🔋 Energizer 2-Amp Smart Charger: Fully-Automatic Battery Charger, Maintainer, 6V and 12V Trickle Charger with 7 Step Smart Charging Technology Review

The device works properly. He successfully located the problem with my 12v marine battery which was still under warranty and allowed me to return it to the shop for replacement. Judging by other reviews, time will tell durability. A CAUTION. If you have a completely discharged battery (e.g. no lights in a car etc.) this charger will diagnose the battery as damaged and will not start charging. I had a basic 10 amp charger 30 years ago so once I charged the battery a little it charged it.

I'm an automotive technician and really liked the Energizer charger I bought from Revain. I plugged in my multimeter and monitored the charging process while the charger was connected to my battery, measured the voltage and current and it showed it was exactly to spec. While it is too early to tell how long the charger/maintainer will last, I am very happy with what I have purchased. Out of all the options on Amazon, I think this one is the best, not only for the options and features, but also…

Good smart 9-step charger! I've used this charger twice in the last month and have had great results. He does what he has to do. I like the desulfation feature as it can help regenerate the battery by cleaning the lead plates. Small and compact. The rear LED is ideal for dark situations. The cables are quite long, the clips are ok. The device itself is well made in the hand. Like a 5 year guarantee. I had no problems with this unit auto zeroing as every time I press it the unit starts charging…

I used the NOCO brand battery tender and service but settled on this one. There was an error. It's too late to return it so I'll probably throw it away. I have already purchased a junior battery tender to replace these units as I have purchased two. The main difference I've found between these and other brands is that this one seems to allow for a fast charge, then turns off when the other two brands are charging, then switches to float and keeps the batteries charged. I put it on top of my new

I have an old (1970's) charger that still works; but it is slow. So I figured I'd buy this charger to "go into the 21st century". I have a new battery in my car (6 months); but I don't drive it often. The battery was dead; So I put this new Energizer charger on it. Energizer charger showed error #2 - battery voltage is less than 1.5 volts - replace battery. I then put my old 1970's charger on top and as I type this it charges nicely. The bottom line is, if your battery is low, you need to…

My ENC8A never goes into maintenance mode. 120Ah deep cycle battery, 1 month old, never used, previously charged with a friend's 10 amp Schumacher which worked perfectly. This thing quickly rose to 14.5 volts, but won't go into service mode. I figured (Schumacher took about 4 hours from the store with a new battery, I expected less than 2 since it was already charged) so I went to bed believing it would do the job. BAD IDEA. When I remembered checking it, it had welded the battery in almost 14…

I am totally impressed with the Energizer 4.0 Amp Charger. I work in the taxi industry and my taxi has to work 24 hours a day. As soon as a taxi shows signs of a battery problem and the alternator fails, I change the battery immediately. I had 3 used batteries that were defective. And left them in storage. Battery number 1. This battery has been in storage for 7 years and I thought I would use it as my main depot. The battery voltage was between 6 and 7 volts (very low). I connected a 4 amp…
