Battery won’t stay charged

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. You did not mention the original cost of replacing the starter and alternator. What was happening then? It's not normal to replace both components unless you have a good reason. When the battery light comes on, it is a sign that the charging system has failed. You have to figure out why. Is it a concern with the alternator? The wiring connector to the alternator? Is it a problem with wiring? That's pretty much it. The charging system works when it works, and when it doesn't, the light comes on and you have to figure out why. The air conditioning is a separate concern - if it works - I would say wait until it does not.
