The last commute was quite a bit better. Car seemed to drive, dare I say, very warm-weather-like. No apparent slowing down at all. The lowest battery, however, registered a horrifying 11.26v
. The next one up was the one that was on the desulfator for 2 weeks which showed a respectable 12.15v. I am firmly convinced now that desulfators are the real deal. Mega-Tron confirmed his prowess with a 12.50v after commute- setting a new record.
edit: I think investing in a second battery desulfator would be more logical for me than any other battery or battery related product.
There has also been a lot of activity on the "alum battery" boards that is apparently debunking my theory that converted batteries have a lower voltage. Also, there has been much talk of how they can take a serious deep cycling and still beg for more. Now THAT'S my kind of battery! And one thing about alum batteries that lends a lot of credence to them is that they cannot be "hot" filled- when you make the electrolite and put it in, the battery needs multiple discharges before it becomes efficient, while regular lead/acid batteries are good to go once assembled. That's what makes an alum battery a manufacturer's nightmare, and why it is not worth it for them to make any. Further experimenting is necessary....
