slow charging, great for maintaining and conditioning

slow charging, great for maintaining and conditioning
Glad to have a mechanic in the family... Pros ⁃ product quality ⁃ Compact ⁃ Easy to use Cons ⁃ Slow charging ⁃ Useless AC leads Great battery for maintaining and conditioning, not so much at charging. This charger stands up to the brands standard of Noco. Well packaged with everything you need. Multiple AC power leads come in the box, you really only need one. This is a bit of unnecessary waste. Each bank is completely independent and easy to use. This charger is pretty much plug and play, just connect the battery. No button to push unless the battery is dead. Instructions state it will charge even a completely drained battery. It will not if the battery has dropped below 5v. I had to jump start charging with another charger to initiate charging. Great for set and forget overnight charging. This is not powerful enough to charge battery in a couple of hours. Leads are very long and clamps are good quality, never had a contact issue. For the price quality ratio, I strongly recommend.

    Used this for my two 6V RV batteries and worked great! Both were quite dead (came up as under 25%) and this brought both back up to full charge in less than a day! Just plug it in, set it to the right type of battery and let it go. Easy to use, small, and a great value. Love it and would recommend.

    This is a well designed and built battery charger, can be wired to a battery bank and then you can forget about it, just plug it in when needed. The problem is the way it’s shipped, it comes with multiple cords designed for most countries around the world, I will not be travelling with my charger. The output leads are also way too long and the unit was packed in 3 layers of cardboard. All this excess makes the product more expensive, and wasteful.

    Great little unit, I just finished mounting it in shed in my back yard. I plan on leaving my two boat batteries there during the winter. I was a pain to hull my boat batteries to my house and down into the basement to charge them and on single charger once a month. Now I can just connect them and forget them until next Spring.

    I've always used Battery Tender in the past. After a lot of online research I decided to give Noco a try based on the additional features it has over Battery Tender. I've been using it for a little over a week now and it's been great at maintaining and charging my 2 motorcycle batteries. My only complaint is the proprietary charging cables. Had to fork out and additional $35 for 2 of the standard adapters. No big deal... Just an inconvenience. Both of my motorcycle came with the standard charging cable pre installed from factory.
