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

The SP12-55 NB replacement battery uses AGM technology for spill-proof reliability and long service life, making it an excellent choice for the Invacare Storm RX.

This makes it a long-lasting battery solution that reduces downtime and maintenance.

Built with valve-regulated construction and a superior power-to-volume ratio, these batteries deliver higher energy density than many comparable cells. The robust build and U.L./CE recognition ensure safe, reliable operation in everyday scenarios. Whether navigating ramps, traveling across town, or using the chair for extended periods, the replacement battery helps maintain peak performance.

Common applications include electric wheelchairs, power chairs, mobility chairs, and mobility scooters.
