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

If you're looking for a budget-friendly alternative to a Battery Tender or NOCO, this NEXPEAK unit holds its own. The 7-stage charging profile is legitimate—it handles desulfurization and compensation charging quite smoothly. Leave it connected for over 4 days so far (trickle mode) without any sulfation buildup. The mode memory after outage is genius—power flickers during outage, picks right back up. Pulse repair extended life on a 5-year-old deep-cycle that was weakening. Clear LCD shows real-time stats so I know it's working. Protections prevented any over-temp, reverse, etc.. Extra-long SAE cord with clips/rings makes setup easy. I tested the voltage accuracy with a multimeter, and it’s spot on. It holds the float at exactly 12.5V in trickle mode, which is perfect for preventing gassing in lead-acid batteries. Just a heads-up: it will NOT charge Lithium (LiFePO4) batteries, so don't try it. For standard flooded or AGM batteries, it’s a no-brainer for the price. There is also a [3-Pack] product available but I only needed one. Best budget smart charger I've used—way better than basic trickle units.

WOW! Premium Function at a bargain price. I have a garage full of toys that have batteries, motorcycles, scooters, ATVs, etc... For years I have used only Battery Tender® products and they work well, however a few had died after years of service. I purchased Two of the Nexpeak® changers at half the price of BT and I have to say I'm impressed. - Charges 6V AND 12V - Has maintenance modes - Better display with more information - Same connector as BT - Smaller yet has a better charge rate - Includes both permanent and Clip type mounts for your battery with it Very happy with my purchase.

I bought a smaller amperage Charger/Maintainer and my Harley-Davidson Pan America ate-it-up & it died. I replaced it with this and it's worked flawlessly. I was so impressed, I bought a 2nd for my INDIAN Road Master. I really like the LCD screen - it's a great 'visual' to see battery level & voltage versus only a small light like many other models. It charges pretty fast - and once the battery is fully charged, it switches 'OFF' to Maintainer mode.

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.

As a mechanic I've been using a Nexpeak OBD2 scanner for years and it's been great. When it was time to replace my $10 Harbor Freight trickle charger for something nicer this was an obvious choice for only $5 more. The built in battery indicator screen is nice to have and the fact it has auto safety features as well as multiple modes are some nice things to have. Using it to maintain my AGM Harley battery and I have no doubt this thing will last for years. Its well built and the hard wired pigtails can be left on my battery and simply unplugged form the unit and tucked away when I want to ride. I had an old Harley brand trickle charger with the same pigtail/plug that died years ago but always left that wiring attached to my battery. Its not exactly the same shape as the plug included with this charger but the polarity is the same and it fits just fine to connect with this charger. Buy with confidence, its easy to use and charges quickly for such a compact unit. Not as fast as a full size charging box but thats not what this is designed to do in the first place. I haven't tested its ability to bring an old battery back to life but based on their other products I've used I see no reason it wouldn't work as long as the old battery isnt completely beyond repair.

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

Incredible little battery charger. I got it to use on my mower and it works great. Easy set up just plug it in, turn it on and it's ready to rock.

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.
