Was just on lifeline's page and am impressed with its depth
They say 14.3v max +/- 0.1v acceptance
and 13.3v +/- 0.1 float
and a recommended 0.2c minimum current and
bulk current should be as high as practical and up to 5xC is tolerable
at the standard 77f
http://www.lifelinebatteries.com/manual.pdfI've also been researching Northstar AGM batteries.
Their list of approved chargers is much bigger than Odyssey, and they do not seem to have a minimum initial current. I'd like more info.
What is nice is that northstar makes a group 27
http://www.northstarsitetel.com/northstar/engine/literature.phpThey are very pricey. and boast similar numbers and claims as odyssey, but appear to be even heavier in the same group size.
Apparently Batteries Plus sells these relabelled as X2Power
