How long to charge new batteries? Process?

Can someone post the process for new batteries? I just purchased 2 new 7200/3000 batteries and want to get the best life out of them. Thanks for your help.

Hello COBRANETWORK,

I will be happy to help you.
Before we go into details, can you please confirm if you have VEX IQ or VEX EDR robots?
Also did you purchased the 228-2604 Robot Battery or 276-1491 Battery?


Please confirm.
