Review on 🔋 Outerman 12V 24V Lithium Battery Charger - Automatic Smart Maintainer for Car, Boat, Motorcycle, Lawn Mower - Lead Acid or Lithium Battery - 6AH~105AH Capacity by Mark Bearden

I hardly used my car due to COVID so after about a month the battery was down to about 11.5 volts from not using it. I already had an old 6 or 2 amp charger so I used that to charge the battery to the required 12.6 volts. Unfortunately it took me literally 3 days to do this and this old charger got really hot trying to do its job. I needed something better. When I saw the Outerman MF-2B on the Revain list, it was just what the doctor ordered. I bought one yesterday and tried it out. Wonderful! It charged my battery to 13.0 volts in just 6 hours and when I checked the temperature of the case it was only slightly warm. The built-in voltmeter is a handy option that allows you to monitor the charging process. I compared the voltmeter on the unit to a laboratory digital voltmeter and they were within 0.1 volts of each other which is a very good accuracy. full 10 amps but now I believe. After turning the MF-2B off and holding the battery for a few hours, the voltage stabilized to the required 12.6 volts for a fully charged battery. The device is so simple and easy to use that I can now regularly charge the battery every 2 weeks or so. This is a great little unit. My only complaint is that the red and black wires tend to get tangled, but I solved this problem by gluing them together and leaving just enough slack to attach the terminals to the battery. This completely solved the problem. I am tempted to buy another one for my adult son but we are postponing that decision until Christmas.
