Good reliable charger

My wife and I are older and don't travel much. I am tired of my wife having to use her car only to find her battery is dead and expect me to rectify the situation immediately. She never left the car 2-3 times a week to charge the battery. When I got this charger and taught her how to unplug it before getting out of the car and plug it back in when she gets back, I was able to live my life with relative peace. I also have a smaller one that I've been using for 12 or 13 years to charge my…

Not for Li-Ion batteries

There is no information on charging voltage in the supplied manuals - LiFePO4 batteries can be charged with high current, but this requires a certain voltage. This charger was listed in a search but the documentation makes it risky while Deltron has other solutions with lithium ion modes. (Also, it has too much charging current for a typical lead-acid motorcycle battery - car only.) However, more cables are included! It included (1) a cable with ring terminals that could remain installed in the

Pros
  • Ideal for a small home

Pretty good value - jump starters, chargers and portable power supplies

I've used a used solar battery maintenance tool for years but it's sitting in the garage now. So I needed a battery service technician, but at the same time I also needed a charger. Due to bad timing, the wire broke and shorted out while it was sitting for a few days right after I started keeping it in the garage. The battery was so weak that the battery for the starter could not jump over. Reading about 9 volts. Researching on the internet, a car battery is supposed to be 0% charged when it…

Pros
  • Sturdy construction
Cons
  • Good but not great
