It was crucial for me to choose a charger compatible with AGM technology to avoid damaging the battery. Additionally, I looked into the lifespan of the batteries, as AGM batteries typically last longer than traditional lead-acid batteries, often exceeding 5-7 years with proper care.

Cost and Warranty

Budgeting for my battery purchase was another significant aspect. AGM batteries can be more expensive upfront compared to other types, but I considered the long-term savings in maintenance and replacements. I also paid attention to the warranty offered by manufacturers, as a good warranty can provide added security for my investment.

Environmental Impact

As someone who values sustainability, I appreciated that AGM batteries are more environmentally friendly than some other options. They are sealed and do not emit gases during operation, which reduces the risk of hazardous spills. I felt good knowing that my choice was less harmful to the environment.
