The terminals at the battery are VERY suject to corrosion and generally need to be removed, cleaned, burnished, and retightened each spring.
Leading evidence: 'Clean burnished, and retightened each spring' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Clean burnished, and retightened each spring' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

b) If I'm going to replace the battery, should I get a Porsche labelled battery from the dealer, or a top-rated retail battery like the DieHard or Duralast?

If someone has not moved your emergency front hood release to the be reachable from the tow plug on the front bumper of the car then you make have a difficult time opening the front hood to replace the failed battery (you need power to release the hood!).

Is the hydrometer something that my Porsche dealer's service folks, or even a service station, would have on hand to test car batteries?

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.

My 99 996 cabriolet appears to have a crummy battery. The one time I put the top without first starting the engine, it refused to start, and I had to get a jump from AAA. Today, I started the engine, remembered that I needed to get something out of the little locked box between the seats, turned the engine off, unlocked the box, and when I tried to turn the engine on again, all I got was a frustrating "click-click-click" sound
. After a jump, the battery guage happily reads around 13 or 14. So two questions:
a) Do people think this is a battery problem, or something more worrisom electrically? And,
b) If I'm going to replace the battery, should I get a Porsche labelled battery from the dealer, or a top-rated retail battery like the DieHard or Duralast?
Thanks,
Nick
My observations:
1. You can't tell anything about this battery without a hydrometer test for specific gravity. That will tell you if you have a bad cell or if the battery is good and you have a power drain somewhere.
2. If someone has not moved your emergency front hood release to the be reachable from the tow plug on the front bumper of the car then you make have a difficult time opening the front hood to replace the failed battery (you need power to release the hood!).
3. If it turns out to be the battery (likely) then you can replace it with any good quality type 48 battery. I would suggest finding one with a vent that can be connected to a hose (like the original).
Good Luck!
