I'd suspect alternator first but if you battery issues started about the same time as the LED bulb installation then I may look at that first.

AutoZone and most automotive parts stores offer free in-car battery/alternator/starter tests you just need to remove the battery cover so that it is accessible to the test equipment.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

My 2007 Cayman 's battery keeps dying. I replaced the battery less than a month ago, and it's struggling to start again. I've got a couple theories for the cause. - It has 281,000 miles. Is it possible that the alternator is starting to die on me? (Obviously this will require further inspection by a mechanic) - I typically only drive the car on weekends. My commute is under 2 miles so I don't want to add unnecessary wear by driving the car and shutting it off before it's warmed up. If the car sits for 4-5 days at a time, would that be enough time to drain the battery? - I replaced my taillight bulbs with LEDs a few months ago. They work great, but they trigger "Check Left/Right Brake Light" messages every time I start the car. Is it possible that this is a parasitic draw on the battery? Thanks in advance!

If the alternator is dying or dead it’ll take your battery with it.. good way to tell, start it up and turn on the lights, radio and accessories and if The alternator is bad the car (spark) will just die at idle or under load… Of course checking it is another way. I tend to leave the hood open or the glove box open and it goes low or dead…I’ve never owned a car that a light left on will kill the battery so fast… your not alone get it checked though because if your spark is weak your going to load your oil with fuel, and we dont want that
