Is this a starter battery?

No. It is an auxiliary battery rated 1.2 Ah, meant for backup and accessory power, not for cranking the engine.

Which cars does it fit?

It is listed for Mercedes-Benz ML350 and S63 AMG from 2009. Check your VIN or the part number on your old battery before ordering.

Is $14.99 a good price?

It is the lowest of the four new prices tracked as of November 4, 2026, so it is a good price against the current field.

Do I need to code or register it after install?

Auxiliary batteries generally do not need registration the way a main battery does. Confirm in your owner's manual for your model.
