Good Affordable Car BATTERY CHARGER: Pulse Charger REVIEW (12V24V Pulse Repair Charger)

A good affordable car battery charger or cheap car battery charger. This Anhtczyx pulse charger review covers this dual 12V24V pulse repair charger which makes an easy way to keep a battery during lockdown or for times when a Battery doesn't hold a charge. The Anhtczyx smart car battery charger is the perfect tool for easy battery restoration or DIY old battery repair. This is another pulse repair charger review which features 8A charging for 12V and 4A for 24V batteries. This is an improvement on my 5A Foxsur battery charger. This is a good way to desulfate or remove battery sulfation. Consider this an easy approach to how to desulfate a battery or DIY battery desulfation. There are many similarly branded smart pulse chargers like buddygo, Foxsur etc.

Hi, Thanks for your video. Could you please inform me once you full charge the small red charger then how long it took time to full charge your car battery?

[@DIYAutoworksNG]

This model does not include an estimate for when charging will be completed. However, when the battery is full the screen will display 'OFF'. The only other time you can get an 'OFF' notification without the battery being full is if its a badly sulfated battery. In such cases, switching to repair mode is recommended.

Ok. First all GREAT VIDEO! However I have a 24v battery from Walmart. Idk if it’s a deep cycle and I don’t know if that matters. I’ve never used one of these batteries before. It’s new I’ve used it a few times. My question is how do I get it on a 24v charge? When I plug it in it says 12v but when I bought it everyone told me that I had to have a 24v charger. So I bought a new charger this one. I’ve charged group 31 deep cycle batteries on my old charger. So im confused why it wouldn’t charge 24v.

[@DIYAutoworksNG]

I haven't hooked this up to a 24V battery before so can't say exactly. I was thinking it should smartly detect a 24v battery and do the needful. Have you checked the documentation that came with the charger? Also be sure to find out what type of battery you have and select appropriately. Charging protocols differ based on battery type.

[@dennislewis7602]

@@DIYAutoworksNG I think I got it. So the battery says 24 v however it also says it’s a 12v battery. I plugged it in and now it says full charge. So I’m thinking it puts out 24v but it is a 12 volt battery. My hydraulics for my car were the same way.

⁠ Once it says full on the display, will it continue on trickling charging the battery after that? Or is there another setting that you have to put it on for it to be a trickle charger so that we could leave it there for three months without having to worry about the battery dying?

[@DIYAutoworksNG]

@@eberxeber9310 yes you can. I suspect the voltage is lower than the charger's pick up threshold (usually around 8.5volts).

[@eberxeber9310]

I measured the voltage, it's 14.1V. Wikipedia says the reason could bei "Acid stratification". I will try to charge it with an uncontrolled charger.

[@RingZero]

Thanks for the video. however, I still do not understand how can this be a 140w charger if is rated for 12v and 8Amp max.

[@DIYAutoworksNG]

Thanks for watching! 140W is just the max power it would draw from the AC outlet during peak operation. Remember that to charge a 12v battery the charger needs to apply a voltage above 12v. I have seen it go up to 14+v. Also, note that while it delivers output voltage/current to charge a battery, it also needs some power for its internal processes to run. E.g power to run its cooling fan.

[@alexh549]

These are not 100% efficient so will draw more power from the wall than they actually deliver to the battery.

If I recall, I think ERR means there's an internal battery fault. Can't be recharged. Maybe 1 or 2 cells are damaged.

[@mammycher8895]

It would definitely take some time. The manual doesn't clearly state this. It also depends on whether you want to use the repair function rather than the normal charging. Repair lasts from 8 - 24hrs. My 5A Foxsur charger manual stated 22hrs for charging a 100AH battery so I would imagine that with this being an 8A charger it should be less.

[@sajanlohana3848]

@@DIYAutoworksNG But it takes too much time

[@DIYAutoworksNG]

Yea. At this price point, you would expect this kind of speeds. However, battery charging does take time even with the more expensive chargers. A lot depends on the state of the battery. An old, sulfated battery will take much longer than a battery that just lost its charge.

Does this charge dead car batteries sometimes they are to smart and cant detect a lower voltage so don't turn on

I just got one of these, and upon connecting it to a very dead battery, it says "ful" on the display. I'm assuming it's because the battery is so dead the charger cannot read it correctly, but it's strange that it would show full. It doesn't show voltage or temp or anything. Instructions are no help at all. Just put it on repair mode, and will let it run overnight in hopes that it will fix it, but the battery is severely discharged. I just jumped the car a couple months ago though, so you'd think if you can jump it, you'd be able to charge it.

[@DIYAutoworksNG]

The battery is severely sulfated with most of its cell plates covered by the sulfation crystals. The reason it showed full is because the little unsulfated upper parts of the plate will quickly get charged and the charger is fooled. The phenomenom is documented in the manual. Such batteries should be charged via repair mode just as you've done. Whether it will be revived sufficiently for use depends on a lot of factors.. Let us know how it goes.

[@michaelwarren4273]

At about four minutes in, I heard you saying that you connect the negative first. This seems to make sense to me, but the instructions say consistently to connect the positive first. I would guess that in any electronics, it's very important to have a ground wire, and that is connected first. Isn't that right? (ground, earth, it's where excess current can go). I also Google'd that question, and it says to connect the positive first. Red, positive, or "hot" is the same thing. Wouldn't the current possibly find a ground, or short to ground, possibly through your own body?

[@DIYAutoworksNG]

You'll notice that earlier on I connected the positive first which is best practice. At around the 4-minute mark I was explaining the connection in a positively earthed car (which are not common). Connecting the positive first reduces the risk of arcing.

I have a question. I just bought one and when i plug it in to charge the battery charger, how do i know if it's charging. It just days ," OFF" which i assume means its at full capacity charge. Not even sure tbh sigh

[@DIYAutoworksNG]

You have to connect the leads from the charger to the battery first, then plug in the charger to the mains. If its charging, the screen should show the voltage/amps it's charging at. If it continues to say off when when properly connected, then the battery voltage is likely so low (below 8.5volts) that the tool is not able to detect there's a battery connected.
