Is a Johnson AGM starting battery fully charged at 12.68v???
Buying a new chassis battery, it took me forever to find somebody who actually had an AGM one in stock, as opposed to just claiming they did.
Got it yesterday. Johnson Control,
sold under the Duralast platinum label from AutoZone. Dated August of last year.
Not topped off when I got it. I idled the van for a while yesterday, ran out of time. Battery ended at 12.76 but I assumed that that was just because I didn't charge it long enough.
Today, hooked up a smart charger, and it reads as fully charged, although voltmeter said 12.68 before plugging in charger.
Not much luck finding specs online for this particular battery, and guys at AutoZone didn't even know what AGM was, so I can't ask them.
Is it possible that it really is fully charged at 12.68, or have I got a dud battery? It did start the van, although weather is warm.
Don't know what I would do without you guys.
