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.

The SP12-75 NB (12V 75AH) replacement battery is a factory-new, deep-cycle battery designed specifically for Theradyne Rover wheelchairs. Sold as individual units and intended to be used in pairs (Theradyne Rover requires 2 batteries), this high-performance battery delivers the deep cycle capacity and rugged construction needed for everyday mobility. Built with AGM and valve-regulated technology, it provides a maintenance-free, spill-proof power source that balances energy density and durability for reliable wheelchair operation.

Benefits

This SP12-75 NB replacement battery provides exceptional runtime and cycle endurance for powered mobility. Engineered as a deep-cycle unit, it tolerates repeated discharge and recharge throughout daily use, giving your Theradyne Rover the sustained performance necessary for extended outings and demanding terrain. The AGM and valve-regulated design ensures the battery remains spill-proof and maintenance-free, which simplifies ownership and reduces downtime.

The high power-to-volume ratio and energy density make this a true high-performance battery, delivering more usable energy per unit of space — particularly valuable in mobility systems where compartment size and weight distribution matter. The nut & bolt terminal design provides a secure mechanical connection for higher current demands and reliable contact over many cycles. Typical applications include electric wheelchairs, power chairs, mobility chairs, and mobility scooters, but the robust deep-cycle characteristics also suit emergency backup systems, UPS applications, and equipment that requires long-lasting power delivery.

Important installation note: the Theradyne Rover requires two batteries and you must reuse your existing cables and hardware to properly connect the new batteries. Choosing the SP12-75 NB ensures you get a long-lasting battery built to the same functional profile as the original, with UL and CE certifications for safety and performance assurance.
