Energizer 2-Amp Battery Charger/Maintainer, 9-Step Smart Battery Car Charger, LCD Display, 6V/12V Voltage Detection for Auto, Motorcycle, RV, Boat,SUV

Current Applications: Tractor/Mowers. After researching a very large number of Battery Chargers/Maintainers, I selected the Energizer ENC-2A and purchased two of them (several weeks apart) because of 1) Current Customer Reviews (4.2/5.0), 2) 5-year Warranty, implying that it will last a long time, compared to other Maintainers with much shorter warranties or unusable warranties (cost to fix under warranty greater than charger cost, for example), 3) 2A Current Rating, 4) Ring Terminal Accessory to enable quick connect/disconnect, 5) It is a 7-Step (Stage) Smart Charger, 6) It can charge 6V or 12V Batteries, 7) The price was very good for the features, 8) Cords are certainly long enough, 9) It will charge AGM batteries, if they are salvageable, Marine Deep Cycle, etc., 10) Ability to fully charge discharged batteries, with voltages below 1.0V, if bad cells can be recovered by the Smart Steps, 11) Lightweight, and 12) Amazon delivery was great, as usual. I did not like the fact that 1) Energizer does not actually make the product and that you have to contact the real manufacturer (licensed by Energizer), which apparently is Bright Manufacturing, with Corporate Offices in Florida, if you have a problem 2) After a power outage, you must re-select the correct voltage (6V or 12V) before the charger "Energizes" or turns on - would have preferred a 6V/12V switch, so that the charger could start working immediately after a power outage, 3) Would like to see an LED Display with more information, but what can you logically expect for a Charger/Maintainer at a price of $20 delivered?

* * * * * UPDATED from 2 to 5-star! GREAT SUPPORT and great product! I posted the 2-star review below mainly because this smart charger wasn't smart enough to remember or detect if the battery was 6v or 12v and thus wouldn't start without having to manually select the option each time. A day or so after the review, a person from the company called me personally and offered to resolve the problem. They actually agreed with my complaint and CHANGED THE DESIGN as a result so it would automatically remember the last setting and start charging automatically as soon as it's connected to the battery. They shipped me the upgraded version for no charge even thought the return period was long past. You just can't get better service than this! The charger works perfectly now. On another positive note, I'd been having the leave the original charger at the open end of my carport since it needed to be manually started. That's resuited in it being essentially outdoors and exposed to rain for almost a year. I've went out and found it dripping wet on several occasions and still it worked perfectly fine every time. --------------------------------------------------------------------------------------------------------------- Disappointed by this not-so-smart charger If you connect the battery and walk away, you'll come back to an uncharged battery. The charger will be stupidly flashing its lights and waiting on you to tell it if it's a 6v or 12v battery. No-name cheaper chargers can auto-detect the type of battery and automatically start charging. Can't believe this name-brand one doesn't. Would have returned it but was past 30 days before i found this fatal flaw. Buying another to replace this one with. As for functionality, well it's a charger and it charges if you press the right button- twice.

Wow! I've been using this one for 5 years now, and it still works well and reliably. Additionally, it has extended the life of my car battery, so it has also paid for itself. You can't ask for more than that.

Seems easy to use for a beginner I was able to get really good instructions from internet.

Compact and easy to use.

I have been using battery tender and NOCO branded maintainers, but thought I would give this one a try. It was a mistake. It is too late to return, so I will likely throw them away. Already bought battery tender Juniors to replace these units as I bought two. The key differnce I found between these and the other brands is this one seems to provide a quick charge, then shuts down, where the other two brands will charge, then change to a float mode and keep the batteries charged. I put this on my new batteries to keep them charged in winter so they would be ready in the spring when I needed them. It appeared to charge for the first day, but when I checked again in a week, the error light was on. I reset, and same thing happened. I then decided to put a different maintainer on the battery, which immediately started to charge the battery. I wanted to see what state the battery was at, so I immediately unplugged the other maintainer and the batter was almost dead. It appeared to me that this unit actually discharge the battery. I did check the connections before switching, connections were good and made correctly. The other brand took more than a full day to charge since it is only a 0.80amp charger. I would not recommend this product.

Writing this 2 years after purchase. Great job, has held up and saved me time and money.
