Duracell promises durability to Mar 2023 by the so-called Duralock, also a higher power in his own words by 40% compared to the in-house Duracell Simply when used in digital cameras
The assessment of quality is based on a simple measurement method for the simple voltage of the battery is checked, which should indeed be very inaccurate, but sufficient as a guide. Ultimately, the results thus measured open-circuit voltage is no real significance, exactly this voltage is measured with commercially available battery testers for 5-10, as well as using a multimeter. Another criterion is the experience I have gained during the operation and after 3 months.
I have the voltage on the one hand at delivery and during storage, the other with use / non-use of controls to obtain for me personally an approximate basis. Perhaps these values for one or the other are indeed helpful.
Function: _________________________________________________________
On delivery, the stress was on average: ~ 1,598V
After 3 months, the open circuit voltage is as follows:
Batteries in storage without use: ~ 1,593V
Battery in a radio clock: 1,475V ~
Battery in a normal clock: 1,488V ~
Battery in a beard trimmer; 3 times 10min use: ~ 1,464V
Batteries in a Wii Remote; Use about 12 hours ~ 1,333V
(The Wii reports a battery state of full here.)
From my already longer existing batteries (1.2V) I'm used to a tension under to 1,275V, then these are charged in about full. For storage, the open circuit voltage is at this about 1.235V. If this falls below 1.2V then shows eg the Wii Remote just under 50% at. This information just so on the edge. My batteries usually tolerated seasons of 6-8 hours (estimated value) before I boot again. (There are no expensive models!)
Conclusion: ____________________________________________________________
Of the batteries not only has leaked. All batteries used are also after 3 months still in function. It came as the clocks still no defaults, the 2 Wii Remotes still function properly without incident. The batteries stored have almost the original open circuit voltage, which can be on the suggesting longer storage possible.
Who puts on brand batteries value, will certainly not be disappointed with this one and I think you can invest the money in poorer and afterwards might annoy. I am satisfied with the batteries in any case and find for me personally not a criticism of justifying a point deduction.
Ultimately, you have to just do well and find whether and how long will they last and can be operated his experience with batteries.
Note: __________________________________________________________
I have the theme batteries a bit busy. It is far too costly and ultimately extremely complex for an ordinary consumer to determine the state of charge of a battery reliably. The measurement of the open circuit voltage (which is also a normal battery tester for measuring 5-10), in batteries a very very rough guide and help may be to keep in mind about when to stock, for example, batteries should recharge.
About batteries Judging can become a scientific challenge, and even today the limits have not yet been marked out entirely by far. This can be seen in the latest development regarding the Smartphone batteries.
Most forums and posts you will find, deal with rechargeable batteries.
There are a lot of values and factors that are needed to a meaningful determination of the true state of charge, including:
- Voltage of the battery when empty
- Charge amount during charging precedent
- Complete charging of the battery
- Nominal capacity
- Battery Type
- Age and the amount of self-discharge
- Shelf life after full charge
There are many different methods to determine the quality of a battery measurement technology, especially when it comes to the state of charge, including:
1. Voltage Test free of load
2. Voltage Test with load
3. The acid test
The 3rd method, also in conjunction with a voltage test, after my personal research is generally most reliable, especially with regard to the car battery and battery boot sector. This method proves to be in these batteries (AA and AAA) of course extremely difficult.
The second method also requires an examination of the acid in order to ensure the reliability of the measurement. Here, a consumer is required, which can be checked off.
The first method is the simplest and most common use for a sufficiently. Specifically: Check no load is not very accurate, but is pretty good for quick checks a battery.
As you can see, I have operated a little research and Alkaline batteries are not rechargeable, I have found very little. Finally, one can easily say: experience. When batteries has not last long or empty quickly, then you will not buy more just. This is the simplest approach.
