Question

Will a DL205 CPU lose the program if it doesn't have a battery?

Answer

No, it will not. The ladder program is stored indefinitely.

The DL205 does have an internal super capacitor that will hold the retentive data, during a power cycle. If you need to have the retentive data stored for longer then a couple hours, then you would need to use the PLC battery, to retain the data.

The 230 and 240 use the D2-BAT
The 250(-1), 260, and 262 use the D2-BAT-1
