Thank you man for the video, I just bought one of this chargers and now I will know how to use it right of way.

I just want to correct one thing for safety measures in case someone completely new is watching this video. You should connect the battery tender itself to the AC outlet first, then change the battery type or voltage. After that, you connect the alligator clips to the battery terminal or the sealed connector bit. The battery tender may default to something that does not match your battery type or voltage, so you don't want to connect the tender to the AC outlet last. I'm sure it's fine if it's the wrong configuration but just in case.

great tool for seadoo 6volt battery - now i will use on my rig. thanks!

You done a great job breaking things down

Love this Battery Tender! Been using it on all my cars.

excellent support thank you

Great video, especially for us that new to a battery tender. Thanks for the video, it was very helpful. God bless you and family!

Thanks

Thanks for the video it was very very helpful. Good Job.

Thank you. Very informative

Great information. I bought the same charger and this helps. 👍

Thank you for your review

One question to be able to charge it needs to be connected to the electrical current, that is, it is not a portable travel object?

Section 16 subsection e) says to plug positive to positive but then plug negative to the chassis or engine block away from battery 🔋 You can create gas in the battery and it blows up and spill acid all over you !

I just bought a 3.0 amp. So I am wondering how to use: clip red to red (positive) and black to black (negative). Then plug in. Am I right? Once the light is green, which sequence to use? Remove clips and then unplug?

Intro fire af 🔥

Can this work for completely dead battery? I can’t see anything turning on my dashboard when I put my keys to ignition.

I need one of those for my cars so i can keep the battery up on them instead of ruining them during winter when they freeze and crack the case.

Oh boy Lmaoo I just bought the wrong thing I thought this will jump start my car

I have a Prius 2008 and recently bought this battery tender. Is it safe to plug in while the car is connected to the battery or you suggest unhook the battery connection from car before clipping the charger to the battery? I saw in your video you have the battery connected is it safe? How long can we leave battery on the charge?

Can you leave it plugged in & hooked all winter? On like my mower while it’s in storage?

My car battery died so I bought this battery tender. A tutorial online said to connect the red clip to positive and the other clip to a random metal part of the car. I noticed you connected both to the battery. Are both methods correct?

Jason Camissa or Adam Sandler ?

how long we can charge the battery tender ? i did charge for 17 hours but it was not fully

My orange light is on a d the green light that says 12v is flashing, what does that mean?

i always thought you had to take off one or both cables off the batter to do any kind of charging. didn't know you can charge the battery with the cables on.

Your battery has to have 3 volts for this to work 👍

So you don’t need to disconnect the battery from the car? Just clip it directly? Thanks.

What is the input voltage ?

So you don’t have to plug into an outlet at all?

Is this portable? Can I charge this and put it in my bag while riding my back- use it in case of emergency?

Just pick one up last week

The label on the cord says "use in a well ventilated area " and what about closing the hood.

Why the light on the 12v start flashing??

is 4.5 amps too much for motorcycle battery?

How long did it end up taking to max out battery? Very easy video to understand by the way, thank you.

Has anyone who's has experience with this used it to charge lithium ion batteries? How was your experience using it. I'm thinking of getting one. One of the purposes I would use it for would be to charge my 12v lithium ion batteries I use for my fishing electronics . Usually you have to get a separate charger for lithium batteries as SLA chargers don't read the voltage properly and will never fully charge it .

"So we're gonna go ahead and read some instructions...uhhh...probably not" haha! Those instructions are the size of a short novel! Do you happen to know if I can do the following: Run a power inverter (BESTEK 300W Power Inverter) from my tiny RV’s cigarette lighter, plug this Battery Tender into that, and then charge the house batteries (2 giant “golf cart batteries”) when I drive? Thanks!

i have a battery that drain every 2 days.so can i keep the connectors all time connected? so i just need to plug/unplug when i drive it?

It takes me 5 hours to charge it fully and change it from the dead(my lawn mower). I'm checking it in an hour

I’m confused. The directions on the battery tender say NOT to connect the negative clip to the battery but to a heavy gauge metal

Why does the 12v flashes

12v light blink what it means?

i charge my car for a few mins and the 12V green light start to blink...do not know why

Can this start my car after I left the lights on all night. That's all I need it for. I personally don't care about maintaining my battery. Thanks.

Could you do like fuel line change to a dsm or something? I have to do it to mine but idk how

Did you ever try using it to charge a motorcycle battery? Can you reduce the amperage to 1.5amps instead of 4.5?

Hi! I have a question, So I need the battery tender connect to the car and plugged at the same time, the it will start to charging??? But I don’t have a charger 🔌 for the car that’s why I got a battery tender😂😂😂😂. Is there any product that need no charger?? I can charge it at home, but not at the same time…can you please point me out??? Thank you so much!!!

Why is my 12v/6v indicator light blinking?

I know you're all excited and enthusiastic about this stuff you just bought, waving everything around in the air just like an excited Italian waves his hands around to add impact to his narrative. But . . . the camera can't focus on stuff you wave around a few inches in front of the lens 🙄 The viewers can't possibly see anything useful if you grab bits of stuff from here and there and wave it around a few inches in front of the camera 🙄. Slow down Dude. Curb your enthusiasm. Hold the stuff in front of the lens at a good focal length and *hold it still for 5 seconds.*

?anybody use this for Lifepo4.?

I bought that same item from Costco also but you say it is intended for indoor.. I am planning to park my car in a parking lot for 3 weeks for a trip in New York winter. How do I maintain my battery? Thx for the info.

2 hours? Wow. I definitely didn’t buy the right thing.

Can’t you use this without plugging it in? It’s supposed to be portable

Charger unit pluging into wall is bs, it should be wireless or plug in somewhere else portable

How much did you pay at Costco

Tik Tok video turned into 11:32 minutes

I didn’t realize it has to be plugged into a wall. I bought it in case my battery died on the road. 🤦🏾‍♀️

For the sake of accurate information: You are completely wrong in your statement that car alternators cannot fully charge a car battery. Car alternators are rated as an example: 50/120A 13.5V, this means 50 amps at low rpm usually 1500, 120 amps at high rpm about 6000, 13.5V is the voltage these ratings are taken at. An average alternator amp rating is from 45 amps to over 140 amps depending on the application. Alternator Voltage varies with demand from below 13.5 to 14.4V or so. So you can see that the alternator in a car is putting out a lot more charging amps than most home battery chargers. This Battery Tender model in the video is 4.5 amps. This is 10% of a car alternator charging at it's lowest and only about 3.2% of a car alternators high output charge. It's going to take a lot longer to charge a battery fully a 4.5 amps than at 45 to 140 amps. The only problem is if you only drive short distances and the car sits a lot. In that case the drive maybe to short to charge the battery and as it sits in between the short commute drives the charge continues to go lower. This battery charger is excellent at maintaining and charging batteries. Particularly if you have only short commutes and the car sits. If you live in an area where its cold and on your short commute you use the car heater, heated seats, defroster, lights, radio then this is going to be very hard on the battery and a Battery tender like this is a very good thing to have. This charger will not overcharge batteries because it has a microprocessor that monitors the battery and will change to maintenance mode. The moral of the story is at least do a little reading and research before you post videos.

This isn’t at all what I thought it was when I bought it. I thought you hook it up to the wall and let the pack charge then you can carry it in your car for emergency use 🤨 I wasted my money buying it😡

Not helpful at all

Dude, 7.30 minutes of useless talk. Just get to the how quickly.
