Your battery should never be this bad. One good tip is to keep the battery fully charged and dab some dielectric grease on the terminals to prevent corrosion. On average a battery should last you 3 years if you take care of it. Some go longer and some go shorter if they are abused. We’ve found the Kinetic dry cell batteries to be one of the best. Pro tip: Keep a set of jumper cables/jump pack on your machine if possible, you never know when you might need them.
