That is interesting. From the many posts I've read, the "delivered" resting voltage on these batteries can vary widely. Just curious, how did...
So as of this morning, about 9 hours off the charger, the Optima is reading 13.19V on my Fluke MM. :) Looks like I'm good to go!
Understand completely, thanks.
Thanks Mendel. I haven't installed the battery into the car yet. Hope to do so tomorrow. Per Sam Spade's suggestion, I'm going to see at what...
Charging completed after 8 1/2 hours. Battery voltage has been dropping steadily since being removed from the charger a short while ago, and is...
Thanks SS. I was wondering about that. It's now at the 6 1/2 hour mark. Still sitting at 14.75V.
Nearing the 5 hour mark. Has reached 14.75 volts between the terminals, with the charging clamps connected and still charging. I believe the...
Thanks Sam. It has been charging continuously for about 3 hours so far...still going. It is presently measuring approx. 13.7V between the...
While I'm waiting for the battery to charge, thought I'd ask a separate question about the installation. Is there a "trick" to removing the vent...
Battery is charging as of noon Pacific Time. Let's see how it goes. This should be interesting. :) -Kizzy
I went with the Schumacher SEM-1562A. It works with AGM batteries. It charges at 1.5A, and also works as a maintainer. Yes, it's a little slow,...
Thanks SS. I'm going to pick up a charger today and charge it overnight. Having done more research, the Schumacher SEM-1562A will in fact charge...
I want to say thanks again to bisco, Sam Spade, and dolj for your advice on charging the battery. I'm going to follow it, as I've come around to...
Thanks for your response. I do see where you are coming from, and I'm re-thinking this. I'll look into getting a charger to test the battery's...
Yeah I'm not too impressed with the B&D model. This one looks like it would do the trick. It's the next higher model Schumacher charger....
I respect your opinion, but am going to have to politely disagree. The manual for that specific model charger plainly states that it is not to be...
Thanks, I see now what you meant. As for the two chargers, that Schumacher model will actually not work as a CHARGER for the YellowTop, only as a...
Following up on my earlier post. Thought I'd do a little research into low-cost battery chargers/maintainers. The Pep Boys near me has these two...
Assuming, for a moment, for the sake of argument, that it merely maintains the battery at 12.6V, why is that necessarily a bad thing? So long as...
Can you explain why you think this would happen? Doesn't the Prius charge the 12V battery while in the Ready Mode? I've read dozens of posts...
