PL4050, Pro-Logix 4-Bank, 20-Amp (5-Amp Per Bank) Fully-Automatic Smart Charger, 6V and 12V Battery Charger, Battery Maintainer, and Battery Desulfator with Temperature Compensation

We bought this charger for our farm truck which has four batteries and was constantly going dead over the winter. It has been extremely useful and reliable ever since. It's kept that truck batteries topped up, and it's been very useful when we need to charge or maintain the dual batteries in our PowerStrokes, too. It has four independent charge circuits, and each one independently supports normal or AGM mode. It has several self protection circuits to detect improper connection, battery over or under charge, etc. It works in extreme heat, extreme cold, and the rain and frost don't seem to bother it. We've been very pleased with it. If there's one complaint about it, it's that if the batteries to be charged are too low, it will not charge them. You will need to find a way to get some power into the batteries before it will start charging. We use jumper cables to a known good battery to sort of "trick" the charger into starting, but once it does start charging, it'll fully charge even a totally flat battery in a day or so. It's not a fast charger, it's 2amps per battery circuit, and it doesn't have a jump starter function. But if you have the time to allow the charger to work for a few hours or overnight, it'll fully charge just about anything, including four totally flat 1300CCA 6TAGM batteries overnight. This is a great charger and I highly recommend it.

Vraiment bonne article

Just hook it up and the charger does the rest. It keeps the battery charged and ready to go. After a while it will lightly put a small load on the battery and then charge it back up, just as if you were using the battery in real life. Excellent unit.

Voltage status not displayed. Not important to me as I use a volt meter but it may be convenient to others. All said I've already charged two batteries fully that I was ready to throw out because they didn't hold charge. Now they do and hold it well.

I've been looking for a good reliable charger and desulfator this unit is charging batteries that on my other charger said were 100% but very weak this thing is well built very good quality heavy duty wire leads I'm yet to try a low SOH battery on it to see if it restores sulfates batteries but so far I'm very impressed
