AGM batteries are generally more durable, vibration-resistant, and offer better performance than traditional SLA batteries. They are also maintenance-free, meaning you don’t need to add water. All of the listed products are SLA/AGM.
Other Important Features
- Voltage: Typically 12V for riding mowers.
- Amp-Hours (Ah): Indicates the battery’s capacity – how long it can deliver power. Higher Ah generally means longer run times between charges, but it’s less critical than CCA for starting.
- Dimensions: Double-check the dimensions to ensure the battery fits within your mower’s battery compartment.
- Warranty: A longer warranty (like the 15-month warranties offered by UPLUS and MARXON) provides peace of mind and indicates the manufacturer’s confidence in their product.
- Lead Purity: Batteries using 99.99% pure lead (like those from UPLUS) tend to charge more efficiently and have a longer lifespan.
- Compatibility: Check the product descriptions for compatibility lists. MARXON U1 320CCA and MARXON U1 360CCA batteries boast extensive compatibility lists.
