Advantages of alkaline batteries over carbon batteries
① In the same model specification, the discharge time of alkaline batteries is usually 5-8 times that of carbon batteries. But the price is only about 3 times worse;
②, alkaline batteries can withstand greater discharge current than carbon batteries;
3. The discharge balance (or stability) of alkaline batteries is stronger than that of carbon batteries;
④. Alkaline batteries are not easily deformed, while carbon batteries are easily deformed;
⑤. The environmental performance of alkaline batteries is much better than that of carbon batteries;
⑥, the instantaneous discharge current of alkaline batteries can be larger than that of carbon batteries;
⑦. After being used under the same environmental conditions, the voltage recovery speed of alkaline batteries is much faster than that of carbon batteries.
How to distinguish between carbon batteries and alkaline batteries
One look: The commonly used AA alkaline batteries and AA alkaline batteries are marked with LR6 and LR03 respectively, while the AA carbon batteries and AA carbon batteries are marked with R6 and R03 without "L".
Second weight: Alkaline batteries are heavier than carbon batteries. For example, AA alkaline batteries weigh about 25 grams each, while AA carbon batteries weigh about 18 grams each. Because the outer shell of alkaline battery is steel, the outer shell of carbon battery is zinc copper.
Three touches: There will be a circle of grooves on the negative electrode of alkaline batteries, but there is no such thing as carbon batteries.
