The coin cell is not used in an on-line lock. The AD200/AD250 locks only use the coin cell battery to mainatain the real time clock during AA battery changes. The WRI400, AD300 and AD400 do not require a local clock since the ACP keeps the time.
The coin cell is only provided in the AD300s and AD400s for ease of possible re-classing to AD200/AD250 locks.
