Buying Guide
What size and specs matter most: For ride-on mowers, the Group U1 size is common; ensure the battery fits your mower’s tray and terminal layout. Higher CCA improves cold-start performance, particularly in winter or shaded, cool environments. AGM and SLA designs are maintenance-free and leak-resistant, making them safer for regular storage and transport.
Key considerations
- Start power vs. capacity: If you have a larger engine or cold-start challenges, prioritize 300–330 CCA.
- Maintenance-free design: AGM (absorbed glass mat) or SLA (sealed lead acid) reduces maintenance needs and spill risk.
- Compatibility: Verify group size (U1) and terminal orientation (positive/negative) for your mower model.
- Weight and handling: Heavier batteries may require careful lifting; consider installation aids if needed.
- Warranty and shipping: Check product pages for any warranty details and handling considerations.
