EverStart Maxx Marine 40 Amp Marine Battery Charger and Maintainer

put harbor freight to ssshame. i bought a harbor frieght charger and not the cheapest .that mother literally looked and acted and sounded like bottle rockets going off when i attached the leads it was insane. i was left with wires hanging and clips covered in melted plastic on my motorcycle battery . dont ask about returns to harbor freight. walmart stands behind everything. and on top of that . there chargers dont blow up and have local deputys converge onto your home asking wheres the fireworks ...this is a true story and a real review ... true..(not the deputys, i threw that in. but everything else is true. ) honest csb

use it to charge all my batteries around my homestead, the cable ends feel nice and sturdy. great clamps. somewhat easy to use. jump start function a little slow.

I like this charger but it might not be the best option. It appears to be quality built for the price but as others have mentioned this charger is weird in the way you switch from lithium to lead acid. You push the top left button to change it but it still leaves you wondering if it's on the right setting or not. I charged six 8 volt golf cart batteries individually over a week and it worked as it should without any issues. If I were to buy another one it would be a diffrent model.

Packed with features, this is a very nice charger. i was able to charge several batteries in one evening including a 109Ah Deep Cycle that was only 75% full and a couple of 35Ah units that were at 65% and 80%. Nice and quiet and the display was easy to read.

the product did not work in my application. don't believe it is the fault of this product. I need to return it.

As an Advanced user... understanding %26 Trusting the " auto feature" without my manual input is frustrating

Read the instructions. Not as intuitive as other battery chargers. Could damage battery if not setup correctly

This is an extremely frustrating battery charger. I guess tries to apply some logic to charging batteries. I have some small batteries that all my other chargers charge just fine. This thing charges for a minute then goes to Battery Conditioning mode. Also, it is confusing to know if it is charging in standard battery or lithium mode. And as far as lithium mode, this thing does not seem to put out the proper voltage for lifepo4 batteries.

It didn't do the job we needed, which was to recover a failed battery. We gave it five full recycles to get it going and still would not hold a charge. Then my son brought a different charger over which did charge the battery and it has since been reinstalled in the car working. I'm choosing to return it

this item is a battery charger that has to plugged into ac to charge a vehicle which is complete nonsense when advertised as a portable vehicle charger
