Data backup battery for D3-330/D3-340 and DL405 CPUs
The DL305 and DL405 CPUs have a lithium battery to retain the application program and retentive memory when the system is not receiving power from the power supply.
Typical battery life is 5 years. This time period includes PLC runtime and normal shutdown periods such as preventative maintenance and power outages.
The CPU has indicators which tell when it is necessary to change the battery.
However, if your battery has been in your system for an extended period of time, you may wish to take added precautions to ensure that the system memory will be retained by installing a new battery when shutting the system down for a period of more than 10 days.

Note: Use D2-BAT-1 for D3-350 CPUs.
