What is the difference between ordinary dry cell and alkaline dry cell in various temperature range?

According to long-term practical experience, using ordinary zinc-manganese dry cells in the following temperature range will have different results:

1. Below -20 ° C: The Battery is virtually dead. The capacity of the battery dropped to zero, mainly because the electrolyte was frozen into ice, completely losing its ability to conduct electricity. During thawing, mechanical damage will occur to the battery structure. 2. At -10 ° C ~ 0 ° C, most of the battery capacity has been greatly reduced, and it is no longer possible to obtain economical discharge effect. 3. At 0 ° C ~ + 10 ° C, especially with high current discharge and continuous discharge, the capacity of the paperboard type zn-mn dry cell will decrease obviously. The capacity of Paste Type zn-mn dry cell and stack type zn-mn dry cell will also begin to decrease obviously. 4. At + 10 ° C ~ + 20 ° C: in this temperature range, all the batteries discharge normally, and the working efficiency is the best. 5. At + 30 ° C ~ + 40 ° C: in this temperature range, the large size dry cell can work normally, but the small size cell has a big capacity loss because of the serious self-discharge. 6. Over + 50 ° C: most batteries self-discharge seriously. Battery structure can be mechanical damage, such as sealant bitumen and insulator softening or melting, or even lead to battery leakage.

Are there any batteries that work outside the above temperature range? Yes! It is an alkaline zinc manganese dry cell. Only it can take the place of paste-up batteries and cardboard batteries to occupy areas they can not. The operating temperature range of alkaline zn-mn dry cell is -20 ° c ~ + 60 ° C. The alkaline zn-mno _ 2 dry cell is the most reliable for the instruments operating at 0 ° C ~ -10 ° C. But when operating below -40 ° C, its capacity degrades so much that it only emits a small amount of electricity. It can be concluded that the optimal working temperature range of paste type zn-mn dry cell, paperboard type zn-mn dry cell and stack type zn-mn dry cell is between + 10 ° C ~ + 20 ° C, not suitable for high temperature or low temperature work for a long time. The optimum low temperature operating range of alkaline zn-mn dry cell is between 0 ° C and -10 ° C. As long as we can pay good attention to these problems, we can make zinc-manganese dry cell to achieve the best use of results.
