One thing you might try is moving the battery cable leads from one post to another and then back again, this can help get a better connection and improve power flow.

Another thing that could be helpful would be checking your starter solenoid for damage or corrosion; if there are signs of either you should replace it right away before it causes more problems.

Even though batteries don’t typically last very long, they are designed for 500 charges before needing to be replaced; some last longer while others don’t.
