Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sorry to hear that your GolfBuddy Voice is not taking or holding a charge.
I may confirm that, yes, your GolfBuddy Voice can have its battery replaced. Would you like instructions, and where to obtain either the replacement as a service, or the replacement battery so that you may do the replacement yourself... ?
