with its 3-amp charge keeps batteries for cars, trucks, ATVs, boats, motorcycles and lawn mowers charged and maintained for you-even on those vehicles with intermittent use

At 3 amps charge please do not think this will charge a dead battery. It will only top it off in a reasonable time and keep it topped off.

If you left on your radio, radar device etc and you walk out in the morning
this will get you going again, if your car won't start.
ITs worth the money...or get a bigger one.

I've charged a dead car battery less than 8 VDC at 2A without issue. Just need to charge 24 hr before voltage return to 100% charge state...12.85 VDC

Got one today. It is working as advertised. Thanks OP.

It'll charge a battery, slowly. I think someone is better off getting something from HF instead for a few bucks more, or buying one of their small tenders for a few bucks.

It will only top it off in a reasonable time and keep it topped off.A typical car battery is rated 60 amp*hours, so ideally it would take (60 amp*hours)/(3 amps) = 20 hours to charge a completely dead battery. But charging wastes about 40% of the energy, so adding 40% gives 28 hours.

Charging efficiency depends primarily on SOC for lead acid batteries IIRC.

Thanks for the post.

Comes up in cart at 37.99 this morning. Darn really wanted one for 22.99.
