OEM battery vs original battery

OEM batteries are generally preferred over "original" batteries due to the higher likelihood of being newer and having a verifiable history of use and storage. "Original" batteries, especially those purchased from non-official sources, may be old stock or mislabeled, potentially leading to performance issues or safety concerns. 

OEM (Original Equipment Manufacturer) Battery:
Definition: Batteries manufactured by the device manufacturer or authorized suppliers ensure compatibility and meet specific design requirements. 

Advantages:
Higher Quality: Typically undergo rigorous testing and quality control processes. 
Warranty: It often comes with a warranty, providing peace of mind. 
Seamless Compatibility: Designed to work perfectly with the device. 
Potential for Better Performance: May offer slightly better performance and lifespan due to their manufacturing standards. 

Disadvantages:
Higher Cost: Generally more expensive than after-market alternatives. 

"Original" Battery (Often Aftermarket):
Definition: Batteries sold as "original" but may be from a different manufacturer or old stock. 

Advantages:
Lower Cost: Can be cheaper than OEM batteries. 

Disadvantages:
Potentially Lower Quality: May not meet the same quality standards as OEM batteries. 
Compatibility Issues: Could have compatibility problems or not function as expected. 
Safety Concerns: May not be as safe and reliable as OEM batteries, potentially leading to overheating or even explosion. 
Potential for Reduced Performance: May have a shorter lifespan and degrade faster. 
Lack of Warranty: Often lack a warranty or have limited warranty coverage

Recommendation:
For critical applications or when the cost is less of a concern, opting for an OEM battery is generally recommended to ensure compatibility, safety, and performance. If cost is a primary factor and the device is not critical, after market batteries can be considered, but careful research and selection are necessary
