valve regulated lead acid battery Bring Dead Lead Acid Battery to Live Again
Today, we will learn how to re-use this method for dead sealed lead-acid batteries. I tried this with a lot of dead and expired batteries where 90% of them were re-usedS: This method may not bring the battery to full performance in its original state, but at my speed the battery will work 50% ~ 70%. you need : -3cm syringe -Voltmeter or MultimeterBattery Charger or power supply-Crocodile line used with PSU-Safe with distilled water: Do not touch the water from the battery using goggles and chemical gloves it is an acid sealed battery and we will find the lid on the top of the battery, just take it off with a flat screwdriver like a photo and we will find 3 holes covered by the rubber cap and now we have to remove the cap as well. OK, now we will measure the voltage of this battery on my battery, it is 0. 76 volts only. This means that the battery is completely dry from the inside. In this step, we need to fill the battery with distilled water to activate the acid again, so refill it with a syringe until the water measures the voltage from all the holes and you will find that the voltage increases mVolts, this is good, if not without worry, after filling the battery with the water we need, we need to make sure it is dry with the inside of the battery so reactivate it again first, we will charge with 12 v dc. The output "I Am using ATX PSU" is 10 Am psu. Now wait 5 minutes until you see the bubbles coming out of the holeIf there are no bubbles from any of the 3 holes, you have to reverse the positive and negative and wait up to 1 ~ 3 minutes (this is a dangerous step, don't leave the battery alone in this state) OK, now you have to see the bubbles cut off the power immediately from holes like boiling, and reconnect the Yin and positive holes again. Now pull the wasted water from the top of the 3 holes with a syringe and let the battery charge until it charges up to 6. 9 v u should check every 1 hour, then dry it with a paper towel and cover everything that congratulates your battery on working again. Can you ask me? Sorry, my English is not good! !
