Hi this video will show you how to recharge a car battery It is fully discharged Until well see 100% charge. I'll use a manual charger as the image. Start clean battery with a mixture of sodium bicarbonate and water. With this you will neutralize the sulfuric acid and copper sulfate Who are on the battery. Wear gloves and safety glasses That can cause burns are dangerous Especially eye Bubbles are observed, they are acid being neutralized. Battery clean and dry with a disposable towel Using a flathead screwdriver to unclog Vents Battery Do it carefully to avoid spilling the contents Vents clean and prevents dirt from falling into the battery In vents you can observe the liquid level of the battery In this case the liquid level is adequate If the metal plates are covered by water, it is not necessary to add liquid Otherwise, if the water is below the plates only should be added distilled water, which you can buy at any mall Do not add water beyond the height of the plates, vents need that space Uses a battery terminal cleaner to ensure proper charging.
Often feeding problems or boot of a vehicle They can be found at the battery terminals or vehicle Since when oxidized or sulphated, they have a high resistance to electric current flow What causes all sorts of electrical problems in vehicles. As you can see to clean the battery terminals voltage increased from 1.5 V to 3.5 V In this table it can be seen that this battery is loaded with 0% Because the voltage of 3.5 V is much lower than 11.89 V. This table is very important because it will allow us along with a multimeter The status of battery charge You must charge the battery in a ventilated because during recharging hydrogen gas which is explosive at high concentrations is generated.
You can visit the end of the video "Passing current car to car" To learn more about it. Connect the charger clamps alligators or manual batteries Connecting the charger to the electrical outlet The charger has a manual with a table with the estimated load times For recharging a varied type of batteries. In this case the information is presented to recharge A battery 550 CCA which is approximately 36.5 hours. To make your own calculations only need to use a rule of three So you will know the theoretical time will require your battery once you know the burden you have. This table is relative, it depends largely on the state of the battery Very worn, battery will take longer to charge than one that is not so much I recommend taking half of the estimated time and do a reading with the multimeter To see how the process of recharging the battery. First it disconnected from the wall outlet charger In this case is 12.48 V indicating that the battery is 75% of its total load. The process lasted about 30 hours reached 12.65 V ie 100% Here on the car and the battery status is observed, which is good Since not under 9 V to turn You can visit the video "Testing a car battery with a multimeter" to learn more about it.
Thank you for your time I wish I was helpful Until next video, over and out..
