Welcome to MLMF, MachineMaster!
Yes, typically any mower with a starter needs a battery.
Regardless of what amperage you have on your current mower, you will need to pull the flywheel. Once you do that, you should see the stator and leads to the regulator (or electronic regulator box). Then, it's only a matter of taking the parts to your local small engine parts supplier and have them match up using the numbers. After the correct parts are acquired, it's a simple put together job but, you will need to hook up the battery terminals to a new/replacement battery.
We have many members here that may be able to explain or go into further details should you need them.
