1.75-Amp Car Battery Charger, 6V and 12V Smart Fully Automatic Battery Charger Maintainer, Trickle Charger, Battery Desulfator for Car, Lawn Mower, Motorcycle, Boat, Marine Lead Acid Batteries

This is a great motorcycle battery charger, it has 3 different charging stags, Trickle Charge, Maintainer and Battery Recovery. The Battery Recovery is awesome. It takes about 2 days to completely bring you battery back to life. This charger is pretty small so you can pack it away on your ride just in case. I've had this charger for about a year and it still works like it did when brand new.. Very good quality and a great price, seller shipped free and fast. W

can detach charging cable from unit, very convenient and functional for frequent recharging of batts not used much...small unit size beneficial for frequent uses. Instructions are basic...used Standard and (Trickle is stronger charge at first), haven't needed or used Repair mode as of yet. Great price, Great unit.

Works with Porsche 997 with sae auxiliary power outlet pigtail adapter (purchased separately) With the 12v cigarette lighter / auxiliary power adapter connected to the SAE connector, I am able to plug right into the passenger side, auxiliary power outlet. Which Porsche designed as a charging port or power port when the car is turned off. It is a permanently switched to port meaning that even when the car is off, that port has a direct connection to the battery. I like this product because it gives me both an amperage and a voltage read out clearly visible with the LCD display. Although some might disagree, I like that it stays lit when disconnected from wall power. Which means that it gets its information fed directly from the battery. This inexpensive unit gives me more information than much more expensive alternatives that have no visible read out. I’m very happy with my little set up! I purchased a two pack of SAE auxiliary/12 V cigarette outlet pigtail adapters for less than $10 here on Amazon. They fit snug and everything works as it should!

The tender works good on a working battery. Background, my battery was at it's end life when I bought this unit. My previous tender stopped working two or three weeks prior to purchasing which caused my battery to unexpectedly not hold a charge or hold up for a jump. Initially after buying it seemed the unit was not registering my battery as advertised. After reaching out to the seller and explained the situation, I was getting ready to return the unit since it seemed faulty out of the box. After jump starting the car failed with a known good jump box, I had the battery tested and it was determined the battery was past it's expiration. Since replacing the battery, the unit register's the battery as expected and has been trickle charging without an issue since. It connects and plugs in quickly. Switching between modes is as easy as the press of the button and hadn't had an issue since the battery was replaced. I have been using this for several months and it seems to be holding up well to the elements. I still have yet to try it in cold weather but seems to be holding up well so gar with the weather.

Seems to do a good job in all three modes and is still working after more than a year of use on 5 different 12volt batteries in the mild Marine climate of Southeast Alaska. It has reliably turned itself off after completing its task. It is considerably less bulky than other battery chargers. Good enough that I ordered a second charger for my vehicles that live in the heat of the Nevada desert. We’ll see if the repair mode can make those batteries last more than 2 to 3 years.

This 1.75-amp smart battery charger works great for maintaining and charging both 6V and 12V batteries. I’ve used it on a car battery as well as a lawn mower and motorcycle, and it automatically detects the battery type and switches modes without any hassle. The fully automatic operation makes it very user-friendly, especially if you’re not a battery expert. It’s perfect as a trickle charger and maintainer, keeping batteries topped off without overcharging. The desulfation feature is a nice bonus and seems to help revive batteries that have been sitting for a while. The unit is compact, lightweight, and easy to store, yet feels well built. Overall, this charger is a dependable and versatile tool for maintaining lead-acid batteries in cars, boats, motorcycles, and more. Excellent value for the price and great peace of mind for long-term battery care.

This charger is cool. I really like that it will automatically shut off so it doesn't over-charge your battery. If the power goes out (or you unplug it to use the extension cord for something else) it remembers the setting and will go back to what you asked it to do originally. I'll be getting a couple more of these for my other classic cars.
