Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Benefits

This RL800 replacement battery is engineered for durability and reliable power delivery. AGM technology minimizes maintenance and maximizes resistance to vibration, making these batteries especially well-suited to outdoor robotic mower environments. The deep-cycle profile supports repeated charge/discharge cycles, delivering a long-lasting battery option that sustains performance over many mowing sessions.

As a high-performance battery, the unit offers excellent energy density and consistent output, helping your RL800 maintain blade speed and navigation over extended operation. Safety and quality certifications, along with factory-fresh manufacturing and a 1 year warranty, provide added assurance that you’re getting a product you can depend on. Beyond lawn mowers, AGM deep-cycle batteries are frequently used in UPS units, emergency backup systems, and to power portable tools or other DC applications requiring steady, long-duration power.

Installation is simple: reuse your original cables and hardware and secure connections using the nut & bolt terminals. If your RL800 has diminished runtime or takes longer to recharge, replacing both SP12-18HR batteries is a quick, cost-effective way to restore full operational capability.
