網上買了一個脈衝修復充電器，真的能修復壞電瓶嗎？測試後知道了 #我愛電器維修

Bought a pulse repair charger off the internet the other day Let's test it out today Let's have a look at it. Can you put this dead battery It's just a battery that can't be charged. can you fix it Let's test it today See if it fixes it look at the back of this charger Let's take a look at its parameters first. Its output current is 6A Well, the maximum output power is 90 watts The output voltage is 13.8 volts to 15.5 volts Applicable range 12 volts 220-120 lead-acid batteries can be used First of all, let's test it I have two batteries here This big battery let's test it This battery is a normal We see his voltage is 12.9 volts Explain that he has electricity Can be charged normally Let's test the bad battery again first look at his voltage You see only four o'clock Four point three volts Because the battery is too low use a normal charger Sure, it can't be charged. Now let's use this to test See if it can be charged give it this charger first Clamp on to this good battery let's take a look The charging effect of this charger After clamping it This will show uh the temperature of the charging environment His voltage is 13 volts 13 volts is the voltage inside the battery Then plug him in charger You can see that the charging light keeps flashing Then scroll here to explain. He can charge this good battery Then we put it Clamped on top of this bad battery Let's take a look and fix it Let's watch after we cut it because its battery is too low So you see, there won't be any display we plug it in charge it Charge it up and let's see The charging light doesn't blink either. If it doesn't flash, it means that. can't charge it Then click the repair button After clicking, the indicator light will flash. Then this side also started scrolling and jumping all over It's repair mode now Let's fix it for an hour Then measure it with a light meter See how much voltage is in it see if we can fix it Well now it's been fixed for an hour Then let's take a look Unplug this power first This will display the current voltage of the battery See how much power is charged It's eight volts now It was 4 volts just now It's charged to 8 volts now. And then plug it in again Explain that it can repair the battery What about after charging? Let's look at this light and it starts to flicker It can be charged normally, right? This is the charging current This is the charging voltage This is the current charging environment Looks like this battery pulse restorer still very useful
