All battery sales are final. No returns.

Troubleshooting and potential warranty claims are handled directly with the manufacturer of the battery or the manufacturer of the battery's authorized service provider. 

If your machine comes with Lead Acid Batteries, AGM batteries, Gel Batteries, TPPL Batteries or Lithium Batteries, and you want to switch to a different type of battery, you will need to change the charging profile (algorhythm) in the charger to match the battery type, or damage can occur which is NOT covered under warranty.
