What is a 20350 battery?
“20350” identifies a cell size; it does not establish one universal chemistry, capacity, discharge rating, or cycle life. Check the exact manufacturer and model before choosing a charger or device. One Wurkkos listing, for example, specifies 3.7V and 1,400mAh for its 20350 cell. Those figures apply to that product, not every cell sold in this size.
Can a 20350 replace a 123A battery?
Do not treat the labels as interchangeable. Use the cell type specified by the device maker, and confirm the exact model’s dimensions, terminal style, voltage, and chemistry. If a device calls for a 123A/CR123A cell, do not substitute a rechargeable 20350 unless the device manufacturer explicitly approves it.
How do I check compatibility?
Read the device manual and the battery’s model-specific datasheet. Confirm that the device accepts the chemistry and electrical rating, and use only a charger approved for that exact rechargeable cell. A size label alone does not prove that a battery will fit or operate safely in a device.
