Features

  • Fully Automatic Charging: The charger automatically recognizes charging. If you forget to press the start button, it will start charging after 30 seconds. Once fully charged, it switches to pulse repair mode and turns off the screen to save energy, maintaining the battery at a safe voltage level for long-term storage. When the battery voltage drops too low, the charger automatically restores full output power and switches back to pulse maintenance mode after reaching full charge
  • All-in-One Compatible Design: Designed for 6V and 12V sealed lead-acid batteries in cars, boats, RVs, power sports, and deep-cycle batteries, including 12V calcium and lithium (LiFeP04) batteries, as well as 6V and 12V lead-acid batteries, including STD, AGM, GEL, Wet, MF, EFB, and deep-cycle batteries. The charger also has a memory function to remember the last settings, ensuring uninterrupted charging even during long-term use without worrying about power outages
  • HD LCD Screen and 8-Stage Intelligent Charging: With true 8-stage smart charging (desulfurization, soft start, bulk charge, absorption, analysis, repair, float, and pulse maintenance), it optimizes battery life and repairs batteries without overcharging or damaging them. The HD LCD screen allows you to view the charging stage and parameters at any time, keeping you informed of the charging status.
  • Battery Repair: Independent desulfurization and repair buttons allow you to manually desulfurize and repair your battery to restore lost battery performance, helping to revive old/idle batteries and extend battery life. If your battery cannot be charged, you can try the "repair" mode to fix it. Note: It cannot repair completely drained batteries.
  • Engine Start & Winter Mode: Engine start delivers 100A current helps activating your car battery to start your vehicle in 100 seconds. Winter Mode, +0.2v on the basis of the original charging voltage, better boosts your battery activity and charges more thoroughly in low-temperature situations.
  • Multi Safety Protection & ETL Certification: The charger provides multiple protections to ensure safe use, including spark-proof, reverse polarity, overcharge/discharge, overvoltage, overcurrent, overload, overheating, current backflow, short circuit, etc. The upgraded cooling system improves performance. ETL certification makes it safe to use.

    • Glad I bought this charger
Color: 6V/12V 2A/10A/Auto
I'm sorta old school when it comes to battery chargers but I thought I'd give this fancy dohickey a try. I can say that I'm very impressed with it especially for it's small size and weight. Pretty simple, just set the voltage between 6 and 12 volt and let it do it's job. With 2 boats, one old tractor and 3 cars this charger will get a good workout. I think you'll like it. ... show more

    • Far more than just another battery charger!
Color: 6V/12V 2A/15A/25A/Auto Pro
I had a completely dead, high dollar battery in my Vette. This unit brought it back to life and repaired it. I had it tested with a handheld meter and the results were bad battery, replace. So, I ordered this based on the features it offered, and it worked like a charm. Next, I hooked it up to the battery in the truck and let it do its thing and wallah. Truck now starts quick just like it did the day I bought it. I read some reviews that said it would not work if battery was dead. At first, I had the same problem, but I moved the clamps from the small side post terminals where the cables screw in and attached them to the large posts on top. She came to life, and automatically detected it was an AGM and went to work. I highly recommend this unit and very happy with my purchase. ... show more

    • no on off toggle switch
Color: 6V/12V 2A/15A/25A/Auto Pro
I purchased this mid October 2023. Review is almost one year of use, now end of August 2024. I use this to trickle charge the battery on a 25+ year old vehicle that loses electricity sitting in the driveway, because I hardly ever drive it. I use this device to make sure it is topped off every couple of weeks. If I drove my car daily, or at least once per week, I would not need the trickle charger. Before I purchased this conditioner, I had left my car unattended for a couple of months. Saw it on Amazon and thought I'd give it a try before having to buy a brand new battery for my old car. This device at first indicated that my car battery was unable to charge as a 12 volt car battery. Luckily this battery charger was able to step down and charge it as if it was a motorcycle battery. I thought I'd try that and get some juice into, before opting to buy a replacement battery. After a day of recharging from the lowest setting, I was able to recondition the old car battery back to life, restart the car, and be able to drive more than 100 miles on the recharged battery. Now I use it often to make sure my unused car keeps it's charge when I'm not driving it. I just wish that the unit had a physical on off toggle switch. Instead the on off of the device is by plugging it into the outlet. It's recommended to be used directly into a wall outlet and not into a strip surge protector. I use a heavy duty 10 gauge extension cable and a GFCI adapter that has an on off physical switch on the GFCI outlet for extra protection. The other thing that you have to be careful with this charger is using it when the weather is bad. Make sure you do not use this when it is raining. This trickle charger is a slow charger, which I like. It may take awhile for it to charge up the battery, maybe a few hours, depending on how depleted your vehicle battery is. I tend to not wait for the charger to reach full capacity of the battery. I charge it to 3/4 of fullness to make the battery last longer. YMMV. Overall, this battery conditioner has been a life saver. ... show more

    • Won't charge a dead battery!
Color: 6V/12V 2A/15A/25A/Auto Pro
WTF? If your car battery is dead, this device refuses to operate. (and if my battery is not dead, I don't need a battery charger.) Total waste of money -- stay away. The only way I could charge my dead car battery with this piece of Chinese junk was to get a 6V lantern battery and clip lead it in parallel with my car battery. Then, finally, this device detected a voltage and became operational. Of course it incorrectly assumed I wanted to charge a 6V Calcium battery (whatever that is.) But at least it started charging. Then the lantern battery got super hot, the outer casing turned brown and started bubbling and emitting smoke from the + terminal. By this time the clip leads were too hot for me to disconnect them. After a few more minutes, the lantern cell began spitting caustic battery acid on my hand! I now have a hacking cough and my right middle finger is bright red and won't extend. Lawsuit incoming. ... show more
