Furthermore, many modern vehicles purposefully maintain batteries partially charged to save gas. It's pretty dumb since the savings are crap and the affect on the battery is not zero.
So, plug in a maintainer every weekend or once a month and keep that battery healthy. Have a vehicle in storage? Better have a maintainer.
Return that sucker and get your money back

Lithium wouldn't be a normal car or boat/motorcycle/atv battery.

Costs 1/2 a battery 50% off so what's the savings?

Common usage is to hook up motorcycle/marine/lawn mower batteries during winter storage.
Charge a car battery that has been sitting around for a while.
In my instance we have a 2nd car we do not use everyday- so during those especially cold winter snaps I will hook it up to the car's battery the day before, so I know it has a full charge to start in the morning.
