What is the difference between aaa type battery R03 carbon battery and lr03?
1. The nature and magnitude of the current are different
R03 carbon battery and LR03 are both AAA batteries, but R03 carbon battery is carbon 7th battery, LR03 is alkaline 7th battery, alkaline battery is 3-5 times larger than carbon battery, and alkaline battery current is also larger than carbon battery .
Second, the characteristics are different
The negative electrode of the alkaline battery, that is, the end that Meiyo spits out, will have a circle of grooves (sometimes it is wrapped, you can find it by pressing it), while the bottom of the carbon battery is flat, or add a gasket (dial You can find it by opening the coat).
3. Different weights
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. Because the shell of the alkaline battery is steel, the shell of the carbon battery is zinc.
4. The logos are different
Commonly used No. 5 (AA) and No. 7 (AAA) alkaline batteries are marked with LR6 and LR03 respectively, while No. 5 and No. 7 carbon batteries are marked with R6 and R03 without "L".
