EverStart Maxx BC4WE 4 Amp Automatic 12V Waterproof Automotive and Marine Battery Charger

The items (purchased 2) appear well made except for the battery clamps. Their design has insufficient recesses in the metal clamps and will not secure to standard battery posts. They repeatedly slip off. My rating would be better if the clamps were better, and only time will tell how effective their performance is.

Very easy to use. Connect it directly to the battery withe the connector that comes with the charger. Keeps the battery charged with the built in trickle charger. My utv slowly drains the battery as i found out. The manual recommended a 4 amp charger with a 1 amp maintainer. This one is perfect......

First of all, I read the reviews! Most say it will take hours to charge! Not for me only 2 Hrs.! My Jeep Compass started on first turn! The cord was long which I liked! Did not use the magnet that's attached to the unit and did not use the little hook to hang it! I was surprised how easy this was! I really not mechanically inclined! I watched a few You Tube videos on how to set it up It was simple! Make sure you have a long extension cord if your vehicle is in the driveway!

I have purchased this exact product in the past and it worked fabulously in helping recharge the battery in our 2008 Highlander. I have replaced the battery and it helped to maintain the charge for a few years. I decided to replace the charger and maintainer. I followed the directions but the recharger stopped working after a day. That never happened with the prior one I had and used for several years. Not only did I not get one charge with the charger, I can't get it to work any longer.

This Everstart battery charger and maintainer does a very good job as advertised. Its smaller than I thought it would be, but performance is as good as much larger chargers. I have two batteries for my truck, both newish. The one I keep in my toolbox I charge once a month n rotate to engine compartment, and I always have battery in toolbox. This Everstart charger has everything you need, led indicator, ring terminals and reverse polarity indicator. It's also built very sturdy and has a strong magnet to mount with. If magnet isn't your choice, it comes with mounting brackets, which is the method I will use. The Everstart battery charger also has two ways to connect too your battery, you can use conventional squeeze type clips or two ring attachments, simply remove the 2 nuts that hold clamps on your battery, put on the ring attaches, n replace nuts, no need to remove cables from battery. Everything is in the box. Its really simple to use even if you've never used a charger. Real simple directions are included. The led indicator let's u know when the job is done. This Everstart charger maintainer is just what I needed. It works with almost any 12 volt battery, also waterproof, for your boat. I highly recommend this charger.

This is a great charger. It is small enough to store when not in use. I used it first to charge the dead battery from my lawn mower. I connected it using the included battery clamps. I let it charge overnight and the light on the charger was solid green by morning, indicating it had a full charge. I re-connected the newly charged battery to my lawn tractor and it started right up. Next, as I was preparing my travel trailer for fall camping, both batteries in my camper were completely dead. I connected the first battery to the charger and it charged it overnight. I went to check on the status in the morning, expecting the light to be solid green, indicating a full charge. The light was still blinking. I thought I may have to replace the battery. But, I decided to leave it on the charger. By the evening time, it had a full charge. I put the second battery on the charger and it took a lot less time to charge that one. This isn't a fast charger. So, it is easier on the batteries. This charger is simple to use and pretty straight forward. It did a great job charging the lawn tractor batteries and the two deep cycle batteries for my travel trailer. I recommend this charger to anyone.

The charger is exactly what I was looking for to charge and maintain my vehicle batteries. I have two autos and a motorcycle and always have two sitting in the garage being unused. I had a charger on my motorcycle battery to maintain it, but one or the other of my autos was sitting unused for long periods at times. This charger solves that problem and does a fine job doing it. It is nice and compact and comes with the necessary cables and connection to use on a variety of batteries. One thing that I really like is that it has several ways to mount it. It can be mounted on the wall with screws through mounting holes at the corner, it can be hung from a nail or hook from a metal ring on the rear of the charger which folds out for use, or my favorite is it having a magnet on the back of the unit to attach to any metal surface on the car to hold it in place while charging. I'd certainly recommend it to anyone.

I connected this to my RV battery directly and also had the battery isolated. Checked today (about a week later) - solid green light on. Tried to connect battery to check voltage (via electronic relay), and relay wouldn't even connect. Checked voltage - almost nothing there. Tried to reconnect charger and it has red dot indicator. I'm now checking with larger charger. Voltage indicated on meter and charger .2V (I've never seen a battery that low). And this charger indicated solid green light. I think battery may now be toast, but we'll see with some conditioning. If so this charger just toasted it. Now I need to check other battery on my boat.

This charger works very well. It is water proof and comes with long leads for easy placement. I added an adaptor so that I can plug it into the power point inside the cab of my truck [ford keeps the power point powered on after the ignition is turned off] It has enough current to quickly charge and keep the float voltage at 13.2 volts.

even though the instructions say if the battery is dead it will not work. I had a dead battery and it took a whole day to bring back to life. From no blinking light to a solid light.
