Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Mostly because of price.....no brainier, I also had a 25 dollar gift card from Autozone. The original battery was in there for 7 years, and was showing signs of weakness at startup. The H6 (46) : $161.99 CCA 730A The H7 (47/94R) : $181.99 CCA 790A The H8 (49) : $152.99 CCA 900A I just added a nut under the battery tray, since the last hole is not threaded. Strangely, the AGM's (Platinum line) had less warranty (3 years) than the Lead Acid (Gold line - 5 years). Interestingly, the voltmeter on the dash now goes to 14V during start up (and remains there for several minutes), then it goes just under it. It never got close to the 14V line before, even 5 years ago with the old battery.

POST 2Original post

I'm headed the other direction (lighter weight). The last time I lifted that heavy battery out of its spot, it just didn't feel healthy for me old lower back. Quite a reach to be deadlifting 80 pounds or whatever it is.

POST 3Original post

Initial start voltage will go high because battery isn't initially accepting a standard charge rate post engine cranking.

POST 4Original post

I replaced my Porsche battery(Interstate) after 6 or 7 years as well. I still have an original battery on my 16 year old 21' center console boat, although there are 2 batteries.
