When you charge batteries in series, you are charging the entire group of them all at the same time. The charger will stop charging when the entire group reaches a certain voltage. If the
3 天之前· Charging at a lower voltage may not effectively charge the battery. A 12-volt battery requires a specific charging voltage to fully recharge. If a 6-volt charger is used, it cannot supply sufficient voltage to overcome the battery''s charge requirement. This inadequacy may lead to incomplete charging, damaging the battery over time.
Battery size and state of charge. The size of your car''s battery pack is one of the most fundamental factors affecting charging time. A larger battery simply requires more energy to fill. For instance, a Nissan Leaf with a 40 kWh battery will charge more quickly than a Tesla Model S with a 100 kWh battery when using the same charger.

My UPS uses 2 lead-acid sealed batteries in series. It charges them only to 27.4 Volts, and it does that rather slowly (IIRC ~8h charge time), but a charger of this type and voltage can stay connected to the batteries "forever" without damaging them.
Charging depends on your battery connection in series vs parallel. Each wiring method has unique requirements for safe and efficient charging. Charging Batteries in Series. Use a charger matching the total voltage of the series setup. For example, a 24V charger is needed for a 24V setup. Current flows through the chain, charging all batteries
When you charge batteries in series, you are charging the entire group of them all at the same time. The charger will stop charging when the entire group reaches a certainvoltage. If the batteries are not each at the same voltage, this means that one battery is charging higher than the rest, and one is not charging as high as the rest.
When connecting or charging batteries in series your goal is to increase the output of your batteries nominal voltage rating. To do this you need to connect the POS (+) terminal of the first battery to the NEG (-) terminal of the second battery.
Charging Time of Battery = Battery Ah ÷ Charging Current T = Ah ÷ A and Required Charging Current for battery = Battery Ah x 10% A = Ah x 10% Where, T = Time in hrs. Example: Calculate the suitable charging current in Amps and the needed charging time in hrs for a 12V, 120Ah battery. Solution: Battery Charging Current:
This is why you replace both batteries at the same time and using the same model. All large banks have series charging. Charging them separately is just dodging the fact that one battery is in worse condition than the other. You are doing something right here .Seperate charging is better . It is normal to charge lead-acid batteries in series.
If you need to connect more than two batteries in series, you would make the following adjustment. Instead of connecting the POS (+) of the second battery to the charger, you would connect it to the NEG (-) of the third battery. You would continue this positive to negative pattern until you reach your last battery.
Battery Charging Time: Suppose we took 13 Amp for charging purpose, then, Charging time for 120Ah battery = 120 ÷ 13 = 9.23 Hrs. But this was an ideal case Practically, it has been noted that 40% of losses occurs in case of battery charging. Then 120 x (40 ÷ 100) = 48 (120Ah x 40% of losses) Therefore, 120 + 48 = 168 Ah ( 120 Ah + Losses)
