Between the available balance and current balance, which is best to go by when writing checks, using the ATM, or a Debit Card?

Please check your Available Balance before writing a check, using the ATM, or your debit card because it shows you how much is currently available for use at that time.

There may be additional funds in your account, but they may have a hold on them. Although these funds are included in your current balance, they are not available for use at that time.
