Dry battery, every household is used for ultra low temperature batteries, such as home remote control, small radio, gas stove, and so on, everywhere it has its figure, but now the market on the dry battery brand so many, the price difference is quite big, then which kind of dry battery is more cost-effective?
Alkaline battery manufacturer bloomer visited the market and found that there are many kinds of dry batteries in the market, which are mainly divided into two kinds: alkaline and carbon, and some prices differ two or three times. What is the difference between a carbon battery and an alkaline battery? Which is more cost-effective?
ime of experiment: January 7th
Experimental equipment: 2 carbon batteries, 2 alkaline batteries, and electric toys.
Experimental process: put on the same electric toy to see which is more durable.
The basic battery is two or three times the price of a carbon battery.
But it's still a good deal
polymer bought the same brand of battery No. 7, one is alkaline battery, the other is carbon battery. The price of a set of alkaline batteries is 4.3 yuan (a group of 4 knots, averaging 1.075 yuan per node). The price of a set of carbon batteries is 1.8 yuan (a group of 4 knots, averaging 0.45 yuan per node).
Looking at the price alone, the carbon battery is much cheaper and the alkaline battery is 1 times more expensive. This quantity of electricity can not be seen and touched. How should we compare it? The test tool used by reporters is an electric toy powered train (which needs 2 battery 7).
Bloomer installed alkaline batteries and carbon batteries in the same power train and opened 2 small trains at the same time. When the power switch was turned on, the 2 trains ran like a joyous child. When the experiment started for one or two hours, the two trains were full of power and no difference could be seen. After third hours, the reporter found that the running speed of the small train loaded with carbon battery has slowed down, about 4 hours and 20 minutes, the train completely lost power, and the small train in alkaline battery ran for 6 hours and 10 minutes.
Well, let's comb it. The price of the 2 carbon battery is 0.9 yuan, which lasted for 260 minutes, with an average cost of 0.827 minutes per minute. The price of the 2 alkaline batteries was 2.15 yuan, and lasted for 370 minutes, with an average cost of 0.581 minutes per minute.
Through this small experiment, we can generally come to the conclusion that the price of batteries is basically proportional to the length of usage. Although alkaline batteries are much more expensive than carbon ones, their use time is quite reliable.
