Price and Warranty

Budgeting for my battery purchase was important, so I compared prices across different brands and retailers. I realized that while I could find cheaper options, investing a bit more in a reliable battery could pay off in terms of performance and lifespan. Additionally, I looked for warranties, as a good warranty often indicates a manufacturer’s confidence in their product.
