Principal batteries of type D
In fact, batteries are the chemical sources of energy. But the processes that occur are irreversible. Not to be confused with normal batteries with rechargeable batteries. The latter can be recharged and discharged batteries must be recycled. If you attempt to charge in the standard battery, it will just explode and ruin your charger.
There are batteries of various types – Alkaline, "AA", "AAA", "C", and others. If to speak about batteries type "D", they can be saline, alkaline and zinc. Manganese batteries are low cost. True, and they will last very long. Besides, the saline elements in any case we must not forget the device. After a full discharge, they can leak.
Batteries based on zinc salt much better tolerate low temperatures. Their price is much higher. And of course, the most popular and reliable are alkaline or alkaline batteries. They boast a long shelf life and quite a high charge capacity. Of course such batteries can be operated in devices much longer salt. For example, the electronic repeller moles can work for no more than a month from four saline elements of type "D". Alkaline and it will last for almost a year.
Features batteries type D
The main characteristic of such elements is a power voltage. It is equal to 1.5 V. the Weight of one item of this type is 143 grams. However, alkaline batteries weigh a few grams more. If the weight can vary in diameter and height remain the same of 33.2 and 61.3 mm, regardless of the composition of the batteries.
As for the tank current, it depends on the type of batteries. For example, have the highest capacity alkaline batteries. Among manufacturers of highest quality are elements alkaline "Duracell" (18000 mA), "Varta" and "Energizer" (17000 mA). It turns out that this ratio also depends on the brand. Accordingly, the current capacity of zinc-carbon batteries will be much less. But their price is significantly different to the lower side of the cost of more powerful batteries.
In any case can not be used in one device zinc-carbon and alkaline batteries. This will inevitably reduce the capacity of the current and the gradual depressurization of the battery. Your device can easily break.
