They are selling with buzzwords, while these batteries dont offgas too much, they require higher charging voltage, which your car wont provide, which in turn means it will never fully charge, which means it will die quick.
As i have always said
Do not purchase equipment or parts which cannot be supported, unless you have other accommodations for it
E.g. the best AC are made by trane and carrier, but are useless in Pakistan. No one can service them.
For batteries, use whats recommended by the manufacturer, and make sure its insulation or heat shielding is intact and also make sure the terminals are top notch quality, not the sloppy type.
