AG33 battery

Is the button battery model AG33 the same as the AG30 battery?
AG33 button battery is the same model as LR44 battery, AG30 button battery and LR1130 battery are also the same model, but there are more names for button batteries.
These two are the same series of button batteries, both of which are zinc-manganese button batteries. Each model is divided into mercury-free and low-mercury, that is, environmental protection and non-environmental protection, which are related to export. In fact, the difference is not very big when used. If it is not exported, low mercury is also OK, depending on the requirements of each product.
introduce
Generally speaking, there are two types of button batteries, rechargeable and non-rechargeable. The rechargeable ones include 3.6V rechargeable lithium-ion button batteries (LIR series), 3V rechargeable lithium-ion button batteries (ML or VL series); Charging includes 3V lithium-manganese button cells (CR series) and 1.5V alkaline zinc-manganese button cells (LR and SR series).
The more common button batteries are AG3, AG30, and AG33 batteries used in toys and gifts. The battery model on the computer motherboard is CR2032, which is used for CR2025 in electronic dictionaries, and CR2016 or SR44, SR626 for electronic watches, etc. .
