Frequently Asked Questions

How long does the complete restoration cycle take?

A full restoration cycle consisting of two complete discharge and restoration cycles will take approximately 42–45 hours depending on initial battery condition. Annual preventive maintenance cycles to maintain peak performance only take 12-13 hours.


What types of batteries can the Xtender restore?

The Xtender can restore all sizes of lead acid batteries including flooded, sealed (gel), and valve regulated types.


Can I restore multiple golf carts at once?

The Xtender unit appropriately sized for golf carts, 93-M1001, can regenerate any golf cart with batteries sized up to 72V 300Ah. It is not recommended to regenerate more than one cart at a time, as doing so eliminates the capability to determine the capacity of either individual pack.


Can the Xtender be used for for manual charging and discharging?

Yes, you are able to fully customize the charge/discharge algorithm in order to perform manual charging/discharging.


What is the typical revenue that can be generated performing battery restoration services to end users?

For performing a full battery restoration, it is typical to charge between 25%-30% of the battery pack's retail value.


Do I have to remove all of the batteries from the golf cart before I can start the process?

When restoring golf cart batteries, removing them from the cart is unnecessary. You are able to park your cart directly next to the Xtender to begin the restoration.


How do you identify a bad battery and/or battery cell?
