Lights drain 2007 Toyota RAV4 battery

Car battery drained by leaving lights on.
Do I recharge or replace? Car is used for daily work commute (25 mi each way). Reliable start is a must.

Why replace? Use a portable battery charger until battery is fully charge.It takes a couple of hours on a slow charge. How old is the battery?

If the battery is over 4-5 years old, I would just replace it. But that’s me.
