🔋 Schumacher Fully Automatic Battery Charger with Engine Starter, Boost, Maintainer, and Advanced Diagnostic Testing - 85 Amp/30 Amp, 6V/12V - Ideal for Cars, Trucks, SUVs, RVs Review

Won't charge my 100Ah AGM battery. Apparently it is designed for batteries up to 68ah (according to the instructions). Can work normally with smaller capacity batteries.

This product stopped working after a few months and Schumacher really can't get a replacement under their warranty program. I waited over a month so I had to file a business complaint with the Better Business Bureau.

Professional assignment as an automotive technician to maintain voltage for computer firmware. It does the job. I wish the "brackets" that the cables wrap around were better designed because they just periodically fall out. Maybe it could be a design change for the next iteration.

specifications as good product unfortunately it's junk I ordered the first one made a loud clicking noise and the digital display was dead so it was replaced that second and digital reader didn't work, it makes a terrible noise at startup, garbage in the box! Find a quality charger from Speedway, a great charger for all your needs.

This charger has all the features I need in a charger (at least on paper). But the button to switch the display from volts to the battery level does not work. The tech support call was a joke; Either you wait more than an hour and nobody answers the phone, or you stand in line for the "automatic gong" and nobody calls you back. It's too late to return the item but at least it seems to charge the battery. I don't think I would trust him to service the battery or float. It was necessary to go…

Easy to use. Fully alert detection system, simply plug in to do this. Guaranteed charging Choose slow or increase the current and get the job done quickly. This model has cables long enough to allow the charger to remain on a hard surface (your carport) and reach the battery at the height of an average car. I drive a Jetta. Has a quick start function. No wireless device. Requires AC service setup for those who can keep up with the battery pack. Great product at this stage with no real extended…

I have 6 and 12 volt batteries that have to be recharged from time to time (when there is too much energy or too little solar energy). These include old school liquid cell batteries, Gell Cell and AGM. Wet and AGM batteries are arranged in four rows. Schumacher handles it well. It first checks the battery and then you can choose the level or speed of charging. It's smart enough to know if your batteries are being mismanaged and need to be charged or balanced. However, I have one real complaint.
