Battery Tender Plus 2 Bank Multibank Charger - 2.5 AMP (1.25 AMPs Per Bank) - Smart 12V Multi Battery Charger and Maintainer for Standard, AGM, and Lithium LiFePO4-022-0165-DL-WH

This item was delivered and thrown into 2-3” deep puddle of water in the pouring rain outside my fence , all on security video , luckily it was raining otherwise, somebody might’ve stole it ! So as it laid in the puddle for many many hours, the box has soaked up the water and his product sat underwater for hours. I let it dry out for a couple of days after pouring all the water out of it. And I plugged it in and to my surprise it worked And it is still working weeks later I was going to return it, but it takes too long to get a refund so I’m gonna take the chance since it works and hopefully it stays working so the product is awesome since it runs after being underwate , so I give the product 5 STARS !!! The delivery guy and Amazon I would give only 1 STAR , because the driver didn’t want to get wet so he threw the package in the puddle not even in my yard over my fence outside my yard about a foot from the sidewalk and if it would’ve got stolen they would’ve told me it was delivered And there’s nothing they can do about it unless I make police report Which would be false because it was not stolen on my property because Amazon did not put it inside of my property. Amazon is really getting bad. They used to be good. This is happened many of times in the last year or so. maybe Jeff Bezos should stop taking all the money and pay his Drivers better so they do better !

Works great use every day

I already have a 4-port charger used to keep the motorcycles charged up. Had it for many years. Trouble free. Easy to buy extra connections, extra extensions ,etc. Needed this new 2-port charger to go out for the tractor, mower and generator. Just as good as the 4-port. Already installed in permanent shelf location and charging the equipment. Buy Battery Tender, you won't go wrong.

I have used this charger to maintain batteries in my riding mower, two motorcycles, and two batteries in my F-250 diesel. The two separate charging banks work well. It has indicator lights for each bank that work independently and properly - no 'sharing' of lights leaving you guessing as to the status of each battery.Also, I was on the verge of replacing the two batteries in the F-250 because they had sat in the cold and heat, only getting driven infrequently, over the past two years. They had gotten to where they would barely hold a charge. After hooking them to this Battery Tender, I believe that these batteries have been (at least mostly) 'repaired'. Attaching this charger and slowly charging and de-sulfating these batteries has gotten them to the point where they 'appear' to be as effective and hold a charge as well as ever. I can drive the vehicle and not worry about bringing along a charger and/or cables, 'just in case'.The same is true for all my other batteries - the engines all start as though they have a new battery in them by using this two bank Battery Tender. I feel like this unit has more than paid for itself versus the cost of replacement batteries.Recommendation - if you have more than two batteries to maintain, buy extra battery leads so that you can easily alternate this unit to all of the batteries. I have had great success alternating this unit between four batteries (three-four days between switching).Updated 11/08/2009 - since I have been so satisified with this unit, and I now have more travel coming up, I said the heck with it and bought another one - Amazon's price made this a no-brainer. Now I don't need to alternate the charger between batteries - they are all covered!

This unit charges and maintains two 12 volt batteries at once. I'm using it to maintain the charge of both a marine battery that I use for my travel trailer, and also the battery for my Craftsman garden tractor. The unit is nicely compact and takes up less space and one less 110V outlet in my garage tan would two separate units. It has the 'three stage' micro-processor controlled charging program that works independently for each of the two batteries.My results so far are really great. This unit--like the other Battery Tender charges--is much 'smarter' than a cheap trickle charger or than a regular battery charger from a few years ago. You connect this unit to the batteries and leave it without worrying that your batteries will become overcharged or damaged. I do check battery electrolyte levels every two or three weeks just to be sure that the level is not getting too low, but thus far am seeing no sign that this unit is causing my batteries to evaporate electrolyte unduly. When I take the batteries off the Battery Tender and meter the voltages at the terminals, they are fully energized and ready to go to work.The Battery Tender is keeping my batteries in shape and ready to work with a minimal amount of work on my part and no worry of battery damage due to overcharging. Well worth the price in my book!

I use this charger on my two seadoo jet ski's to maintain the batteries. After one week, bank two quit working with just a flashing amber light. To ensure the battery I had plugged into bank two was still good, I swapped it to bank one and the battery that was on bank one I switched to bank two with the same result. Bank one is working as it should, but bank two has lost its ability to charge the battery. I will contact the seller to see if they will replace.Other than that, the product was brand new and well packaged in the original Battery Tender packaging.Update - I contacted the seller and after a few minutes of troubleshooting with them they agreed it was faulty and shipped me a new charger. I haven’t had an issue with the new one at all. It kept the batteries charged over the winter months with no issues bringing them out of winter storage.
