Direct Replacement for Razor MX350

This 12V 9AH sealed lead acid battery fits the Razor MX350 as a 100 percent OEM replacement. It uses advanced AGM technology for leak-free operation in any position. The unit is maintenance free and rated for an expected life of four to seven years.

Reuses Existing Harness

Installation is straightforward because the T2 terminals match the original wiring, allowing the old harness to be reused. The sealed AGM design prevents electrolyte leakage from terminals or case during handling. Gas recombination exceeds 90 percent, reducing the risk of pressure buildup.

Limited by SLA Chemistry

The sealed lead acid chemistry delivers reliable backup power but offers lower energy density than modern alternatives. Capacity is fixed at 9AH, so runtime cannot be extended without adding more batteries. Recharge cycles and deep-discharge tolerance are constrained by the AGM design.
