**Note: Razor electric scooter/bike versions can be determined by locating your bar code ID on the battery cover and/or on the bottom of the bike frame. The 7th and 8th digit in the series will tell you the version of your product: 01=version 1; 02=version 2; 09=version 9, and so on. Please be sure you identify your product version before placing an order for a battery.
**Note: Not compatible as a replacement for the 10 amp hour battery for MX350 versions 1-8. Battery is also not compatible with units that have a serial number beginning with "MX".
