It’s important to follow the manufacturer’s guidelines to avoid damaging the battery. I also looked for batteries with a longer lifespan, typically around 300 to 500 charge cycles, as it meant better value for my investment.

Compatibility with Devices

Compatibility is another critical factor I considered. Before buying, I always checked whether the battery is suitable for my devices. I found that some batteries are designed for specific applications, so I made sure to verify that the dimensions and connector types matched my needs.
