Search-Alkaline or Rechargeable Batteries?

Batteries are very important items for the preparers, they are the power sources for flashlights, radios and many other equipment. Some time ago I was curious to know which battery most interesting to have at home and stock.This curiosity generated a research that was very interesting for me because it clarified and taught some points that I did not know.

As I always cherish for simplicity and clarity, I will omit technical details that are beside the point to answer the question in the title and make the reading dull for some.

So I’m going to give you only two details that are important to know:

MAh-Abbreviation for milliampere-hour

It is a measure of CAPACITY, ie the longer, the longer your device will be working.

Example: Let’s say a flashlight consumes 100 mAh. So if you use a battery with 600 mAh you will in theory have approximately 6 hours of illumination. If you use that same flashlight, a battery with 1800 mAh would have 18 hours of illumination.

In normal or alkaline batteries I have not found the quantity of mAh of them, but in rechargeable batteries this information is always informed, at least in the brands I have used.

In this case the rechargeables gain from the alkaline ones.

V-Abbreviation for volt (s)

Here I think the clearest definition I can give, without departing for technical jargon is to categorize this “v” as “STRENGTH.” Ever noticed that using an alkaline battery in the flashlight with the passage of time the light is getting weaker? This is because alkaline batteries, besides the capacity (mA), also lose this “force” during use.

On the packaging of them says it has 1.5 V, but this is only the moment you put it on the device for the first time, because with the use it goes down with the use for 1.4V… 1.3V… 1.0V. Once again the rechargeable ones gain, because although they appear in the packaging that they have 1,2V, this value stays constant during practically all its time of use. As long as it has capacity (mA) the force remains.

Every cell works basically with the conversion of chemical energy into electrical energy, so over time these chemical elements will lose their capacities, so the batteries have validity. This information is usually found printed by the manufacturer on it’s own.

Another great advantage of rechargeable batteries is that they have a longer shelf life and newer ones like Eneloop promise to be able to be recharged for 1800 times, which means that 1 battery of these saves you the purchase of 1800 alkalines! Another interesting feature in these new batteries is that they do not lose charge like the previous models. The self-discharge of it is very low, including the manufacturer states that even after 5 years they will still have 70% load. And to improve, they do not have the infamous memory effect that makes the old batteries go losing their load capacity.

It became clear to me that rechargeable batteries, although they cost more, become more interesting in the long run because of the economy provided, the time they last, and also the characteristics described in this little survey.

And you, do you have any other way to store the energy you need?
