Alerts and Warnings

If your application runs on multiple batteries, make sure to replace all of them at the same time or you will dramatically reduce the lifespan of the new batteries by mixing them with older batteries.

You have to install your replacement batteries in the same original configuration they came out and are required to use your existing hardware and cables to reconnect the replacement batteries when applicable.

It is your responsibility to verify the battery or batteries being ordered match the battery or batteries in your application prior to placing your order. Please check your:

  • existing battery dimensions (Length x Width x Height)
  • quantity needed to replace all batteries
  • voltage and amp hour requirements

Manufacturers may change requirements without notice. BatteryGuy is not responsible for incorrect orders - if you need help, please contact us.
