend $20.00 on 4 AA Duracell rechargeable batteries and give them only 100 of the 1000 suggested charges over a couple of years, which they will without apparent effort achieve, each battery will end up costing 5c a charge ($20.00 / 4 / 100).

Good luck finding single use disposable batteries at these prices!

Good Batteries, Bad Charger
By NLee the Engineer
This package (CEF14DX4N) includes four new Duracell ‘Pre Charged’ NiMH AA cells, plus a simple charger. The batteries are similar to the Sanyo eneloop low-self-discharge cells. In fact, based on their identical technical specifications and physical shapes of (+) and (-) terminals, I am convinced that the Duracell Pre Charged AA is actually SANYO eneloop AA underneath a dissimilar wrapper. Therefore all the good things you heard regarding eneloop utilise to Duracell ‘Pre Charged’, too.

The ‘value charger’ (CEF14) included here, however, is not a good value because:

1. It is a timer-based mute charger, meaning that it doesn’t observe when cells are full charged. It plainly charges at 360mA for 6 hours and turns off. You have to wait until your cells are completely exhausted before recharging, other than as supposed or expected they will be over-charged. With a ‘smart’ charger, you may choose to top-off your rechargeable cells any time.

2. It may only charge either 2 or 4 AA cells in pairs. This is very inconvenient if you have widgets that require odd number of cells.

3. It may only charge two AAA cells, and you can not charge any more AA cells at the same time.

My counsel is to get the CEF23DX4N package for just a few dollars more (*). It comes with four Duracell Pre Charged cells (2xAA + 2xAAA), but the included charger (CEF23) is far superior in each aspect. It even operates from your vehicle battery, and doubles as an USB charger, too.

I was only half-right when I boldly proclaimed that “Duracell Pre Charged AA are rebranded Sanyo eneloop cells” in my firstborn review. It turns out that the firstborn batch of Duracell AA cells I purchased from Amazon are made in Japan, and those are identical to eneloop (both mechanically and electrically). But not long ago I purchased a good deal of more Duracell AA from a warehouse club. Those are made in China, and they are identical to the Rayovac Hybrid.

[Update on Feb 15, 2010]
I have confirmed that the new Duracell ‘Value Charger’ has assorted improvements over the old model:
- Works from 100-240V AC (instead of just 120V AC)
- Able to charge 4 AAA at a time (instead of just two)
- Semi-smart charge termination (stops when BOTH cells are wholly charged)
The only remaining drawback is thet it charges in pairs only.

(*) [Update on Oct 7, 2010]:
Duracell has discontinued the magnificent CEF23 charger (at least in the US) last year. So prices for the remaining inventory have skyrocketed. If you need an inexpensive charger that may handle person cell, consider the Sanyo eneloop MDR02 2-cell charger.

Better charger now?
By Randy A. Woodward
I purchased the CEF14 charger with four batteries and the charger supplied is not the same one pictured, nor is it a “dumb” charger as numerous have described. It may also charge four aa or aaa batteries and is not fixed to two aaa’s again as a great deal of have described. When I tested it, dissimilar batteries charged at dissimilar speeds and the charger swapped modes to a trickle charge when a set became to the full or entire extent charged.

As for the batteries themselves, they do without doubt seem to be comparable to Sanyo Eneloops or Rayovac Hybrids at a somewhat lower price.

Perfect for digital camera
By Mike R
Not sure how Duracell did it, but they solved the one con with the Ni-mH type batteries. These pre-charged, Ni-mH batteries don’t discharge when not being used, so they’re perfective for digital devices. This charger with 4 batteries doesn’t cost much more than just the 4 batteries alone. Here’s what you do: acquire twice as galore of these batteries w/ the green label as what your digital camera will take. While you’re using one set in your camera keep the other set in this charger. Then, when the set in the camera go dead, just swap them out with the set that’s in the charger. You’ve always got a set of fresh batteries and no waiting for batteries to charge, plus no buying batteries for a long time. This is more costly initially but saves a lot of $$$ in the long run.
