I looked for batteries that are designed for marine use, as they tend to be more robust and able to withstand harsh conditions. This consideration ensured that I wouldn’t have to replace the battery frequently.

Budget Considerations

I set a budget for my battery purchase, knowing that prices can vary widely based on the type and brand. I aimed for a balance between quality and affordability. Investing in a reliable battery meant I could avoid potential issues on the water, which would ultimately save me money in the long run.
