    Hello'
    I left the light on inside the car for 2 weeks. The car was parked in an underground heated parking lot. Effect, new centers battery plus 60ah discharged to 0.2W. I fired the car on the cables for 10 minutes, then the car started (mazda 2.0 petrol) and the next 20 minutes came, the voltage on the battery increased to 11.8W, the next day I connected a rectifier for PLN 50 from the supermarket, probably 4A. After 6 hours of charging, the battery voltage was 12.3W with a 12.6W rectifier.
    How much else to charge the battery, at the moment it is charging almost 10 hours and I am wondering whether to leave it under the charger overnight.

    Greetings

    and what the ammeter on the rectifier shows, if it is already close to zero, then you can give it up. anyway, a 60ah battery charged for 10 hours should be already charged, what is the density of the electrolyte, you can check it with a hydrometer.
    by the way, the rectifiers currently being produced have an automatic shutdown if aq is charged

    It is best to charge with the lowest possible current, but it increases the battery life for a longer time.
    If you drive a little car, it charges itself

    Well, because I understand that too long charging is not too good.
    The rectifier does not have an ammeter, it cost PLN 50, I also do not have the apathy to measure the density of the electrolyte, as most people probably do.
    Can I connect a meter in series with the rectifier to see how many amps are fed to the battery, I think it will probably not show anything.
    So I am going to remove the rectifier.

    Dude, you wrote that it is a 4A charger, the conclusion is that after 10 hours, your 60Ah battery is undercharged. Why? Each battery should be charged 0.1 capacity. The battery has 60Ah, i.e. the charging current should be 6A. It should be charged for about 10-12 hours. As for the meter - feel free to connect it in series between the charger and the battery. I would only advise you if you would like to leave it for the entire charging, connect slightly thicker wires (at least 1.5 square) because those from the meter are very thin and will keep you warm.
    I must add here that you have to charge it a little longer with this charger, about 16 hours.

    I disconnected for now, I prefer to charge during the day, I can continue tomorrow, the charger charged the battery to 12.3W, I checked the current at the end of charging 1.3A, so I think it has some adjustment, I started the car and charged the battery 20 minutes with an alternator (14.5W) and I leave it like that for now. The battery currently gives 12.75W. I loosened the plugs while charging and there was no gurgling at all, I guess that's good.
    One problem is that for now I'm not going anywhere in the car, maybe in 2 weeks. I understand that the battery will be fully charged after I drive 200 km. How can the battery not be fully charged?

    Ps. The meter showed the intensity :)

    In my opinion, you can leave it in this state. The current during charging drops, even to zero-1.6A at the end of charging, it indicates that the charging is correct - the current dropped. After a week, please check if the car fires. If it has a problem, it means that it has low power and unfortunately it will have to be recharged.
    By the way - when buying a rectifier, you must look at what this charger will charge. If the battery (like yours) 60Ah, the charger must give 1/10 of its capacity, i.e. 6A. Regards.

    The battery, so deeply discharged, should be charged with a current lower than 1/10 of the rated capacity. However, we extend the charging time. A hydrometer can be purchased at any automotive store - for a pittance. If you were lucky and the battery survived, it will have a density of 1.28 g / cm? at the end of the charge. It is important that the density is equal in all cells of the battery

    When fully charged, it will have about 14.7W with a rectifier and the cost of a hydrometer is about PLN 12, so it pays to buy

    And I'm afraid that after such a deep discharge, sulfation of the battery plates could occur. In such a case, you have to charge it for a long time and passionately, or perform desulphation charging, but it is quite a long and cumbersome procedure with no certainty of success. With the charger you have, you can even leave it to charge for up to two three days without overcharging.

    I am on a formal matter, V (olt) and not W (att).

    Yep, volt.

    I will add that the battery has had a constant temperature of about 18 degrees for the last few weeks.

    When buying a hydrometer, I would advise you to buy it with a float with a digital scale and not with colored dots. It's easier and more accurate to read the electrolyte density.

Topic summary

The discussion revolves around the charging process of a fully discharged 60Ah car battery after it was left unused for two weeks. The user initially charged the battery with a low-cost 4A rectifier, which resulted in a voltage increase to 12.3V after 6 hours. Participants advised that a battery should ideally be charged at 0.1 of its capacity (6A for a 60Ah battery) for optimal charging time of 10-12 hours. Concerns were raised about the potential for sulfation due to deep discharge, suggesting longer charging times and monitoring of electrolyte density with a hydrometer. The user was encouraged to check the battery's performance after a week and to consider leaving the battery on charge for an extended period without overcharging risks. The importance of using appropriate charging equipment and methods was emphasized throughout the discussion.
